There is ONLY a homing switch. No limit.
Polarity is correct. I didn't have an [Axis3] section at all in my ini, since nothing seemed to use it, all references for axis3 functions go back to axis0. I did copy Axis0 section into an Axis3 though, so search-vel does exist now for axis3. Didn't help. I did see this: when it homes, if X1 is ahead of X2, it stops both on X1. However if X2 is ahead of X1, it ignores BOTH homing switches. It just drives both into the stops and grinds forever. The sensors are far enough from the stops now that there's room to go far enough to pass the switches which does create an awkward case where it may start already past it and grind on the endstop without ever seeing the sensor.
