I'm sure this is on here somewhere, but I can't seem to find it. Might be calling it the wrong thing. I'm using Mach 3 for my Plasma Table I just built and I'm using Master and Slave Y Axis Motors. Lots of people do it so I'm sure it's just some setting somewhere.

How do I home Motor 2 and Motor 4 together, but when one reaches it's own limit switch it's stops and the other motor continues on until it reaches it's own limit switch? That way the system will self align the Y axis from racking.

Thanks.

Just make sure that both the master and slave have home switches assigned, each on different pins, and make sure  "Home Slave with Master" in General Config is NOT checked.

Ok, but will that move both Y motors at the same time then make the trailing one continue until it hits it's own limit switch?

Yes, each will move to it's own switch.

Cool thanks
