Hi
sorry i have lead you down the wrong path here .
I am fitting home switches one on each axis and highlighted as such in mach 3 ports and pins . i have noticed that the function for "auto set of the ports and pins " is not there very strange this may have made things a bit easier .
After allot of homework i wired each switch to the individual pins and all 3 earth wired to the earth point on the board as i am lead to believe that a parallel circuit is for limit switches ,maybe this is right ?.
I have not yet set up soft limits until i home the machine to the switches .
Im sure im doing something completely dumb here but time will tell , so frustrating
thank you for your input
