Extruder skipping
Ater many hours of printing i have started having problems with the extruder motor skipping. It cannot extrude at the rates it used to be able to. Last time i printed i had to limit volumetric flowrate to 5mm^3/s and it would still skip. I have tried the following:
1) Tried to swap the stepper driver to one from another motor.
2) Tried to use another socked with same and swapped driver
3) Replaced the extruder and stepper motor. (I had an LGX lite and am now using an orbiter 2.0)
4) Made sure that the config uses the 0.85A that the manual for the Orbiter specifies.
5) Replaced all cables from the board to the extruder
6) Reflashed firmware and reinstalled RatOS on a different Pi
I know its not clogged nozzle either, i can remove the nozzle entirely and still have it skip. I can hold back the filament with relative ease and it becomes easier the longer it tries to extrude.
I'm wondering if its the mainboard or the power supply....when i measure the power into the board from the PSU its all 24V. I'm at the end of my rope. Please help 😅
