i have a problem with mach 3 referencing to home. using input pin 11 for x, pin 12 y,pin 13 z. when referencing ,mach 3 hits the limit and the estop trips, does not back off the switch. i hve to switch off motor power and hand crank off the switch. limit overide does not work. the estop wont reset.

tried this setup with mach 2 and works no problem.

Do you have the limit set up and not the Home input ?

Thanks

solved it. i set the debounce to 500 and now works . thanks Brian.
