I am working on a new conversion project. Converting a benchtop mill to cnc. I have a cnc4pc c10 breakout board.

i do not see on the c10 board where I can wire in limit switches. I am not an expert in electronics. Can the limit switch be wired directly to parallel port pins?

does anyone have a good diagram of how limit switch should be wired?

Thanks in advance.
