Hi everyone! I have an Anet A8 clone, a P802MA, an I've been having trouble with the extruder motor skipping while printing PETG.
For the most part its fine, but throughout the print it will skip steps at random during fast perimeters and such.
The stepper models 17hd40005-22b, and what I've had to do so far is pump up the driver voltage to increase the torque. I'm wondering if anyone has experience with what kinda of values I can use...
The factory voltage that was set is 0.826V on the driver, and I have it at 0.96V in order to get minimal skipping. Understandably, the motor now gets pretty hot, so I mounted a small fan/heatsink on it to keep it cool.
Am I ok running it like this? is there something else I'm missing that may be causing the problem??
other details:
Overture brand yellow PETG, extruder at 240C
Max speed is 60mm/s on the prints
Doesn't seem to be much back tension on the filament
