I just converted my CNC router from WinCNC to CandCNC and Mach3. While most of the Mach3 settings are superior to WinCNC, and there is much better control, I have found one serious deficiency. WinCNC has a button labeled "Touch Top". When selected, the Z axis goes down until it touches a touchpad (I got the Mach3 software to do that), then it stops, deducts the thickness of the touchpad (0.498"), sets Z to zero, then raises the Z axis to .750".
So far, I have gotten Mach3 to lower the Z axis until the tool touches the touchpad, but at that point is stops. I have to manually raise the head, remove the touchpad, manually enter 'Z-.498', reset Z to 0, then raise the head. I know a macro can be made and assigned to one of the screen buttons (Load Material , for isntance, is useless to me ...), but I don't want to reinvent the wheel if there is already something out there that will do a similar job. Does anyone have anything like that, or do I need to start studying VB again (I used it years ago, but hoped I would never have to again ...)
Thanks
