<big>'''''See [[O:55]] for documentation on use of the CNC mill inside sudo room''''' </big>
'''CNC Mill''' or '''computer numerical controlled milling device''' is used for automatically milling or cutting away at materials like wood, plastic, or softer metals such as aluminum based on a 3D computer model.


<big>'''''See [[O:55]] for documentation on use of the CNC mill inside sudo room''''' </big>
Akin to a [[Printing|3D Printer]], the CNC provides the ability to work with objects in x, y, and z dimensions. However, it provides ''subtractive'' manufacturing, rather than ''additive''.


sorry i dont know enough wiki-fu to make it prettier than that -jake
The sudo room sign by the intercom at the old 22nd st entrance was milled on such a machine!

The Noisebridge wiki contains much knowledge about using CNC mills for example '''TO MILL CIRCUITBOARDS''':

We have a real CNC Mill as of January 2015.  It belongs to Pam and is on-loan.
It is a [[myDIYCNC]] [http://www.mydiycnc.com/project%20overview link] cnc thing
 
Problems:  For some reason, LinuxCNC thinks "home" is at 5.5", 0", 0" which is not where I would home it.  I put sharpie marks to indicate the center of travel for X and Y, which is 6.0",3.5".  I set the proper numbers in the configuration but it doesn't do what it should.  Whatever.
 
You need to boot the computer to the LINUXCNC operating system, not the Ubuntu 14.04 installed by Big Ed

The USB adaptor it came with is total garbage, and the software offered by "my DIY CNC" is proprietary, so it is plugged into the parallel port of a desktop computer instead, and we are using LinuxCNC software as seen here: http://www.linuxcnc.org/


== Sudoroom CNC machine instructions==
We'll be learning how to use this and adding more documentation here.


it is composed of a few components:
[[File:Jake using the new CNC machine.JPG|550px|J using our new CNC - isn't it cute? Hope we can get more folks started on machining]]


- an internet connected desktop windows PC that runs special software: mach3 (icon on desktop)
== The Past ==


- a hacked engraver that does the milling
* [[JacksMill]] In the past jack lent us his CNC mill which we used to cut wood. It was at the old SudoRoom. It is no longer at the SudoRoom but it left behind some awesome memories.


- a stepper driver that sits between the PC and the engraver and communicates via parallel port


mach3 only accepts gcode. you can either use your own gcode or use the program on the PC called CamBam to generate the gcode.

until we make better tutorials for CamBam please only use the CNC if you can get a CamBam tutorial from someone.
