Arik: Update water leak issue, move to new section Resolved Issues

UPDATE: May 12, 2026
'''WORKING!''' -- [[#Water Leak|Water leak has been repaired, laser is operational]]

== General Info ==
=== Introduction ===
The big red laser cutter is a no-name model using a [https://ruidacontroller.com/wp-content/uploads/2021/10/RDC644XGS-Control-System-V1.3-Manual.pdf Ruida 644XG control board]. Its bed dimensions are about 730mm wide by 500mm deep. It looks like a 100 W CO2 laser.

The Melbourne Makerspace has the same laser and have a [https://wiki.melbournemakerspace.org/Laser%20Cutter nicely written wiki page on it].

=== Maintenance ===
''To be performed '''monthly'''''
* Clean [[#Lens & Mirrors|lens & mirrors]]
As needed
* Clean [[#Exhaust Fan|exhaust fan]]
* Clean cutaway collection area under bed

=== Dangers ===
[[File:ISO 7010 W001.svg|frameless|right|upright=0.5]]
''Be aware:'' lasers are very dangerous! Review these [https://ehs.mit.edu/workplace-safety-program/laser-cutter-safety/ safety guidelines], and carry an appropriate level of fear of the laser at all times. Hazards include:

'''Fire hazard'''
[[File:ISO 7010 W021.svg|frameless|right|upright=0.5]]
Lasers create high heat, and can cause materials to catch on fire. Certain materials and types of designs (i.e very dense/small objects) are more prone to fire.

To minimize fire risk, remember to...
# Never leave laser unattended. Be prepared to respond promptly in case of fire. Familiarize yourself with where the fire extinguisher and water spray bottle are before using. You should never see a prolonged flame while using the laser cutter.
# If you see a candle sized flame for more than 3 seconds while cutting, stop the laser, check/adjust bed height, power/speed settings, or use a different material.

'''Respiratory Hazard'''
[[File:ISO 7010 W071.svg|frameless|right|upright=0.5]]
Laser cutters create fumes and small particulates.

To minimize respiratory hazards, remember to...
# Only cut and engrave [[LASER SAFE material]]. Some materials can emit toxic fumes when laser cut, and should never be used in the laser cutter!
# Always have the ventilation fan on while using the laser cutter, and for a few minutes after you are done. Even laser safe materials aren't good to breathe in.
# Check in with other people in the room before using the laser cutter to see if they are sensitive to fumes. Be accommodating!

'''Laser Hazard'''
[[File:ISO 7010 W004.svg|frameless|right|upright=0.5]]
To minimize laser exposure hazards, remember to..
# Never look directly at the laser beam. While wearing ''laser eye protection'', you may look at the point that the laser is cutting your material. However, you should NEVER look directly into a laser beam, even if wearing safety goggles.
# Never run the laser cutter while the lid is open.

'''"Help, I tripped the breaker!"'''

This is how to reset the [[breaker]] that the laser (and sewing/3dprinting/hardware corner) is on.

== Known Issues ==
Firstly, this thing is '''''great''''' and we love it, flaws and all! Here are some quirks that should be solved or worked around.

''List of [[#Resolved Issues|resolved issues]]''

=== Crooked Bed ===
[[File:Crooked cut bed.png|thumb|right|alt=Graphic depicting cut bed and laser range, cut bed is crooked, rotated slightly anti-clockwise|Diagram of [[#crooked bed|crooked bed]]]]
The cut bed and guides are rotated slightly anti-clockwise, this means anything you align to the guide will be off a bit of what you may expect. For example, a straight horizontal line engraved on a piece aligned to the left edge guide will appear at a downward angle from left to right, on the piece. This also means if you start at (0, 0) and cut straight down ''you'll cut into the the guide'', oh no!

:'''Workaround:''' There is a simple jig that's been cut and lives on the bed, it's a brown piece of MDF. If you want a square cut using the jig, place your piece in the top left corner against the jig and position the laser at x=21.9, y=0 (two presses of the right arrow on the controller).

=== Non-Level Bed ===
There appears to be a slight slope starting at (0, 0) from left to right the bed rises about 1mm over 10cm. This warrants further investigation, might be only near top left of cut bed, doesn't appear/shouldn't have dramatic affect on cuts.

=== Laser Pointer ===
Not to be confused with the powerful laser used to engrave and cut, this is a helpful little laser that points to ''where'' a cut will be made. It appears not to work at the moment.

== Operation Instructions ==
# First turn on the laser cutter control switch, located on the right side of the machine.
<gallery mode="packed" heights="200">
File:Laser_control_switch.jpg|Showing laser control switch on
</gallery>

=== Preparing Material ===
# Put [[LASER SAFE material]] on the bed
# Use the control pad arrow keys to move the laser head above your material. We want it above the material to properly set the bed height
# Once laser head above material, use the knob inside the laser cutter to move the bed up and down. The correct height is about 3/4" '''(UPDATE: use 17mm block)''' above your material. You can use the "laser focus height" tool as reference.

File:Laser_bed_correct_bed_height_with_tool.jpg|Showing correct bed height for laser with tool
</gallery>

=== Turning on the laser and exhaust ===
# Turn on the exhaust fan by switching on the power strip on top of the laser cutter. You should hear the exhaust fan turn on. Also, switch on the air purifier on the desk.
# Enable the laser by turning on the laser switch on the left side of the machine, and turning the key on the front of the machine.

</gallery>

=== Preparing the file ===
[[File:Lightburn layer tips.png|thumb|LightBurn layer settings]]

The following steps should be done on the computer near the laser cutter, which has LightBurn installed on it.

# Open LightBurn on computer next to the laser cutter
# Import a vector file (svg, dxf, pdf, etc.), raster image, or create a design in LightBurn.
# Set the color of items to define how you want them cut or engraved, then double click the colors in the pane on the right to set the laser speed, power, and other features associated with that color. Black can be used to cut and red to etch, for instance. Use this chart to get a ballpark reference for speed and power settings: '''[[Big red laser cutter settings]]'''. It is recommended to do a "test cut" before cutting out a large file to be sure your speed and power settings are good.
# Select "absolute coordinates" to define the placement relative to the bed. Select "user origin" to set the placement on the bed manually. The device should be set to ttyUSB0, Ruida664GX.
# Once happy with design, click “Send”
# Enter a name (or just use default to override) and press enter.
# Wait for the file to send.

=== Running the laser ===
The following steps should be done using the control panel on the laser cutter itself.

# On the laser cutter control panel, press "File" to see available files.
# Scroll and press “Enter” to select a file.
# Set the origin if necessary.
# Press “Frame" to confirm placement. When you press this, the laser cutter head will trace around the max coordinates, to show you where your design will be cut.
# If the frame is correct press “Start”, and the laser will run.

=== Having Trouble Setting the Origin? ===
If you are using LightBurn to compose your project, be sure to use the setting "Current Position". 
Otherwise, LightBurn may override any origin you set at the laser cutter.

Setting the origin on the laser cutter is easy. 
On the front panel there are 4 arrow keys. You can use these to move the "head" around.
Pressing the "Origin" button sets that spot to be the origin of where cutting starts. Typically, this is the upper left
of the bounding rectangle around your artwork.
You may find that moving the "head" is much easier than moving the material placed on the bed!

== Cleaning ==
=== Lens & Mirrors ===
'''''Very carefully.''''' Clean the lens and mirrors monthly.

=== Exhaust Fan ===
If the exhaust fan is not working well, it might need to be cleaned.

To clean, detach the fan and base from the laser cutter. The green area circled in the below picture is where you need to get access, the '''intake'''.

== Other software ==
As mentioned, RDWorks can also be used. We haven't tried it yet but it seems it's a free download [https://www.thunderlaser.com/laser-download from here].

Some of the software (downloaded from the above link) is on the hard drive of wasp.local which is a desktop computer under the 3D printer desk, in a folder called ~/laser-backup/

[https://spaz.org/~jake/sudoroom/Big_red_laser_cutter/ The above software has also been downloaded and stored here]

It was setup with an IP address of 100.64.64.69 (by pressing buttons through the menu) but it had no ports open and then we just switched over to USB to the computer and it was working fine. The same software might work over ethernet but we didn't try.

== Trying other things ==
Andy is trying to find software to control the laser cutter. I can generate gcode instructions in Inkscape, but I don't know how to send them to the printer over USB.

I'm trying to install [https://laserweb.yurl.ch/|LaserWeb].

I ran the commands here: https://laserweb.yurl.ch/documentation/installation/36-install-raspberry-pi. But the server gave an error when started:

== Stuff made on the big red laser cutter ==

* I cut some 1/4" clear plastic suspected to be acrylic. Used 0.5mm/sec 100% / 40% power. It cut all the way through but the edge was rough.

