NO the end move is NOT a fault and it will record the endpoint same as a trip. It is JUST a safety built into the G31mode to stop a runaway situation. THe function is acutally USED in some probing routines.
Yes the G31 has overun. It is the amount of movement that mach requires to bring the axis to a controlled stop AND the amount of overtravel in your probe.(distance from tip contact until switch trips).
THe problem you will find IS that MACH does not have a protected move MODE.(;-) Like other commercial controllers have.
You could do it with a brain to monitor the trip led and do a STOP BUT you would have to switch it off with a Mcode before any G31 call then switch it back on with a Mcode before the next go/g1moves. AND then there is NO garranty that you could stop the move before it damaged the tip/probe. It would depend on how much over travel your probe could take before it damaged something.
