General Mach Discussion / Re: Home and limits stopped working

XML seems fine from a quick glance, except I would have expected NC to be set Normally High, but maybe the G540 inverts them?
Even so then it would show limits hit until you pressed them so looks like its not the problem as you dont get any signs of limit activity.
Best bet is to remove the cable from the computer and test directly on the port by shorting out pin 13 to a Gnd pin and see if the limits LEDs change, if they do then its a problem with either cable or G540, if not its then it would seem the port is the problem.
