I can't seem to figure out what has happened to my Z axis. My X and Y are fine, but for some reason my Z lifts off the table way too high over the material. I reinstalled Mach3 thinkiking something was not right, butit still has the issue. Anyone ever have this before? .......thank you

Check the parameters you have for the Z axis for motor steps per unit.
