So all of the sudden my auto zero z button is not there I didn't unplug my touch sensor (I have an avid cnc 60x120)

I'm very new so any help is appreciated

thx in advance!

Hi,
look at the screen set being used, displayed in the lower right of Machs current screen.

I suspect that somehow you have corrupted your original screenset so Mach has reverted to wxMach.set.
wxMach.set is a cut down screen set which is not editable in the regular manner. It was made in Machs early days
for testing purposes and only occasionally sees the light of day.