== Stuff seen around the space ==


== Ventilation ducting ==

=== History ===
A plastic adapter was 3D printed to connect the 6" outlet of the exhaust fan to the 8" flexible duct leading to the roof hole:
{| class="wikitable mw-collapsible mw-collapsed"
|+ class="nowrap" | SCAD instructions
|
<nowiki>
laserduct.scad
THICKNESS=1.5*25.4;
ID=5.75*25.4;
ID_LIP=ID-(0.25*25.4);
ID_LIP_THICK=0.2*25.4;
OD=7.75*25.4;
OD_LIP=OD+0.2*25.4;
OD_LIP_THICK=0.2*25.4;
difference() {
color("BLUE") cylinder(d1=OD_LIP, d2=OD, h=THICKNESS, $fn=100);
{
translate([0,0,ID_LIP_THICK]) cylinder(d=ID, h=THICKNESS, $fn=100);
translate([0,0,-0.5]) cylinder(d=ID_LIP, h=THICKNESS, $fn=100);
}
}</nowiki>
|}

Also the duct/roof interface was improved and a new stand was made for the extractor fan. Yay for milk crates!

== Resolved Issues ==

=== Water Leak ===
'''Update: 2026-05-12'''
FIXED! The water pressure switch was replaced with a less leaky one.

'''Update: 2026-05-05'''
The offending device is a ''water pressure level switch'', we will either salvage one from a dishwasher or washing machine, or order a new one online. If you have access to either a dishwasher or washing machine, or one of these switches please let us know!

'''Update: 2026-04-30'''
Water was seen leaking from the front left of the machine while switched on. Upon investigation it was found to be dripping from the bottom of a device mounted inside near the back left corner. A water inlet enters the body of the laser cutter and is split, one hose goes to the offending device. This device appears to maybe be a water sensor of some sort.

Big red laser cutter

2026-05-06T03:47:04Z

Arik: Update water leak issue

UPDATE: May 5, 2026
'''Out of order''' -- [[Big_red_laser_cutter#Water_Leak_ADDRESS_BEFORE_USING|Water was seen leaking from the laser cutter!]]

== General Info ==
=== Introduction ===
The big red laser cutter is a no-name model using a [https://ruidacontroller.com/wp-content/uploads/2021/10/RDC644XGS-Control-System-V1.3-Manual.pdf Ruida 644XG control board]. Its bed dimensions are about 730mm wide by 500mm deep. It looks like a 100 W CO2 laser.

The Melbourne Makerspace has the same laser and have a [https://wiki.melbournemakerspace.org/Laser%20Cutter nicely written wiki page on it].

=== Maintenance ===
''To be performed '''monthly'''''
* Clean [[#Lens & Mirrors|lens & mirrors]]
As needed
* Clean [[#Exhaust Fan|exhaust fan]]
* Clean cutaway collection area under bed

=== Dangers ===
[[File:ISO 7010 W001.svg|frameless|right|upright=0.5]]
''Be aware:'' lasers are very dangerous! Review these [https://ehs.mit.edu/workplace-safety-program/laser-cutter-safety/ safety guidelines], and carry an appropriate level of fear of the laser at all times. Hazards include:

'''Fire hazard'''
[[File:ISO 7010 W021.svg|frameless|right|upright=0.5]]
Lasers create high heat, and can cause materials to catch on fire. Certain materials and types of designs (i.e very dense/small objects) are more prone to fire.

To minimize fire risk, remember to...
# Never leave laser unattended. Be prepared to respond promptly in case of fire. Familiarize yourself with where the fire extinguisher and water spray bottle are before using. You should never see a prolonged flame while using the laser cutter.
# If you see a candle sized flame for more than 3 seconds while cutting, stop the laser, check/adjust bed height, power/speed settings, or use a different material.

'''Respiratory Hazard'''
[[File:ISO 7010 W071.svg|frameless|right|upright=0.5]]
Laser cutters create fumes and small particulates.

To minimize respiratory hazards, remember to...
# Only cut and engrave [[LASER SAFE material]]. Some materials can emit toxic fumes when laser cut, and should never be used in the laser cutter!
# Always have the ventilation fan on while using the laser cutter, and for a few minutes after you are done. Even laser safe materials aren't good to breathe in.
# Check in with other people in the room before using the laser cutter to see if they are sensitive to fumes. Be accommodating!

'''Laser Hazard'''
[[File:ISO 7010 W004.svg|frameless|right|upright=0.5]]
To minimize laser exposure hazards, remember to..
# Never look directly at the laser beam. While wearing ''laser eye protection'', you may look at the point that the laser is cutting your material. However, you should NEVER look directly into a laser beam, even if wearing safety goggles.
# Never run the laser cutter while the lid is open.

'''"Help, I tripped the breaker!"'''

This is how to reset the [[breaker]] that the laser (and sewing/3dprinting/hardware corner) is on.

== Known Issues ==
Firstly, this thing is '''''great''''' and we love it, flaws and all! Here are some quirks that should be solved or worked around.

=== Water Leak ''ADDRESS BEFORE USING'' ===
'''Update: 2026-05-05'''
The offending device is a ''water pressure level switch'', we will either salvage one from a dishwasher or washing machine, or order a new one online. If you have access to either a dishwasher or washing machine, or one of these switches please let us know!

'''Update: 2026-04-30'''
Water was seen leaking from the front left of the machine while switched on. Upon investigation it was found to be dripping from the bottom of a device mounted inside near the back left corner. A water inlet enters the body of the laser cutter and is split, one hose goes to the offending device. This device appears to maybe be a water sensor of some sort.

<gallery mode="slideshow">

File:Laser_cutter_water_pressure_switch_2.jpeg|Pressure switch removed angle 1
File:Laser_cutter_water_pressure_switch_3.jpeg|Pressure switch removed angle 2
</gallery>

=== Crooked Bed ===
[[File:Crooked cut bed.png|thumb|right|alt=Graphic depicting cut bed and laser range, cut bed is crooked, rotated slightly anti-clockwise|Crooked bed]]
The cut bed and guides are rotated slightly anti-clockwise, this means anything you align to the guide will be off a bit of what you may expect. For example, a straight horizontal line engraved on a piece aligned to the left edge guide will appear at a downward angle from left to right, on the piece. This also means if you start at (0, 0) and cut straight down ''you'll cut into the the guide'', oh no!

:'''Work around:''' There is a simple jig that's been cut and lives on the bed, it's a brown piece of MDF. If you want a square cut using the jig, place your piece in the top left corner against the jig and position the laser at x=21.9, y=0 (two presses of the right arrow on the controller).

=== Non-Level Bed ===
There appears to be a slight slope starting at (0, 0) from left to right the bed rises about 1mm over 10cm. This warrants further investigation, might be only near top left of cut bed, doesn't appear/shouldn't have dramatic affect on cuts.

=== Laser Pointer ===
Not to be confused with the powerful laser used to engrave and cut, this is a helpful little laser that points to ''where'' a cut will be made. It appears not to work at the moment.

== Operation Instructions ==
# First turn on the laser cutter control switch, located on the right side of the machine.
<gallery mode="packed" heights="200">
File:Laser_control_switch.jpg|Showing laser control switch on
</gallery>

=== Preparing Material ===
# Put [[LASER SAFE material]] on the bed
# Use the control pad arrow keys to move the laser head above your material. We want it above the material to properly set the bed height
# Once laser head above material, use the knob inside the laser cutter to move the bed up and down. The correct height is about 3/4" '''(UPDATE: use 17mm block)''' above your material. You can use the "laser focus height" tool as reference.

</gallery>

=== Turning on the laser and exhaust ===
# Turn on the exhaust fan by switching on the power strip on top of the laser cutter. You should hear the exhaust fan turn on. Also, switch on the air purifier on the desk.
# Enable the laser by turning on the laser switch on the left side of the machine, and turning the key on the front of the machine.

</gallery>

=== Preparing the file ===
[[File:Lightburn layer tips.png|thumb|LightBurn layer settings]]

The following steps should be done on the computer near the laser cutter, which has LightBurn installed on it.

# Open LightBurn on computer next to the laser cutter
# Import a vector file (svg, dxf, pdf, etc.), raster image, or create a design in LightBurn.
# Set the color of items to define how you want them cut or engraved, then double click the colors in the pane on the right to set the laser speed, power, and other features associated with that color. Black can be used to cut and red to etch, for instance. Use this chart to get a ballpark reference for speed and power settings: '''[[Big red laser cutter settings]]'''. It is recommended to do a "test cut" before cutting out a large file to be sure your speed and power settings are good.
# Select "absolute coordinates" to define the placement relative to the bed. Select "user origin" to set the placement on the bed manually. The device should be set to ttyUSB0, Ruida664GX.
# Once happy with design, click “Send”
# Enter a name (or just use default to override) and press enter.
# Wait for the file to send.

=== Running the laser ===
The following steps should be done using the control panel on the laser cutter itself.

