Re: No Limit/Home switches on Commercial Table....
With programs such as Mach3 etc the limits do double duty, unlike commercial machines where there is generally two sets, one of OT and are hard wired into a E-stop circuit, and one switch that initiates a home routine.
In your case it would depend whether the controller has this feature similar to Mach3, in the very least, you could wire O.T. switches and wire in series with any start relay contactor string.
