I have looked at several posts for tool zero macros etc. tried several but with no success. I obviously do not unerstand how htis works. One I was really interested in was a simple copper plate of a known thicknedd two leads one to the controller and the other to the tool with a cli[ when the tool touched the copper it would auto register a prefixed dimension of the copper plate. I tried many ways to make this work I needf help this would save me a lot of time if I can get it to work.