# On the laser cutter control panel, press "File" to see available files.
# Scroll and press “Enter” to select a file.
# Set the origin if necessary.
# Press “Frame" to confirm placement. When you press this, the laser cutter head will trace around the max coordinates, to show you where your design will be cut.
# If the frame is correct press “Start”, and the laser will run.

=== Having Trouble Setting the Origin? ===
If you are using LightBurn to compose your project, be sure to use the setting "Current Position". 
Otherwise, LightBurn may override any origin you set at the laser cutter.

Setting the origin on the laser cutter is easy. 
On the front panel there are 4 arrow keys. You can use these to move the "head" around.
Pressing the "Origin" button sets that spot to be the origin of where cutting starts. Typically, this is the upper left
of the bounding rectangle around your artwork.
You may find that moving the "head" is much easier than moving the material placed on the bed!

== Cleaning ==
=== Lens & Mirrors ===
'''''Very carefully.''''' Clean the lens and mirrors monthly.

=== Exhaust Fan ===
If the exhaust fan is not working well, it might need to be cleaned.

To clean, detach the fan and base from the laser cutter. The green area circled in the below picture is where you need to get access, the '''intake'''.


<gallery mode="packed" heights="200">

File:Laser_fan_dirty.jpg|Dirty exhaust fan '''intake''', ''an N95 mask is recommended'', use a vacuum and toothbrush/wire brush to clean.
File:Laser_fan_clean.jpg|Clean exhaust fan '''intake'''
</gallery>

== Other software ==
As mentioned, RDWorks can also be used. We haven't tried it yet but it seems it's a free download [https://www.thunderlaser.com/laser-download from here].

Some of the software (downloaded from the above link) is on the hard drive of wasp.local which is a desktop computer under the 3D printer desk, in a folder called ~/laser-backup/

[https://spaz.org/~jake/sudoroom/Big_red_laser_cutter/ The above software has also been downloaded and stored here]

It was setup with an IP address of 100.64.64.69 (by pressing buttons through the menu) but it had no ports open and then we just switched over to USB to the computer and it was working fine. The same software might work over ethernet but we didn't try.

== Trying other things ==
Andy is trying to find software to control the laser cutter. I can generate gcode instructions in Inkscape, but I don't know how to send them to the printer over USB.

I'm trying to install [https://laserweb.yurl.ch/|LaserWeb].

I ran the commands here: https://laserweb.yurl.ch/documentation/installation/36-install-raspberry-pi. But the server gave an error when started:

== Stuff made on the big red laser cutter ==

* I cut some 1/4" clear plastic suspected to be acrylic. Used 0.5mm/sec 100% / 40% power. It cut all the way through but the edge was rough.

== Stuff seen around the space ==


== Ventilation ducting ==

=== History ===
A plastic adapter was 3D printed to connect the 6" outlet of the exhaust fan to the 8" flexible duct leading to the roof hole:
{| class="wikitable mw-collapsible mw-collapsed"
|+ class="nowrap" | SCAD instructions
|
<nowiki>
laserduct.scad
THICKNESS=1.5*25.4;
ID=5.75*25.4;
ID_LIP=ID-(0.25*25.4);
ID_LIP_THICK=0.2*25.4;
OD=7.75*25.4;
OD_LIP=OD+0.2*25.4;
OD_LIP_THICK=0.2*25.4;
difference() {
color("BLUE") cylinder(d1=OD_LIP, d2=OD, h=THICKNESS, $fn=100);
{
translate([0,0,ID_LIP_THICK]) cylinder(d=ID, h=THICKNESS, $fn=100);
translate([0,0,-0.5]) cylinder(d=ID_LIP, h=THICKNESS, $fn=100);
}
}</nowiki>
|}

Also the duct/roof interface was improved and a new stand was made for the extractor fan. Yay for milk crates!

Arik: Add Overview section

'''Tuesdays'''
'''20:00 (8 PM) — ''late'''''
Check upcoming events: https://sudoroom.org/events/categories/hack-night/

== Overview ==
The Fixit Clinic runs Tuesday nights alongside the [[HardwareHackNight|Hardware and SoftWEAR Project Night]]. It is all about reusing electronics, having the right to repair, and other cool issues!

Not only is the Fixit Clinic at Sudo Room but also at many other great places around the world, see https://fixitclinic.blogspot.com for more info.

We even fixed an expensive hardware device for our sister, biohacking lab, Counter Culture Labs as evidenced below. This saved tons of money and prevented wasting perfectly great equipment :)

2026-05-01T23:17:08Z

Arik: Clarify

Is the device going to be brought back, and if not should we move, archive, or delete this page as it's about something no longer at Sudo Room? Is there protocol or precedent for this sort of situation where we have a page on something that then leaves Sudo Room?

Arik: Add directions link, update poster size

'''Every ''fourth'' Thursday of the month'''
'''19:00 (7 PM) — ''super late!'''''
Check upcoming events: https://sudoroom.org/events/categories/party/

== The What ==
''Resurrected January 2026''

Hang out with radical nerds, make something, hack away, print in another dimension (three currently available), jam to some tunes, organize the chaos, contribute to the chaos, play games (video, tabletop, board, card, party), share and enjoy snacks, relax, and have ''fun!''

Got an idea for a theme or activity? Let us know!

Meetings

2026-05-01T22:33:12Z

Arik: Add regular event info, update information and phrasing, cleanup formatting

__NOTOC__
'''Twice a month'''
'''Every ''second'' Thursday 19:00 (7 PM)'''
'''Every ''last'' Sunday 16:00 (4 PM)'''
Check upcoming events: https://sudoroom.org/events/categories/member-meeting/

== Overview ==
Sudo Room's official meetings are bureaucratic, sometimes fun, and usually more functional than rumored. We try to handle conflicts respectfully.


<pre>sudo make meeting --excellence TRUE</pre>

== Join ==
We meet in a hybrid format, in-person at Sudo Room and online.

[[Directions | Getting to Sudo Room]]

[https://meet.waag.org/turtlesturtlesturtles Online Jitsi video conference]

== Future meeting topics ==
Add topics to this etherpad: https://pad.riseup.net/p/sudo-proposals

If you have something you want addressed consider attending and helping to guide the discussion on it.

== Etherpad ==
We keep our agenda on an etherpad. The etherpad is projected on a big screen for everyone to see. Anyone who knows the URL can collaboratively edit it on their laptop. After the meeting, its contents are copied to our wiki - that's how we keep record. Then we clear it for the next meeting and people can add items throughout the week. Ideally someone posts a summary to the mailing list, but that doesn't always happen.

Unfortunately, in the past our etherpad has caught the attention of online troll dens who like to overwhelm it and make it unusable. For this reason, we don't post the address online. Sorry! '''These addresses''' had been used in the past, and '''are obsolete''':

* https://pad.riseup.net/p/sudoroommeeting

See [[Meeting template]] when starting a new meeting!

== Archive ==
Each past meeting gets its own page, and we link to them here.

=== Physically ===
Sudo Room is located in the Omni Commons building, at the corner of 48th and Shattuck, in North Oakland.

The nearest major intersection is 51st and Shattuck, right next to the highway 24 on/off-ramps.

We're 1/2 mile north of MacArthur BART station; which is approximately 10 minutes at average human walking speed.

=== Virtually ===
It won't be the same, but you can join us virtually!

[https://meet.waag.org/turtlesturtlesturtles Online Jitsi video conference]

== Getting in ==
Our main entrance is ''not'' the one on Shattuck. Walk down 48th St. to the building's side door and follow the instructions posted there for accessing Sudo Room.
<noinclude>== Getting out ==
We are programmed to receive

You can check out any time you like

But you can never leave

== Getting started with baklava ==
* Preheat oven to 175°C
* Probably grease a pan
* Make phyllo dough (you probably should have done this before turning on the oven)

== Getting weird ==

''We are working on building quick start and "how to" guides that include videos and cartoons on using the synthesizer.'' 

=== Manual ===
There is a printed manual of the synthesizer.

Welcome to Sudo Room! This page should help answer any questions you might have about Sudo Room, how to become a member, how to access the space, and more!

__TOC__

== What is Sudo Room? ==
Sudo Room is an open membership hackerspace in Oakland, California.

We are a collaborative and creative community of technologists, activists, artists, and all combinations inbetween and beyond. Most importantly, we are all human beings interested in and working toward positive social change. We strive toward horizontal leadership, meaning all members are equally empowered leaders in the community. Sudoers present and future have a great diversity of interests, so we emphasize inclusivity and solidarity amongst ourselves and with others.

<blockquote>"It's not easy to say what a hackerspace is exactly. You know it when you're in one, but they're all unique because people are so unique." 
Mitch Altman of [https://www.noisebridge.net/ Noisebridge]</blockquote>

=== What does "sudo" mean? ===
[https://en.wikipedia.org/wiki/Sudo Sudo] is a software command that stands for "super user do". It's pronounced "sue-dough" or "sue-due".

