[sudo-prints] TAZ 3d printer fixed

[Jake]

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 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.
