Do not use mechanical switches for HOME / ZERO switches. Use instead optical interrupters, they are much more repeatable and have less hysteresis than mechanical switches.

Thanks Michael, great idea because I was playing with limit switches and they didn't look good. I have to add a little plate to each axis to go in the slot of the optical interrupters.