== Who is welcome at Sudo Room? ==
Sudo Room is committed to [[Access|ACCESS]], so anyone is welcome! You don't have to be "techie," you don't have to be a member, you don't have to know about computers or know how to write code. If you're not sure whether you are the kind of person who is welcome at Sudo Room, the answer is YES.

We are wheelchair accessible.

Young children need to be supervised by a guardian. We don't have childcare available. Sorry!

== Where is Sudo Room and how do I get in? ==
Sudo Room is located at 549 48th St in Temescal, North Oakland. The building, called the [https://omnicommons.org Omni Oakland Commons], is home to several other collectives. Ring the bell to get in. Full info on where we are and how to get in can be found [[Getting_there | here]]! 

== What are Sudo Room's hours? ==
For members, Sudo Room is accessible 24/7. For visitors and non-members, the space is open whenever another member is here to let you in. People are usually in the space most evenings and weekends. We are also here for any events (check our [http://sudoroom.org/calendar/ Calendar] for events). To get in, ring the bell at the entrance (see [[Getting_there|here]]) and if someone is here, they will open the door. To find out ahead of time whether someone is here, the best place to ask is in our [https://sudoroom.org/chat/ chatroom]. Alternately, you can email the [mailto:sudo-discuss@lists.sudoroom.org listserv] and ask if someone is at the space.

== What kinds of things take place at Sudo Room? ==
Sudoers use the space to do everything from working on their own computers to building desks! We make 3D printed jewelry, develop inventory systems for hackerspaces, meet up to work on volunteer projects like [http://oaklandwiki.org Oakland Wiki] and the [https://peoplesopen.net Peoples Open Network], use our library to learn new things, host free coding classes and meetups based in co-learning and collaboration, and build radio stations. Check out our full list of projects [[Projects | here]].

== What equipment is available at Sudo Room? ==
We are adding new equipment daily but our current major resources include two [http://en.wikipedia.org/wiki/3D_printing 3D printers], woodworking equipment, laptops, soldering and electronics station, sewing machines, workspace, meeting space, library, [[Audio]] production equipment, and a [http://en.wikipedia.org/wiki/CNC_router CNC router].

== How can I get involved with Sudo Room? ==
There are a number of ways to get involved, but the easiest is to come by the space and check it out. You can also sign up for our [mailto:sudoroom@lists.hackerspaces.org listserv], join our [http://webchat.freenode.net/?channels=sudoroom chatroom], or come to one of our weekly organizational meetings that take place at 7PM every Wednesday.

== How do I become a member? ==
# Introduce yourself in person or on the [https://lists.sudoroom.org/listinfo/sudo-discuss mailing list] or at a meeting
# [https://sudoroom.org/membership/ Sign up] and start contributing!
# Create a wiki user page or email some contact info to [mailto:info@sudoroom.org info@sudoroom.org]
# Wait a short while
# '''''Poof!''''' You're a member!

Existing members can block you if they know you to be a violent, malicious or otherwise problematic person, but this is rare.

=== What does membership mean? ===
The primary benefit of being a member is getting 24/7 access to '''Sudo Room''', an open, non-hierarchical, collaborative community of humans, including tech developers, citizen scientists, activists, artists--and all combinations in between and beyond!--who are interested in and working towards social change. Access to the space and to all the Sudo Room resources is one of our core values, so everyone is able to access the space and use our resources whether they are a member or not. However, members have guaranteed access to the space and Sudo Room assets. For more information on member benefits, see our [[Articles of Association]].

=== How do I pay member dues or donate to Sudo Room? ===
There are four ways to pay member dues:
# Create an account on [https://sudoroom.org/humans sudo-humans] and sign up to make a one-time or monthly donation.
# Direct deposit to the Sudo Room - contact
# Check made out to Sudo Room (easiest to bring to Wednesday night meetings)
# Cash (easiest to bring to Wednesday night meetings)
# Send us some Bitcoin - see the link to the left :-)

== How is Sudo Room funded? ==
Sudo Room is, for the most part, funded by member contributions, though we also receive [https://sudoroom.org/membership donations] from the public, and the occasional small grant.

== What is the history of Sudo Room? ==
Sudo Room started as a website in 2011. After holding meetings in cafes, then at the downtown coworking space [http://techliminal.com/ Tech Liminal], we moved into a small space in 2135 Broadway in July 2012. In Nov. 2012, we moved into our first real space at 2141 Broadway, which was attached to a common area also shared by the Bay Area Public School, a free university. In July of 2014, after meeting weekly for over 6 months, we moved into our current space, the [https://omnicommons.org Omni Oakland Commons], along with several other aligned collectives.

Join us and help us write the next chapter!

== New Members ==
* Check out our [[Articles of Association]]. The articles outline how we run our organization, how we do our budget, how we run our meetings, how membership is determined, benefits of membership, conflict resolution, and more.
* Come to our meetings at 7PM on Wednesday nights.
* Say hello on the [http://lists.sudoroom.org/listinfo/sudo-discuss listserv] or in the [http://sudoroom.org/chat chatroom].
* Drop by any time and meet everyone! For info on what's happening in the space on any given day, refer to our [http://sudoroom.org/calendar Calendar].

== Can I have an event there? ==
;Maybe! We love events like these:
* For a good cause
* Local, community-based
* Disability accessible
* Free, sliding scale, pay what you can, donation-based, nobody turned away

;We don't like events like these:
* Pay-walled
* Socially oppressive
* Corporate or military sponsored

;To make an event:
* If you are a member - use '''do-ocracy''':
**Check the [https://sudoroom.org/calendar/ calendar] for conflicts
**Get an existing user to create you a Wordpress account and [https://sudoroom.org/wordpress/wp-login.php log in]
**[https://sudoroom.org/wp-admin/post-new.php?post_type=ai1ec_event Add] your event
* If you are not a member:
** If you anticipate any problems, reach out to the [https://lists.sudoroom.org/listinfo/sudo-discuss mailing list] or to [mailto:info@sudoroom.org info@sudoroom.org].
** Get approval by sudoers. A good way to do this is at one of our [https://sudoroom.org/ai1ec_event/weekly-meetup-2/ weekly general meetings]. Showing up in person is preferred. But if you can't make it you can ask for the action to happen over the sudo-discuss mailing list (as linked above), and maybe you can get approval over email.

We can promote your event on our [https://sudoroom.org/blog blog], [https://twitter.com/sudoroom twitter], etc. Just ask!

== What's your legal structure? ==
It's still evolving. Here's some history:
* In November 2011, Sudo Room held its [[First_Meeting|first meeting]]. We've held [[Meetings|regular meetings]] ever since then.
* In early 2012, we agreed to an [[Articles_of_Association|Articles of Association]].
* In late 2013, we filed [[Articles_of_Incorporation|Articles of Incorporation]] with the state of California, and elected a [[Board|Board of Directors]]

== Can I store X at Sudo Room ==
You can put a useful tool or some hacker ore neatly at Sudo Room. Once you put something out at Sudo and unless it says "do not hack on it" (and even then) there is no guarantee as to what will happen. You can however also rent a locker at Sudo if you need private space, it is $25 per month.

== When is Sudo Room open? ==
Sudo Room doesn't have official hours. If you are a member you can get 24-hour access to let yourself in. If you are not a member, you will have to depend on at least one other member being there to let you in, and you would be their guest.

Typically there people at Sudo Room from 11am to 2am (or later 4am) most days of the week - but no guarantees.

Soon we will have a phone number you can call.

== Can you fix my iPhone/iPad/Android Phone/Tablet/Laptop/other Device? ==
Complicated. Sudo Room does not offer fix-it services. You can come to Sudo Room, use all our tools, and ask for help in fixing it yourself. Maybe a nice sudoer - and there are some nice sudoers - will help point you in the right direction or explain something that that youtube DIY fixing video didn't go over. If you want to find someone that might be able to help online you can contact the [https://lists.sudoroom.org/listinfo/sudo-discuss high-traffic mailing list]. In general there are no guarantees, but if you are dedicated you can learn to fix your own iBad.

Tuesday nights during [[HardwareHackNight|Hardware Hack Night]] there is usually an ongoing [[FixitClinic|Fixit Clinic]]

== Can you help me with Software Problem X? ==
Basically this is the same question as [[#Can you fix my iPhone/iPad/Android Phone/Tablet/Laptop/other Device?|Can you fix my iPhone/iPad/Android Phone/Tablet/Laptop/other Device?]]. Maybe, you'll have to find someone willing to help, which is possible, maybe on the mailing lists or IRC.

== Where is the overhead light switch ==
It's in the hallway outside of Sudo Room, halfway to the exterior door

[[File:Women and Non Binary coding night.jpg|thumb]]

[[File:Hacknight2.png|thumb]]

== What is Women and Non Binary Hack Night? ==

"Coding Owls" is a weekly event for gender minorities in tech (women, nonbinary, trans, and gender non-conforming people) to discuss and work on projects together. Bring your computer and a coding project and have fun!

