I am not sure exactly how to wire my optical home switches to my cnc4pc c10 bob. I got the reprap opto switches from eBay. They have 3 wires 5v, signal and ground. I have all of my limit mechanical switches wired to 1 port so my home switches could be wired separately.

The inputs on the c10 have 5v and the input number.

I didnt know if I needed to wire the signal to the c10 input, 5v to 5v on the board, and gnd to common board ground.

I dont know?

Thanks Jason
