having same problem, at first it would hit home switch, stop for a nano sec. then keep going, so reread manual, I had N.O. switches, manual calls for N.C., So I replaced them with N.C. Then it would hit home, then try to come off, and before it could move, the limit would trigger, so I disabled the limit, then it would hit home try to come off, and just keep going. Using G28.1 X 0 axes hits home and stops. Doesn't back off. Using G28.1 x .500 axes rapid movement to .500 then creeps to home and stops, doesn't back off. Any help with this? Thanks, Jim