The event takes place at Sudo Room, a creative community and hackerspace at Omni Commons.

The Sudo Room, a creative community and hackerspace at Omni Commons, invites all Women/NB people for “Coding Owls – A WNB Coding Night”: bring your computer and a coding project and have fun!

We can help each other if you have coding related questions/bugs or just keep company while hacking! If you are a beginner, we can help you get started (even if you’ve never coded before!). And if you’re an intermediate programmer looking for a challenge, we can help you find problems to work on.

No computer? No problem: we can provide one for the night. Coders of all abilities are welcome!

All coding languages are welcome! Bringing a WNB friend is highly recommended.

Coding is more fun with friends! Join in person if you’re in Oakland or online anywhere else in the world!

The idea is also to be a '''safe space for WNB in the tech world''', besides promoting empowerment, also to provide emotional support for those facing challenges in a work environment, tech job search or anything else related.

== Path to Freedom ==
We are creating some “pathways” to freedom for women at the space.
typically women tend to get sucked into the predictable buckets at tech and hackerspaces - the den mom who organizes meetings, takes notes and provides emotional support. The crafting circle that doesn’t touch on the fine arts or larger ideas. The education section that only focuses on caretaking of kids, doing chores and doesn’t explore larger ideas such as the theory of the mind or educational academic papers.

While everyone is welcome to explore what we want, we’d like to “jam” the default channels that automatically send women into caretaking roles, mindless administration, and instead of provoke them to use their minds in new ways!

The first 3 pathways would be:

- '''Women Audio Engineering path to Freedom''' - women tend to be restricted to singing and dancing in electronic music and beyond, with very little visibility in audio engineering and DJing. What would happen if we create a path to freedom where they get to explore?

- '''Women theory of the mind''' - If you get into education are you automatically getting channeled into roles around childcare of children’s education? Why not work further and instead explore academics and educational theory?

Instead of being pushed into teaching kids, maybe women can study [[LearningtToLearn]] - why should women be routed into mindless childcare when instead they might be inclined to do things more cerebral?

- '''Women in the Fine Arts''' - There is a wealth of women’s crafts, but what if women could go to hackerspaces and go beyond sewing, knitting and crafting and also explore color theory, abstraction and conceptual art? Why stay hedged into one area just because traditional and social pressure demands it? We can also introduce reading art theory papers and visiting museums.

=== Host ===
Your host: Juliana A. (pronouns she/her) is originally from Brazil, has been living in the US for 10 years, and has been working as a software engineer since 2020, after finishing a software engineering bootcamp for women/nb people only. She has worked with Ruby on Rails, Python, SQL, JavaScript, React, Typescript.

Big red laser cutter

2026-05-01T04:23:11Z

Arik: Fix link

UPDATE: April 30, 2026
'''Out of order''' -- [[Big_red_laser_cutter#Water_Leak_ADDRESS_BEFORE_USING|Water was seen leaking from the laser cutter!]]

== General Info ==
=== Introduction ===
The big red laser cutter is a no-name model using a [https://ruidacontroller.com/wp-content/uploads/2021/10/RDC644XGS-Control-System-V1.3-Manual.pdf Ruida 644XG control board]. Its bed dimensions are about 730mm wide by 500mm deep. It looks like a 100 W CO2 laser.

The Melbourne Makerspace has the same laser and have a [https://wiki.melbournemakerspace.org/Laser%20Cutter nicely written wiki page on it].

=== Maintenance ===
''To be performed '''monthly'''''
* Clean [[#Lens & Mirrors|lens & mirrors]]
As needed
* Clean [[#Exhaust Fan|exhaust fan]]
* Clean cutaway collection area under bed

=== Dangers ===
[[File:ISO 7010 W001.svg|frameless|right|upright=0.5]]
''Be aware:'' lasers are very dangerous! Review these [https://ehs.mit.edu/workplace-safety-program/laser-cutter-safety/ safety guidelines], and carry an appropriate level of fear of the laser at all times. Hazards include:

'''Fire hazard'''
[[File:ISO 7010 W021.svg|frameless|right|upright=0.5]]
Lasers create high heat, and can cause materials to catch on fire. Certain materials and types of designs (i.e very dense/small objects) are more prone to fire.

To minimize fire risk, remember to...
# Never leave laser unattended. Be prepared to respond promptly in case of fire. Familiarize yourself with where the fire extinguisher and water spray bottle are before using. You should never see a prolonged flame while using the laser cutter.
# If you see a candle sized flame for more than 3 seconds while cutting, stop the laser, check/adjust bed height, power/speed settings, or use a different material.

'''Respiratory Hazard'''
[[File:ISO 7010 W071.svg|frameless|right|upright=0.5]]
Laser cutters create fumes and small particulates.

To minimize respiratory hazards, remember to...
# Only cut and engrave [[LASER SAFE material]]. Some materials can emit toxic fumes when laser cut, and should never be used in the laser cutter!
# Always have the ventilation fan on while using the laser cutter, and for a few minutes after you are done. Even laser safe materials aren't good to breathe in.
# Check in with other people in the room before using the laser cutter to see if they are sensitive to fumes. Be accommodating!

'''Laser Hazard'''
[[File:ISO 7010 W004.svg|frameless|right|upright=0.5]]
To minimize laser exposure hazards, remember to..
# Never look directly at the laser beam. While wearing ''laser eye protection'', you may look at the point that the laser is cutting your material. However, you should NEVER look directly into a laser beam, even if wearing safety goggles.
# Never run the laser cutter while the lid is open.

'''"Help, I tripped the breaker!"'''

This is how to reset the [[breaker]] that the laser (and sewing/3dprinting/hardware corner) is on.

== Known Issues ==
Firstly, this thing is '''''great''''' and we love it, flaws and all! Here are some quirks that should be solved or worked around.

=== Water Leak ''ADDRESS BEFORE USING'' ===
[[File:Laser_cutter_leaking_device.jpeg|thumb|right|upright=1|Water leaks from this thing]]
Water was seen leaking from the front left of the machine while switched on. Upon investigation it was found to be dripping from the bottom of a device mounted inside near the back left corner. A water inlet enters the body of the laser cutter and is split, one hose goes to the offending device. This device appears to maybe be a water sensor of some sort.

=== Crooked Bed ===
[[File:Crooked cut bed.png|thumb|right|alt=Graphic depicting cut bed and laser range, cut bed is crooked, rotated slightly anti-clockwise|Crooked bed]]
The cut bed and guides are rotated slightly anti-clockwise, this means anything you align to the guide will be off a bit of what you may expect. For example, a straight horizontal line engraved on a piece aligned to the left edge guide will appear at a downward angle from left to right, on the piece. This also means if you start at (0, 0) and cut straight down ''you'll cut into the the guide'', oh no!

:'''Work around:''' There is a simple jig that's been cut and lives on the bed, it's a brown piece of MDF. If you want a square cut using the jig, place your piece in the top left corner against the jig and position the laser at x=21.9, y=0 (two presses of the right arrow on the controller).

=== Non-Level Bed ===
There appears to be a slight slope starting at (0, 0) from left to right the bed rises about 1mm over 10cm. This warrants further investigation, might be only near top left of cut bed, doesn't appear/shouldn't have dramatic affect on cuts.

=== Laser Pointer ===
Not to be confused with the powerful laser used to engrave and cut, this is a helpful little laser that points to ''where'' a cut will be made. It appears not to work at the moment.

== Operation Instructions ==
# First turn on the laser cutter control switch, located on the right side of the machine.
<gallery mode="packed" heights="200">
File:Laser_control_switch.jpg|Showing laser control switch on
</gallery>

=== Preparing Material ===
# Put [[LASER SAFE material]] on the bed
# Use the control pad arrow keys to move the laser head above your material. We want it above the material to properly set the bed height
# Once laser head above material, use the knob inside the laser cutter to move the bed up and down. The correct height is about 3/4" '''(UPDATE: use 17mm block)''' above your material. You can use the "laser focus height" tool as reference.

</gallery>

=== Turning on the laser and exhaust ===
# Turn on the exhaust fan by switching on the power strip on top of the laser cutter. You should hear the exhaust fan turn on. Also, switch on the air purifier on the desk.
# Enable the laser by turning on the laser switch on the left side of the machine, and turning the key on the front of the machine.

</gallery>

=== Preparing the file ===
[[File:Lightburn layer tips.png|thumb|LightBurn layer settings]]

The following steps should be done on the computer near the laser cutter, which has LightBurn installed on it.

