Help - print repeatedly paused for extruder over temp

Zortrax M200 Tips & Tricks

Hi … I have a M200 that has developed a fault where it will only run up to a couple of hours before pausing a print due to extruded over temp

I’ve fitted a new bed, new v2 hot end, new heater/thermocouple and no change

Tried HIPs and Iltramid material on different print … same result.

Could be a problem with the little PCB on top of the extruder motor. Or a cable. Or the motherboard.

Thanks Julia - ive ordered a replacement PCB and will try this next
