I was printing an object and it started to drag so I stopped it.
Went to move the Z-axis up so I could clear the bed and Z-axis would not budge. I switched the printer off and manually turned the motors to get the Z up. Cleared the bed, switched on and homed the printer. When it came to home the Z, BLTouch deployed and then nothing. Motors will not turn.
Things I tried:
- Recompiled the firmware (Marlin 2.0.x)
- Different motors - Motors were free from the printer, just resting on a desk so I know it's not binding or anything.
- Swapped stepper driver with a known working one.
Info about the printer:
- SKR1.4 Turbo board
- TMC2208 Steppers
- Octopi to control the printer.