# Open LightBurn on computer next to the laser cutter
# Import a vector file (svg, dxf, pdf, etc.), raster image, or create a design in LightBurn.
# Set the color of items to define how you want them cut or engraved, then double click the colors in the pane on the right to set the laser speed, power, and other features associated with that color. Black can be used to cut and red to etch, for instance. Use this chart to get a ballpark reference for speed and power settings: '''[[Big red laser cutter settings]]'''. It is recommended to do a "test cut" before cutting out a large file to be sure your speed and power settings are good.
# Select "absolute coordinates" to define the placement relative to the bed. Select "user origin" to set the placement on the bed manually. The device should be set to ttyUSB0, Ruida664GX.
# Once happy with design, click “Send”
# Enter a name (or just use default to override) and press enter.
# Wait for the file to send.

=== Running the laser ===
The following steps should be done using the control panel on the laser cutter itself.

# On the laser cutter control panel, press "File" to see available files.
# Scroll and press “Enter” to select a file.
# Set the origin if necessary.
# Press “Frame" to confirm placement. When you press this, the laser cutter head will trace around the max coordinates, to show you where your design will be cut.
# If the frame is correct press “Start”, and the laser will run.

=== Having Trouble Setting the Origin? ===
If you are using LightBurn to compose your project, be sure to use the setting "Current Position". 
Otherwise, LightBurn may override any origin you set at the laser cutter.

Setting the origin on the laser cutter is easy. 
On the front panel there are 4 arrow keys. You can use these to move the "head" around.
Pressing the "Origin" button sets that spot to be the origin of where cutting starts. Typically, this is the upper left
of the bounding rectangle around your artwork.
You may find that moving the "head" is much easier than moving the material placed on the bed!

== Cleaning ==
=== Lens & Mirrors ===
'''''Very carefully.''''' Clean the lens and mirrors monthly.

=== Exhaust Fan ===
If the exhaust fan is not working well, it might need to be cleaned.

To clean, detach the fan and base from the laser cutter. The green area circled in the below picture is where you need to get access, the '''intake'''.


<gallery mode="packed" heights="200">

== Other software ==
As mentioned, RDWorks can also be used. We haven't tried it yet but it seems it's a free download [https://www.thunderlaser.com/laser-download from here].

Some of the software (downloaded from the above link) is on the hard drive of wasp.local which is a desktop computer under the 3D printer desk, in a folder called ~/laser-backup/

[https://spaz.org/~jake/sudoroom/Big_red_laser_cutter/ The above software has also been downloaded and stored here]

It was setup with an IP address of 100.64.64.69 (by pressing buttons through the menu) but it had no ports open and then we just switched over to USB to the computer and it was working fine. The same software might work over ethernet but we didn't try.

== Trying other things ==
Andy is trying to find software to control the laser cutter. I can generate gcode instructions in Inkscape, but I don't know how to send them to the printer over USB.

I'm trying to install [https://laserweb.yurl.ch/|LaserWeb].

I ran the commands here: https://laserweb.yurl.ch/documentation/installation/36-install-raspberry-pi. But the server gave an error when started:

Big red laser cutter

2026-05-01T04:22:08Z

Arik: Add water leak issue

UPDATE: April 30, 2026
'''Out of order''' -- [[Big_red_laser_cutter#Water Leak|Water was seen leaking from the laser cutter!]]

== General Info ==
=== Introduction ===
The big red laser cutter is a no-name model using a [https://ruidacontroller.com/wp-content/uploads/2021/10/RDC644XGS-Control-System-V1.3-Manual.pdf Ruida 644XG control board]. Its bed dimensions are about 730mm wide by 500mm deep. It looks like a 100 W CO2 laser.

The Melbourne Makerspace has the same laser and have a [https://wiki.melbournemakerspace.org/Laser%20Cutter nicely written wiki page on it].

=== Maintenance ===
''To be performed '''monthly'''''
* Clean [[#Lens & Mirrors|lens & mirrors]]
As needed
* Clean [[#Exhaust Fan|exhaust fan]]
* Clean cutaway collection area under bed

=== Dangers ===
[[File:ISO 7010 W001.svg|frameless|right|upright=0.5]]
''Be aware:'' lasers are very dangerous! Review these [https://ehs.mit.edu/workplace-safety-program/laser-cutter-safety/ safety guidelines], and carry an appropriate level of fear of the laser at all times. Hazards include:

'''Fire hazard'''
[[File:ISO 7010 W021.svg|frameless|right|upright=0.5]]
Lasers create high heat, and can cause materials to catch on fire. Certain materials and types of designs (i.e very dense/small objects) are more prone to fire.

To minimize fire risk, remember to...
# Never leave laser unattended. Be prepared to respond promptly in case of fire. Familiarize yourself with where the fire extinguisher and water spray bottle are before using. You should never see a prolonged flame while using the laser cutter.
# If you see a candle sized flame for more than 3 seconds while cutting, stop the laser, check/adjust bed height, power/speed settings, or use a different material.

'''Respiratory Hazard'''
[[File:ISO 7010 W071.svg|frameless|right|upright=0.5]]
Laser cutters create fumes and small particulates.

To minimize respiratory hazards, remember to...
# Only cut and engrave [[LASER SAFE material]]. Some materials can emit toxic fumes when laser cut, and should never be used in the laser cutter!
# Always have the ventilation fan on while using the laser cutter, and for a few minutes after you are done. Even laser safe materials aren't good to breathe in.
# Check in with other people in the room before using the laser cutter to see if they are sensitive to fumes. Be accommodating!

'''Laser Hazard'''
[[File:ISO 7010 W004.svg|frameless|right|upright=0.5]]
To minimize laser exposure hazards, remember to..
# Never look directly at the laser beam. While wearing ''laser eye protection'', you may look at the point that the laser is cutting your material. However, you should NEVER look directly into a laser beam, even if wearing safety goggles.
# Never run the laser cutter while the lid is open.

'''"Help, I tripped the breaker!"'''

This is how to reset the [[breaker]] that the laser (and sewing/3dprinting/hardware corner) is on.

== Known Issues ==
Firstly, this thing is '''''great''''' and we love it, flaws and all! Here are some quirks that should be solved or worked around.

=== Water Leak ''ADDRESS BEFORE USING'' ===
[[File:Laser_cutter_leaking_device.jpeg|thumb|right|upright=1|Water leaks from this thing]]
Water was seen leaking from the front left of the machine while switched on. Upon investigation it was found to be dripping from the bottom of a device mounted inside near the back left corner. A water inlet enters the body of the laser cutter and is split, one hose goes to the offending device. This device appears to maybe be a water sensor of some sort.

=== Crooked Bed ===
[[File:Crooked cut bed.png|thumb|right|alt=Graphic depicting cut bed and laser range, cut bed is crooked, rotated slightly anti-clockwise|Crooked bed]]
The cut bed and guides are rotated slightly anti-clockwise, this means anything you align to the guide will be off a bit of what you may expect. For example, a straight horizontal line engraved on a piece aligned to the left edge guide will appear at a downward angle from left to right, on the piece. This also means if you start at (0, 0) and cut straight down ''you'll cut into the the guide'', oh no!

:'''Work around:''' There is a simple jig that's been cut and lives on the bed, it's a brown piece of MDF. If you want a square cut using the jig, place your piece in the top left corner against the jig and position the laser at x=21.9, y=0 (two presses of the right arrow on the controller).

=== Non-Level Bed ===
There appears to be a slight slope starting at (0, 0) from left to right the bed rises about 1mm over 10cm. This warrants further investigation, might be only near top left of cut bed, doesn't appear/shouldn't have dramatic affect on cuts.

=== Laser Pointer ===
Not to be confused with the powerful laser used to engrave and cut, this is a helpful little laser that points to ''where'' a cut will be made. It appears not to work at the moment.

== Operation Instructions ==
# First turn on the laser cutter control switch, located on the right side of the machine.
<gallery mode="packed" heights="200">
File:Laser_control_switch.jpg|Showing laser control switch on
</gallery>

=== Preparing Material ===
# Put [[LASER SAFE material]] on the bed
# Use the control pad arrow keys to move the laser head above your material. We want it above the material to properly set the bed height
# Once laser head above material, use the knob inside the laser cutter to move the bed up and down. The correct height is about 3/4" '''(UPDATE: use 17mm block)''' above your material. You can use the "laser focus height" tool as reference.

File:Laser_bed_correct_bed_height_with_tool.jpg|Showing correct bed height for laser with tool
</gallery>

=== Turning on the laser and exhaust ===
# Turn on the exhaust fan by switching on the power strip on top of the laser cutter. You should hear the exhaust fan turn on. Also, switch on the air purifier on the desk.
# Enable the laser by turning on the laser switch on the left side of the machine, and turning the key on the front of the machine.

</gallery>

=== Preparing the file ===
[[File:Lightburn layer tips.png|thumb|LightBurn layer settings]]

The following steps should be done on the computer near the laser cutter, which has LightBurn installed on it.

