Hi !
I've bought a Prusa i3 Steel from Orballo with RAMPS 1.4SB and DRV8825. I've got a problem with long print : extruder motor stops working at midprint. I've already had missed steps on XYZ axis which was solved with a 12v fan on RAMPS and trimpot adjustement.
This time I've tried to fixed the extruder problem with a trimpot adjustement too but, nothing happened and moreover, the extruder step motor doesn't work anymore.
I've tried to :
- plug the extruder wires on axis motor which does not turn too
- plug the extruder motor on axis wires and it works
- exchange the DRV8825 on RAMPS (I've got one spare) but it's the same
What can it be ?
Thank you,
Sébastien
