[sudo-discuss] lulzbot TAZ 3d printer is dead

[Jake]

if the TAZ we has now has the 2.0 schnozzle then it might use the 4.7 ohm 
resistor as seen here:
http://www.lulzbot.com/products/heat-resistor-47-ohm

of course the printer will work with a different resistor as long as it 
provides enough heat to print.  Worst case we have to insert M220 S50 to 
slow it down to half speed printing until we get a better resistor...

what value resistors do you have?  any special glue?
