Homing Z will reset the Z=0 position. If the head is not at the same XY position as one of the probe points when you home Z, this may give you a slightly different Z=0 level compared to running bed probing after homing.
Thanks. I didn't think they'd be needed. Just wanted to be sure. Wiring the Y axis in series seems to have worked. Finally printing reliably. Now to dial things in.
