The 10 pins are connected to the DB25 pins 10-17 and pin 1, plus a gnd pin. Some of them are pulled up to 5V. The input pins of these would be used for limit's and home switches.

Ok, i think that i got it.

So all the home switches got output from pin 1 like dokuments says (1 O switch)

Wire from there goes to homeswitch and from home switch it goes some of those 10-13, 15. Is that correct?

What are those 4 O NU (pad D2) and 7 O NU (pad D5) ?

I havent tested anything else except X, Y, Z DIR and STEP anad those works just great.

One side of the switch goes to a pad for pin 10 as example the other side of the switch goes to common. The pads are just solder points for unsed DB25 pins.