# Open LightBurn on computer next to the laser cutter
# Import a vector file (svg, dxf, pdf, etc.), raster image, or create a design in LightBurn.
# Set the color of items to define how you want them cut or engraved, then double click the colors in the pane on the right to set the laser speed, power, and other features associated with that color. Black can be used to cut and red to etch, for instance. Use this chart to get a ballpark reference for speed and power settings: '''[[Big red laser cutter settings]]'''. It is recommended to do a "test cut" before cutting out a large file to be sure your speed and power settings are good.
# Select "absolute coordinates" to define the placement relative to the bed. Select "user origin" to set the placement on the bed manually. The device should be set to ttyUSB0, Ruida664GX.
# Once happy with design, click “Send”
# Enter a name (or just use default to override) and press enter.
# Wait for the file to send.

=== Running the laser ===
The following steps should be done using the control panel on the laser cutter itself.

# On the laser cutter control panel, press "File" to see available files.
# Scroll and press “Enter” to select a file.
# Set the origin if necessary.
# Press “Frame" to confirm placement. When you press this, the laser cutter head will trace around the max coordinates, to show you where your design will be cut.
# If the frame is correct press “Start”, and the laser will run.

=== Having Trouble Setting the Origin? ===
If you are using LightBurn to compose your project, be sure to use the setting "Current Position". 
Otherwise, LightBurn may override any origin you set at the laser cutter.

Setting the origin on the laser cutter is easy. 
On the front panel there are 4 arrow keys. You can use these to move the "head" around.
Pressing the "Origin" button sets that spot to be the origin of where cutting starts. Typically, this is the upper left
of the bounding rectangle around your artwork.
You may find that moving the "head" is much easier than moving the material placed on the bed!

== Cleaning ==
=== Lens & Mirrors ===
'''''Very carefully.''''' Clean the lens and mirrors monthly.

=== Exhaust Fan ===
If the exhaust fan is not working well, it might need to be cleaned.

To clean, detach the fan and base from the laser cutter. The green area circled in the below picture is where you need to get access, the '''intake'''.


<gallery mode="packed" heights="200">

File:Laser_fan_dirty.jpg|Dirty exhaust fan '''intake''', ''an N95 mask is recommended'', use a vacuum and toothbrush/wire brush to clean.
File:Laser_fan_clean.jpg|Clean exhaust fan '''intake'''
</gallery>

== Other software ==
As mentioned, RDWorks can also be used. We haven't tried it yet but it seems it's a free download [https://www.thunderlaser.com/laser-download from here].

Some of the software (downloaded from the above link) is on the hard drive of wasp.local which is a desktop computer under the 3D printer desk, in a folder called ~/laser-backup/

[https://spaz.org/~jake/sudoroom/Big_red_laser_cutter/ The above software has also been downloaded and stored here]

It was setup with an IP address of 100.64.64.69 (by pressing buttons through the menu) but it had no ports open and then we just switched over to USB to the computer and it was working fine. The same software might work over ethernet but we didn't try.

== Trying other things ==
Andy is trying to find software to control the laser cutter. I can generate gcode instructions in Inkscape, but I don't know how to send them to the printer over USB.

I'm trying to install [https://laserweb.yurl.ch/|LaserWeb].

I ran the commands here: https://laserweb.yurl.ch/documentation/installation/36-install-raspberry-pi. But the server gave an error when started:

Tax history

2026-04-27T06:57:27Z

Arik: Update formatting

Organized by "tax year" below:

==2014==

Filed by Marc Juul Christoffersen (treasurer as of late 2014) and Matt Senate (on the board of directors at the time).

Our tax year ends on November 30th, so the filing dates for form 199N and form 990 is April 15th instead of the normal May 15th. We should really change this.

We e-filed 199N e-postcard, and we filed it on time at around 11 pm April 15th.

We filed form 990 using form990.org (a free service) at about 1:30 am April 16th and we had to email them an authorization form so they probably won't actually file it until start of business on April 16th. This means we will have filed at least one day late! We may have to pay a small fine for this, but we should receive information about this in the mail. The thing we had to email was "Form 8453-EO" which is an authorization to allow them to e-file. Marc Juul has both a copy of form 8453-EO and the login details for form990.org

* [[Media:Sudo room 2014 form 990 and supplements.pdf|Federal tax filing: Form 990 and supplements]]
* [[Media:Sudo room 2014 form 199N e-postcard.pdf|California state filing: 199N e-postcard]]

==2013==

===Applying for State Tax Exemption===
We received a notice from the State of California Franchise Tax Board, notifying us that (since we have yet to submit or complete our 501(c)3 application) we must fill out state form 3500 to convince California not to levy state taxes for last year, 2013.

I've filled out this form to the best of my knowledge so far, but it is incomplete. It needs some more attention. See attached:

[[Media:state_tax_form_3500_sudo_room.pdf|state_tax_form_3500_sudo_room.pdf]]
which should have saved my submitted values to many of the required fields. We need a few things:

# Review what I've already added (make sure dates and such are correct!)
# Complete the rest of the form to the best of our ability
# See if any lawyerly advice can help us ensure this goes smoothly
# Submit before Friday November 7 (30 days from October 9, 2014)

"Send us either your tax exempt letter, Form 3500, Form 3500A, or Form 100 with a copy of this letter within the next 30 days or we may issue a tax assessment based on available information. A penalty of 25% of the additional tax may be assessed for failure to provide information upon written request."

===Notes from submitting Taxes===
This is your treasurer ''notconfusing'' speaking. I'm a tax amateur, and you can too. On Apr 9th 2014, I went the Sustainable economies law center legal cafe to get some advice about how sudo should handle taxes. Here's what I learned:

#Tax day for corporations is the same as for people - April 15th.
#Every year we must file '''something'''. Even if you become a federal nonprofit, which we aren't yet, you have to tell the government that you don't owe anything. The basic things we '''need to file''' are:
##State Taxes: '''Form 199''', probably 199N
##Federales Taxes: '''Form 990''' Likely 990-EZ.
###You file 990-EZ as if you are a 501c3 even though we are not a 501c3, because we intend to be a 501c3 (that's the rules).
##Those forms are actually not due until '''May 15th'''.
##I will file these soon.
###Update: State taxes done - see [[Media:2013 sudo 199n confirmation.png|2013 sudo 199n confirmation.png]]
###Update: Federal taxes need to be mailed [[Media:Sudo_tax_federal_990.pdf|Sudo_tax_federal_990.pdf]]
###Our California EIN "Entity ID number" not federal EIN "Employer ID number" is 3617428.
#2013 was the year we switched from being "Eddan Katz" dba (doing business as) Sudo Room, to Sudo Room, the California non-profit public benefit corporation.
##Eddan is not claiming the income that was receieved, and it was all transfered to the new corporation.
##So the corporation will pay tax on it.
#Since we are not 501c3 yet the money "donated" to sudo room are not actually donations, i.e. not tax deductible.
#Corporations like us get 27 months after incorporation to file for 501c3. That puts our date at January 2016.
#The sudo EIN is 46-4109670

This is a visualization of 2013 finances. When debit exceeds credit we had a negative month. 'netcum' is net cummulative money aka total cash in da bank. So if debit exceeds netcum, then our month costed more than we have in the bank.

==Summary==
Sudo Room’s income is collected through a Stripe API implemented through a custom web application called Sudo-Humans ([https://github.com/sudoroom/sudo-humans|GitHub link]). This money passes into a bank account held by Omni Commons and banked with the Unified Financial Credit Union. Sudo Room’s obligations to Omni Commons are $2000. This obligation is transferred on a monthly basis by one of the members of the Omni Commons Finance working group.

We share an EIN with Omni Commons: 46-4109670. For more on Omni Commons finances, review summaries and disclosures on [https://www.guidestar.org/profile/46-4109670 Guide Star].

== Finance Working Group ==
Sudo Room's finances are managed by the Sudo Room finance working group and the OmniCommons [https://omnicommons.org/wiki/Finances_Working_Group finance working group]. The Sudo Room finance working group can be reached by emailing [mailto:finances@sudoroom.org finances@sudoroom.org].

Big red laser cutter

2026-04-27T02:44:48Z

Arik: Update and add warning signs

== General Info ==
=== Introduction ===
The big red laser cutter is a no-name model using a [https://ruidacontroller.com/wp-content/uploads/2021/10/RDC644XGS-Control-System-V1.3-Manual.pdf Ruida 644XG control board]. Its bed dimensions are about 730mm wide by 500mm deep. It looks like a 100 W CO2 laser.

The Melbourne Makerspace has the same laser and have a [https://wiki.melbournemakerspace.org/Laser%20Cutter nicely written wiki page on it].

