Strange problem on my new LR3 build with SKR controller. While homing, sometimes Marlin homes X, Y and Z perfectly but sometimes one stepper continues to to drive after the limit switch triggers. And sometimes it will overstep for a few seconds and then stop and then the home is complete. Other times the overstepping continues until I reset the box. It’s somewhat random which stepper will do this as it’s occurred on both Y steppers, both Z steppers and on the X stepper. There is an LED on the SKR board that lights when the limit switch triggers.
I have ruled out:
- Wiring problems because I can monitor the trigger LED on the SKR board and it lights appropriately when the switch triggers.
- Swapped limit switch inputs because I have homed everything properly several times.
I’m out of ideas. Thanks in advance as any help would be appreciated.
