I wired all my switches  nc. Only 2 switches to 1 pin. Try wiring both the ys to 1 pin and try it. Mach3 fill automaticly find the y - and call it a home switch. Do the same with the x on it's own pin. It should work fine. Let me know. You will have to reentered the correct pin for the axis.

Thanks for the quick reply! My problem with changing the wiring is that I spent more than a day running the wires neatly with sleeving etc. and would prefer not to rip it all out unless I really have to. I guess I was too confident of success having taken advice from sites and forums that my setup would work. Half of it - the home and -- limits does work (!) so I'm hoping to get some guidance on either the inputs screen or maybe from someone who knows the Uniport BoB.

Cheers, Andy

Mine isn't a uniport but I would think they are fairy similar. Normally nc works the best navigation less trouble. But what I would try is just use 2 short 18 gauge wires about a foot long each and discon net your wire at the bob and connect them up to try it. You should be able to just chang 1 wire on your limit switch to change it from no to nc without having to rewire the whole system.
