I’m at a loss. After changing material and shutting down, the M300 throws the error code #032
“Check the main extruder cable and restart the printer”, and refuses to boot.
I unplugged the main extruder cable and plugged it back in, to no avail.
How do I even start looking what the culprit is, before I order the wrong part…
One thing I noticed is that it took abnormally long for the extruder to heat up to change the material. But before I replace the heating element, any other possible culprits?
Thanks in advance!
Update 1: I found it to be the thermocouple.
at the two cables coming out of the thermocouple, I measure a resistance of 18 Ohm, but at the connector, there’s an open circuit. There must be a fracture somewhere in one of the cables, or in the connector itself.
I’ll replace the heater and thermocouple, and see if this fixes it.
Update 2: I replaced the heater and thermocouple unit, the printer works again! Also, the continuity test on the extruder cable indicated no faults in the cable itself, which makes sense because the fault didn’t lie there. Thanks for the help.
