Odd thermistor faults.

wdenker

@phaedrux no but my infrared thermometer shows it is accurate.

@phaedrux here is after a pause and resume and MCU showing 38c and infrared confirms 38c

I think the MCU temp is a red herring.

The graph seems more like noise or interference. Or failing thermistor.

wdenker

@phaedrux thermistor was just replaced. I can replace again and see if I still have issues I suppose.

Phaedrux

Does any component on the board seem to be getting abnormally hot?

wdenker

@phaedrux extruder motor is.

@wdenker my guess is it's noise from nearby wiring such as running next to a motor cable

wdenker

@jay_s_uk I've got 8 other printers wired and running the same way. Only difference is this one is duet 3 instead of duet wifi 2.

Phaedrux

@phaedrux extruder motor is.

I mean on the board itself.

wdenker

@phaedrux no one including the expansion board where the thermistor is plugged in. Both good temps now.
