I am struggling with an issue revolving around my override switch.  When I hit a hard stop, the switch dims and becomes unavailable, the only thing I can do to jog off is remove the switch physically!  I will include a link to a you tube video and a screenshot to my pokeys home/limit switch page, appreciate any help or advice.  Running Mach 4 on a pokeys 57cnc board and right on the edge of being in over my head
