Sumtor Control Board - homing/limit switches

[JAZZCNC]

However, I am due to my lack of experience, still unclear as to where to make the physical connection/s from the micro switches to the BOB (shown in my attached photo above), I am worried about this part more than anything as I don't want to fry anything by making the wrong connections.

Hi Roy,

I don't know this board at all but It's simple enough if just using Micro switches and just like you thought, take wire from 0v thru the switch back to the Input you want to use.

I've attached a quick diagram showing the wiring for both.

Then In Mach3 -- Config -- ports n pins -- Input signals set each axis limit to same pin number ie:
X ++ = 3
X - - = 3
Y ++ = 3
Y - - = 3
Do the same for HOME Pins ie:
X Home = 4
Y Home = 4
Z Home = 4

Hope this helps.
