Yeah, I mean it's kinda what I'm trying to do now, but I'd like to get it to work native to how I think it should in my mind.
Here's what the page says: When using encoder index homing, the home switch offset is calculated from the encoder reference position, after the home switch has been tripped. To me, it sounds like it should hit the switch, back up until it finds the "encoder index" pulse and zero right there. Why it moves and zeroes at its original power up location is messing with my head. Phil T.
