New start

Have tried my HOMEs now. Signal is high unless any switch is triggered.
This works but should a wire fail Im in trouble as I'm connecting 3 axis paralell to one input?

The slaved axis with separate input is safe because I would notice a broken wire?

If Just home switches then don't worry about it because if one fails the Limits will catch it.

I'm comforted now... thanks ;)

...as long as you use the NC contacts for the limit switches! Simplifies wiring as well as they can all be in series taken to a single BOB/motion controller input pin. I use proximity switches myself; mine are arranged in pairs (min/max limits on each axis) and wired in "series". Doing that is slightly more complicated than with mechanical switches but it works fine. I tested them with 4 in series (remembering that I also use 24V) and they seemed to work OK as well.
