Mk3 initializing issue

MY printer is doing this now

how can i fix it?? not sure how to fix it.

Looks like it’s not hitting the limit switch there at the top. Maybe the switch needs to be rotated or more easily actuated.

I just had a similar thing happen on my X axis. The limit switch was making contact, but not shutting off. I checked the switch itself with a continuity tester, everything was fine. Checked the wiring, again fine.
I ultimately ended up resetting the CPU via the CPU Utility Tool, simply reset it.

Give that a shot.
