Add 8 more Inputs for Mach3 Red (RnRMotion)

This board has only 4 inputs and 4 outputs and maybe we want to add some extra buttons like Start , Pause and these 4 inputs just not enough. But It has some hidden inputs , what is I say you can add 8 extra input (just as general inputs purposes)??

Yes , there are extra pins on board and we didn't notice!!

these pins are for MPG (handwheel) but the documentary of the board mentions these feature .

when I was searching about the wiring of MPG (    • Mach3 MPG Wiring and Full Config   ), I just found this feature …

This video is just for introduction and showing the prototype of mine.
you can design box and buttons better then mine.

In the next video I explain everything and not just this board has extra hidden inputs ...
