I wanted to set X axis home switch's. I use two motors on the X axis "X" and "A".
My breakout board uses pin 12 for X home. When I hit Ref home the X motor homes, back off, and slowly comes back and trips the X home but the A motor keeps going.
OK, so I think, I'll just put a home switch on the "A" side of the X axis and wire it into the breakout board.
OPPS There isn't an empty pin for "A" home switch. This is how the break out board is wired.
Limits Y home X home Z home E-stop
P 10 P 11 P 12 P 13 P 15
So now what do I do?
After spending some bucks on nice roller switches and hours making ramps to trigger them and more hours drilling a tapping I'd really like to make this work...
