so i tried to edit the wiki page for the brother printer, here:
https://sudoroom.org/wiki/Brother_HL-2270DW
i wanted to put in a prominent thing called "HELP! how do i stop it
printing stuff nobody wants?" and i sortof did, but i didn't know what the
proper instructions were.
the other day, it was spitting out a million copies of something that
someone tried to print earlier, while the network was down.
we tried turning off the printer and waiting, but it would just start
right back up …
[View More]when we turned it back on - printing on both sides of nice
blank white paper.
I went to the printer's control page at http://192.168.1.8 but it wouldn't
allow me to do anything with the user login, and the admin login was
unknown so i couldn't try that.
then i emptied the print spool on the computer that the jobs had come
from, with lprm - to cancel all jobs (and there were several) but it
didn't seem to have any effect.
this is the nightmare that comes with WIRELESS networked printers. that
is, if you think printing on both sides of papers until the printer
decides it's done (how many times did the person try to print before
giving up?) is a nightmare.
i wish printers had an "expire jobs" setting so that they wouldn't try to
print stale jobs from hours ago.
so... can someone put instructions on the wiki on cancelling print jobs?
thank you

wrought brought in the replacement resistor sent by LulzBot, which came
with a couple of crimp thingies to make the connection. I used them
(although i was not impressed with their crimpiness and i worry they might
fail) and i put heatshrink over them (and mylar tape on one) to insulate
them.
i installed the new resistor with aluminum foil as a spacer, which made it
fit very snugly. according to lulzbot nothing is needed as a spacer,
which I think is ridiculous. with no spacer, the …
[View More]resistor is loose in the
hole, which would explain why it burned out.
i uploaded the "new" firmware to the machine according to the instructions
from lulzbot. my arduino program told me that the upload failed, but the
LCD of the machine says it has the latest firmware, and talking to it over
serial it says that the firmware was compiled tonight, so apparently the
upload didn't fail.
it's printing an octopus now, in black, from the giant spool installed in
the wall above the desk. It's about 3mm high now and should finish
nicely. the TAZ is fixed.

Subject: [sudo-info] TAZ 3 Service Bulletin 24V firmware
To: info(a)sudoroom.org
Hello TAZ user,
We have received reports of hot end failures from a small number of TAZ
users with 24v systems. This includes the TAZ 3 model and TAZ 1 or 2
versions that have been user upgraded to 24V volts. These failures are
characterized by a sudden failure of the hot end.
…
[View More]After a thorough investigation, we have determined that in some cases the
default 24v firmware settings can cause the hot end heater resistor to fail
over time. We have tested and verified a software-based solution. We are
recommending that all TAZ 3 users upgrade the Marlin firmware with the
update instructions found here:
ohai-kit.alephobjects.com/project/marlin-resistor-update/<https://phplist.alephobjects.com/lists/lt.php?id=f0oBHwYaUwsA>

please contact customer support at support(a)lulzbot.com or 1-970-377-1111

so i spent all evening (and some of last night) to finally spool up the
gigantic pile of black filament for the TAZ 3D printer.
i finally got it hung from the wall with a dust cover over it and ready to
feed smoothly into the printer, and then i discovered that the heating
element in its extruder head is dead.
oh well.
so, we need a new resistor to go in there. I don't know what the original
spec is, but since the whole thing runs on 24VDC and assuming 24 watts of
heat, that would be a …
[View More]24 ohm resistor or so.
Is someone other than me interested in contacting Lulzbot and asking
whether they want to send us a new resistor, or if they can tell us what
part number of resistor we should get as a replacement?
-jake
P.S. yes i tested the resistor and it's dead, infinite ohms, it's burned
out. When we get a replacement we can glue it in there better than they
apparently did. If the glue goes bad it dies.
