I found this in a different post, I was just wondering if the grounding at the driver end meant connecting to pin 2/3/4 on the gecko in this 1st page of the diagram - or if it meant connecting to pin 12 as it is in the 2nd page

I am trying to figure out how to setup the home switches. I assume that I would use input 1-3. Any advice would be appreciated
