When homing, I even hit the switch (brand new switch) manually when the gantry was moving to home position, Repetier is getting the signal that it is High but gantry still continues moving.. I changed the switch out thinking it was just a bad switch, didnt help, reinstalled the firmware thinking maybe it got corrupt somehow, that didnt help.. Im beginning to think it may be a problem other then Repeteir, Im thinking maybe I have a short in a wire someplace.. Going to rewire the entire printer from scratch a bit better this time.....
