Re: Extruder not working
Posted: Sun May 26, 2019 3:52 am
My Prusa i3 Pro B's extruder stopped working.
I tested the motor and cable on another slot, they work.
I swapped the A4988 with another one, it works.
So the problem comes from the board.
I moved the cable as well as the A4988 to the unused 4th slot. I swapped the three pin numbers (E*_STEP_PIN, E*_DIR_PIN, E*_ENABLE_PIN) under "Ultimaker Pin Assignment" in pins.h, then flashed the firmware.
It still doesn't work.
Any ideas?
Thank you
