Probe Screen - Interface

Looks like you are using Verse probe routines.
This is a third party library so we don't have docs for it.

If you run linuxcnc from a terminal, you might see more info to give a clue about what is happening. please post it.

Could you post your config files.

I don't know much about it but maybe have a look at this : forum.linuxcnc.org/49-basic-configuration/29187-work-with-probe

And also on github: github.com/verser-git/probe_screen_v2
