Hardware change is needed. You need a amplifier/signal conditioner, like the AD595.

now i wish they sell "screw tube" (heat barrel) for around $5... if not... my diy plan is unchanged.

Beware.. this one use a thermocouple and not the thermistor.. so you need to change the firmware to use the good heat table..

i put this in the francophone section, but i think it can be a good idea to put it here also..

for information, i bought this hot end for 19$.. you can put it on the original "screw tube'..

it use standard ultimaker/makerbot nozzle end.. (i choose a 0.4mm..)

the thermistor is a standard 100k like the original one... i put in place ... same for the head heater.. (strandard 12v heater)

it's well build... but we lost 2 or 3 cm... but it think you can cut the original "screw tube" to take it back..

you can found this head on all chinese import site like dealextreme/ goodluckbuy/ aliexpress ...

mine come from here :

it took 23 days for quebec/canada

i think it's a good choice if you didn't want to change all your extruder, but just changed a broken original nichrome..
