@wgantt Actually, it was for Z. But it was when I attempted to home, I was getting Alarm 8. It was likely jogging too fast before reaching the switch.

Which error or alarm are you getting? FYI, there’s a difference between the Alarm codes and Error codes of the same number. So make sure you specify Alarm or Error.
