Confusing heater failtures
-
Hi *,
I have some strange issues with my hotend heater.
(Duet 2 mini 5+ Toolboard 1.1 Fw: 3.2.2)The print started right after the green line:
And stopped left on the blue line. I resetted the heater turned it back on, so you can see a almost flat line, till I resumes the print what you can see at the very right end.
I checked the thermistor and the wiring a couple of times now and I can not find any short or short to ground. Should I replace the thermistor and hope the best or does anybody have a better idea what may be wrong here?
Cheers, Chriss

@chriss This issue can occur:
- Bad Crimp connection
- Cable break
- Bad connection to the thermistor
- Bad Thermistor
- Bad soldering on the duet board
So check these five options which can fix your Problem

@chriss my guess is that your thermistor is picking up interference from your stepper motor. Maybe see if you get the same issue just manually extruding?
Best solution is to try and route them separately, but you could also use shielded and/or twisted pair cables.
