My EARLY SO3 running GRBL 4.1 and CM4 stopped homing properly today with ZERO changes.
The Z axis moves up a few MM, stops briefly, then moves up a few more MM rapidly, then stops. I get multiple errors in CM:
- Limit Switch Error Z
- GRBL ERROR: Homing Failed, pull off didn’t clear
- Homing Cycle Failed
If it gets to the Z axis limit switch it bounces off of it repeatedly.
I have checked everything I can think of with no success.
Anyone have any ideas?!
