I now get your latching circuit now. Nice one.

I think you didn't quite understand what i was on about with the limits.

I DO want limit switches on all axis. It's easy to 'over jog' if your not careful.
I DON'T use soft limits. Well haven't up to now anyway.

I want 3 of my switches to double up as homing switches. Which i know how to setup in Mach3.

Just been looking at the KK01 breakout board wiring diagram (below) from CNC4YOU and it says you can use 24v with it for the limit switches as long as you add some 1.8K resistors.
Looks like i would have to add one in the Estop signal wire as well.

I think that would mean that I can do away with that second relay. I have modified your wiring diagram with what I think I can do.
See below. Make sense ?



I have made some more space in my enclosure. The 48V PSU now mounts on the outside of the enclosure back panel. I have made up a box with appropriate venting to enclose it. I even painted it the same colour. This will make a big difference to the space I have to play with inside.
I decided it was "Out of the box thinking". LOL

One other thing - been reading about relays and from what I can gather a 4PDT relay can be NC or NO depending on which terminals you wire to. Is that right ?

What u drinking - Guinness?

Thanks Jazz
