I have the PP for ArtCam that allows for the TC (manual of course). It uses M0 instead of M6 (not sure what the final difference is). What I am trying to do is get the machine to return to "home" for the tool change, and then pickup where it left off. I think that I understand that the G28 and G30 will return the machine to home. The reason I want to go to home is to ensue that I get the same tool height (a couple of the bits are longer than the others)

The questions are...Where would I add the line in the PP? Will G28 or G30 achieve what I want? I have included the PP just in case it makes it any easier.

A big Thanks in advance.

Please bare with me, as I am new to this. I also noticed that "settings" in Mach has a tool change location/coordinates. Is that where the M6 sends the machine to? Would I be further ahead to just substitute the M0 with M6?
