As the subject states, Z homes fine, Y homes fine then X trips the home switch and keeps going till the limit stops it.
I did a clean install of windows 10 on my cnc pc and updated CNC12 from 5.08 to 5.30 while I was at it. Re-entered the wizard settings and copied in my previously working cncm.hom file and started encountering this issue. X,Y,Z are connected to a single "home all" input so I can't understand why Z and Y work but X doesn't. I ran the home program in single block with the homing speed lowered to 1.0 ipm and can clearly see the home switch trip well before the limit, which I measured at 0.170" separation. What am I missing here?

You are trying to home X in the plus direction, but you have only designated a home switch input for X minus.

I knew it had to be something simple I was missing! Thanks!
