I have a new shopdroid, with a G540 controller and Mach3 w/Lazycam. I have X and Y running well and will run G-code, but I haven't integrated my plasma cutter yet. I am now trying to setup my touch and go for my z axis. This is very confusing. I have installed the Mach XML file and altered it to my config, but this is all so new to me I am having a hard time. My z home touch switch is wired to the input and i can see it activated from my diagnostic page, but does not touch and back off as I would like. Any HELP Would be GREAT!
