I think the software allows going the opposite way or only in jog
mode when an over travel switch is tripped. Also, a momentary
override button could be used to allow one to bypass the overtravel
switch.

The question becomes one of how many switches are enough ? if you
put in G00 x90.01 instead of G00 X9.001 you are headded for a
problem. if you just kill that axis, the other axis and program will
keep going.

A wind down to next program line would be a good option. Let the
unit fail in posistion so to speak.
