Thanks, I have repeatedly reviewed this section of the Mach 3 manual. It calls for NC limit switches. I have NO proximity switches installed per the manufacturer. So I am trying to determine whether this will work with homing and limits? I was able to trace all 3 wires from the proximity switches (12V+, 12V-, and share from the switch and 12v+) I was trying to determine whether when one of these proximity switches is closed, is it sending too much voltage to my Chinese BOB? Its seems they are not going to 0V when the proximity switch is activated?
Thanks,
