I'm a bit confused about how to home an axis to a mechanical switch (and then have Mach reset the DRO to zero when it gets there). I installed an active low switch and configured it properly in the inputs to Home X. I tried the following G-codes;
G28 X0
G28.1 X0
G30 X0
My expectation was that the X-axis would travel to the switch, then stop when the switch activated, and finally reset the DRO to zero. However, it just keeps stepping right past the switch. I'm *positive* its connected properly from an electrical standpoint (I watched pin 12 go low on a scope). Any help appreciated ....
