My mini’s extruder is not heating up. I took the case off and I’m confirmed the following:
- All 3 fuses are OK
The light on the board comes on when I tell Cura to turn on the extruder heater
The voltage coming out of the board on the extruder connector is about 20V (I think it is PWM so hard to get an exact reading on a multimeter. I didn’t put my scope on it).
The resistance of the extruder wire is about 100kohms (not sure what this should be).
Any suggestions on what to check next?
