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?!

Gotta ask…are you sure the switch hasn’t failed? Looks like the switch has failed “closed” - check and be sure it actually works?

As @mikep noted it sounds as if the switch has failed — see if your board has lights for the switches — if so, the appropriate light should light when the switch is closed.

You were dead-on; z-axis limit switch is dead.
My frustration clouded my troubleshooting.
