Thanks Jimpinder...for your reply, I will wire my home switches in this way as you say. just to confirm,
Ground from 18to25 to Z switch jump to Y switch , jump to X switch, then +5v back to pin 12 or any Input pin, correct?
The reason for wiring switches normally closed , I read it on one of the threads, an it sounded like the safest ! At this point I haven't wired them yet so I can go eather way?
I am only doing XYZ Home, should I enable X++ X-- and so on?
I will use printer cable wire for the home switches, just wandering if you can use solid copper wire very small, or would it brake with the movement?
At this point I haven't used any of my inputs, just picked 12 at random . I need to hook up my charge pump , e-stop , and the spindle inputs, will need the rest for these? Thanks again for yory HELP.
