Limit switches and Mach3

[JAZZCNC]

Your lucky you had Delrin nuts has 2mm pitch screw gives very high torque and if it had been Brass nut then would have probably done more damage if decent sized stepper.

To answer your question Yes very easily. Just configure the Z++ Limit Input in ports&pins/Input signals to use the same pin number has the home switch.

Be aware.!! . . .Mach will watch the Pin when machines cutting or Jogging around and treat it has a limit switch but when Homing Limits are turned off.
This has nothing to do with your type or configuration of switch it's just how Mach works. This is what makes it's possible to use same switch for both Limits and Homing.
