Bear with me, I'am thinking outside the box here!
I am using a uc100 usb to my control box. Why can't I use the parallel port to wire the zero probe and safety switches. If I cut the end of an old parallel cable and only use the post that would normally be used for probe and switches. All the wiring diagrams that I have seen show pins in the parallel port.
I realize you can't use both the parallel and uc100 because Mach3 won't let you, but if I am only using pins that are extra anyways, could it be done.
Has anyone ever tried this?
