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

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.
