It started today. After touching my touchoff plate, Z axis DRO always shows +269 in stead of 0. I mean in stead of 6.5 I set it to move up 6.5 after touching the plate. Auto zero is checked in config/home and limits.
I was playing with the button "set variable position" and "go to variable position" yesterday to see how it works.
Maybe this is the reason, but how can I fix that?
