It's easy enough in MACH3 to enable machine coordinates and then move to approximately where the limit switches would be and zero the axis. At that point switch out of machine coordinates and move to say the corner of the vise, set the zeros for the current G5x_ state and it's as if you've done a mechanical home with the majority of the machine work envelope available. In MACH3 the rule is that limit switches must not be assigned in the inputs dialog in order for this to work. How is this done in LinuxCNC? My desktop testing bits and pieces doesn't have limit switches and at the moment is wired with the limit inputs to ground to simulate closed switches. The reason would be if I executed the end of project sequence created by Fusion360 M9 G28 G91 Z0. G90 G28 G91 X0. Y0. G90 M30
Just curious. I'm a big believer in limit and home switches. John "ELS!
