About homing and switches...

Couple of odd comments:

IP/M is very happy with direct connection of prox switches running on 24V. Works well.

IP/M drives the usual stepper drivers directly without needing any resistors. Use differential connection if your drivers support this - better noise resistance.

Unlike Jazz, I've not been too lucky with prox switches from eBay. I bought a box of ten. One was the wrong type (unbelievable! Two-wire, quite obviously not the same as the rest of the 3-wire switches), one was faulty straight from the box, and one failed very shortly after fitting. However, the rest have been working fine for a couple of years now, and the whole box probably cost less than one "professional" quality switch. That's the difference between home building and commercial - commercial machine could not stand that level of quality, but it suits my pocket!