=== Maintenance ===
''To be performed '''monthly'''''
* Clean [[#Lens & Mirrors|lens & mirrors]]
As needed
* Clean [[#Exhaust Fan|exhaust fan]]
* Clean cutaway collection area under bed

=== Dangers ===
[[File:ISO 7010 W001.svg|frameless|right|upright=0.5]]
''Be aware:'' lasers are very dangerous! Review these [https://ehs.mit.edu/workplace-safety-program/laser-cutter-safety/ safety guidelines], and carry an appropriate level of fear of the laser at all times. Hazards include:

'''Fire hazard'''
[[File:ISO 7010 W021.svg|frameless|right|upright=0.5]]
Lasers create high heat, and can cause materials to catch on fire. Certain materials and types of designs (i.e very dense/small objects) are more prone to fire.

To minimize fire risk, remember to...
# Never leave laser unattended. Be prepared to respond promptly in case of fire. Familiarize yourself with where the fire extinguisher and water spray bottle are before using. You should never see a prolonged flame while using the laser cutter.
# If you see a candle sized flame for more than 3 seconds while cutting, stop the laser, check/adjust bed height, power/speed settings, or use a different material.

'''Respiratory Hazard'''
[[File:ISO 7010 W071.svg|frameless|right|upright=0.5]]
Laser cutters create fumes and small particulates.

To minimize respiratory hazards, remember to...
# Only cut and engrave [[LASER SAFE material]]. Some materials can emit toxic fumes when laser cut, and should never be used in the laser cutter!
# Always have the ventilation fan on while using the laser cutter, and for a few minutes after you are done. Even laser safe materials aren't good to breathe in.
# Check in with other people in the room before using the laser cutter to see if they are sensitive to fumes. Be accommodating!

'''Laser Hazard'''
[[File:ISO 7010 W004.svg|frameless|right|upright=0.5]]
To minimize laser exposure hazards, remember to..
# Never look directly at the laser beam. While wearing ''laser eye protection'', you may look at the point that the laser is cutting your material. However, you should NEVER look directly into a laser beam, even if wearing safety goggles.
# Never run the laser cutter while the lid is open.

'''"Help, I tripped the breaker!"'''

This is how to reset the [[breaker]] that the laser (and sewing/3dprinting/hardware corner) is on.

== Known Issues ==
Firstly, this thing is '''''great''''' and we love it, flaws and all! Here are some quirks that should be solved or worked around.

=== Crooked Bed ===
[[File:Crooked cut bed.png|thumb|right|alt=Graphic depicting cut bed and laser range, cut bed is crooked, rotated slightly anti-clockwise|Crooked bed]]
The cut bed and guides are rotated slightly anti-clockwise, this means anything you align to the guide will be off a bit of what you may expect. For example, a straight horizontal line engraved on a piece aligned to the left edge guide will appear at a downward angle from left to right, on the piece. This also means if you start at (0, 0) and cut straight down ''you'll cut into the the guide'', oh no!

:'''Work around:''' There is a simple jig that's been cut and lives on the bed, it's a brown piece of MDF. If you want a square cut using the jig, place your piece in the top left corner against the jig and position the laser at x=21.9, y=0 (two presses of the right arrow on the controller).

=== Non-Level Bed ===
There appears to be a slight slope starting at (0, 0) from left to right the bed rises about 1mm over 10cm. This warrants further investigation, might be only near top left of cut bed, doesn't appear/shouldn't have dramatic affect on cuts.

=== Laser Pointer ===
Not to be confused with the powerful laser used to engrave and cut, this is a helpful little laser that points to ''where'' a cut will be made. It appears not to work at the moment.

== Operation Instructions ==
# First turn on the laser cutter control switch, located on the right side of the machine.
<gallery mode="packed" heights="200">
File:Laser_control_switch.jpg|Showing laser control switch on
</gallery>

=== Preparing Material ===
# Put [[LASER SAFE material]] on the bed
# Use the control pad arrow keys to move the laser head above your material. We want it above the material to properly set the bed height
# Once laser head above material, use the knob inside the laser cutter to move the bed up and down. The correct height is about 3/4" '''(UPDATE: use 17mm block)''' above your material. You can use the "laser focus height" tool as reference.

</gallery>

=== Turning on the laser and exhaust ===
# Turn on the exhaust fan by switching on the power strip on top of the laser cutter. You should hear the exhaust fan turn on. Also, switch on the air purifier on the desk.
# Enable the laser by turning on the laser switch on the left side of the machine, and turning the key on the front of the machine.

</gallery>

=== Preparing the file ===
[[File:Lightburn layer tips.png|thumb|LightBurn layer settings]]

The following steps should be done on the computer near the laser cutter, which has LightBurn installed on it.

# Open LightBurn on computer next to the laser cutter
# Import a vector file (svg, dxf, pdf, etc.), raster image, or create a design in LightBurn.
# Set the color of items to define how you want them cut or engraved, then double click the colors in the pane on the right to set the laser speed, power, and other features associated with that color. Black can be used to cut and red to etch, for instance. Use this chart to get a ballpark reference for speed and power settings: '''[[Big red laser cutter settings]]'''. It is recommended to do a "test cut" before cutting out a large file to be sure your speed and power settings are good.
# Select "absolute coordinates" to define the placement relative to the bed. Select "user origin" to set the placement on the bed manually. The device should be set to ttyUSB0, Ruida664GX.
# Once happy with design, click “Send”
# Enter a name (or just use default to override) and press enter.
# Wait for the file to send.

=== Running the laser ===
The following steps should be done using the control panel on the laser cutter itself.

# On the laser cutter control panel, press "File" to see available files.
# Scroll and press “Enter” to select a file.
# Set the origin if necessary.
# Press “Frame" to confirm placement. When you press this, the laser cutter head will trace around the max coordinates, to show you where your design will be cut.
# If the frame is correct press “Start”, and the laser will run.

=== Having Trouble Setting the Origin? ===
If you are using LightBurn to compose your project, be sure to use the setting "Current Position". 
Otherwise, LightBurn may override any origin you set at the laser cutter.

Setting the origin on the laser cutter is easy. 
On the front panel there are 4 arrow keys. You can use these to move the "head" around.
Pressing the "Origin" button sets that spot to be the origin of where cutting starts. Typically, this is the upper left
of the bounding rectangle around your artwork.
You may find that moving the "head" is much easier than moving the material placed on the bed!

== Cleaning ==
=== Lens & Mirrors ===
'''''Very carefully.''''' Clean the lens and mirrors monthly.

=== Exhaust Fan ===
If the exhaust fan is not working well, it might need to be cleaned.

To clean, detach the fan and base from the laser cutter. The green area circled in the below picture is where you need to get access, the '''intake'''.


<gallery mode="packed" heights="200">

== Other software ==
As mentioned, RDWorks can also be used. We haven't tried it yet but it seems it's a free download [https://www.thunderlaser.com/laser-download from here].

Some of the software (downloaded from the above link) is on the hard drive of wasp.local which is a desktop computer under the 3D printer desk, in a folder called ~/laser-backup/

[https://spaz.org/~jake/sudoroom/Big_red_laser_cutter/ The above software has also been downloaded and stored here]

It was setup with an IP address of 100.64.64.69 (by pressing buttons through the menu) but it had no ports open and then we just switched over to USB to the computer and it was working fine. The same software might work over ethernet but we didn't try.

== Trying other things ==
Andy is trying to find software to control the laser cutter. I can generate gcode instructions in Inkscape, but I don't know how to send them to the printer over USB.

I'm trying to install [https://laserweb.yurl.ch/|LaserWeb].

I ran the commands here: https://laserweb.yurl.ch/documentation/installation/36-install-raspberry-pi. But the server gave an error when started:

== Stuff made on the big red laser cutter ==

* I cut some 1/4" clear plastic suspected to be acrylic. Used 0.5mm/sec 100% / 40% power. It cut all the way through but the edge was rough.

== Stuff seen around the space ==


== Ventilation ducting ==

=== History ===
A plastic adapter was 3D printed to connect the 6" outlet of the exhaust fan to the 8" flexible duct leading to the roof hole:
{| class="wikitable mw-collapsible mw-collapsed"
|+ class="nowrap" | SCAD instructions
|
<nowiki>
laserduct.scad
THICKNESS=1.5*25.4;
ID=5.75*25.4;
ID_LIP=ID-(0.25*25.4);
ID_LIP_THICK=0.2*25.4;
OD=7.75*25.4;
OD_LIP=OD+0.2*25.4;
OD_LIP_THICK=0.2*25.4;
difference() {
color("BLUE") cylinder(d1=OD_LIP, d2=OD, h=THICKNESS, $fn=100);
{
translate([0,0,ID_LIP_THICK]) cylinder(d=ID, h=THICKNESS, $fn=100);
translate([0,0,-0.5]) cylinder(d=ID_LIP, h=THICKNESS, $fn=100);
}
}</nowiki>
|}

Also the duct/roof interface was improved and a new stand was made for the extractor fan. Yay for milk crates!
