We don;t have a diagram, but wiring the switches should be pretty straightforward. If all you want are homing switches (no limits) then you need 3 switches:
– X minimum travel – on the left-hand side of the machine by convention
– Y minimum travel – at the front of the machine by convention
– Z maximum travel – at the top of Z travel by convention
Then just wire the 2 wires to ground and Xmin, ground and Ymin, and ground and Zmax, respectively. It’s better to use the normally closed settings (NC). Set the $ST setting accordingly.
I’d start there and get it working, then try the limits if you want them.
Be advised, switches and switch wiring can pick up noise and fire erratically – particularly if you have a noisy spindle. Best to use twisted pair shielded wire, and attach the shield to ground at the tinyg side.
