Thanks for responding.

I am OK with connecting them in series or parallel depending on the switch.

The switches I have can be both NC or NO (3 wires connected but I assume only 2 are in use at any one time) and at the moment I don't know whether the 3 I have connected (1 each to the available connectors ) are working as NC or NO, but they are working.

My issue is that the labels on the board mark the limit switch connector pins as X+ve, common and X-ve.


This suggests to me that one pin is for the limit switch at the positive end of travel and the other for the negative end.

Against that I have now got one switch connected for each axis and they all work fine.

Before I start cutting wires and experimenting (and possibly frying the board!) I was asking if anybody had solved the issues.
