OK so today I'm back on the limit switches. Below is the diagram I currently have, is there a way using the relay that I can have seperate inputs from each limit switch or is it not needed?

I'm going to have travelling switches on each axis (apart from the Z where I can probably get away with fixing it and have the trigger points on each end of the Z axis) and wire them back in shielded 3 core cable...

The home switches I'm going to wire individually into the CSMIO IP-M.....
