Up box+ stepper motor not working

Post by Jclark0907 » Thu Mar 28, 2019 11:07 am

My stepper motor quit working yesterday. When I turn it on and try to extrude its like there is no power to the motor, but fans work. I have two machines, I swapped out the the whole head and ribbon cable between the two machines and it works fine on the 2nd one.

erm, sounds like you need a new extruder then?
Is it under warranty? If not they're easily available as a spare part.

Have you unplugged the extruder while the machine is initialized? So your printer isn't sending power to the extruder motor?

Stepper motor driver chips can be killed if you unplug the motor while it is powered on. If this is the case you'll need to replace the main board in the back of the printer, or you will need to do a board repair (replace driver chip/use a breakout board with new driver). Always take care to power down the machine before unplugging the extruder.
