Limit switch problems

[Neeps]

Thank you both. It seems there was a break in one wire to one of the switches. So as suggested I daisy-chained both z axis switches together. I think I had developed brain ache by then though as I had wired them in parallel! Then did it properly and 100% now. Thanks again.

bottom Z axis ? why would you want a limit switch on there ?

ideally you are correct in having NC switches, this is so that if the wire is damaged and breaks the machine will stop
if the wire breaks on a NO switch , the machine is non the wiser and carries on , prolly resulting in a crash :-S

im suprised your machine ran with a break in the wire ... it shouldnt have allowed you to

I think he said he had them wired in parallel
