Hello, I'm having a problem with home switch setup in mach-3. I have my switches wired in series to one input pin (pin 11). My switches are operating correctly when I test them on the diagnostics page. The yellow light comes on when I press any of the switches. The problem is, when homing the z axis moves slowly up until the switch is triggered, but it doesn't back off the switch. It zeros the z axis dro, but the yellow light on the diagnostics page is still lit, and I get a warning message telling me that "one or more home switches is triggered, fix then home." Any ideas?
