I've just set up a couple of switches to home my Y axis (the long one) which has two motors where A is slaved to Y in Mach 3.

Could somebody help explain how to setup Mach 3 so the home switches on each side of the gantry work independently so that the gantry is automatically squared when I hit home?

I had a go yesterday and for some reason the slaved axis carried on after it hit the switch and crushed it! Do I need to set them as limit switches too?

Thanks!
