In the middle of a print, my extruder stopped feeding. Tested individually, the stepper, stepper driver, and wiring all test good. With an Oscope, I'm not seeing pulses on the step pin of E0. E1 has never been used, but I switched to and added a fake extruder in setup E1 and not getting pulses there either. No obvious damage to the board.

I'm out of ideas to troubleshoot.

Hi! You can interchange the pin definitions of E0 and E1 pin.
