Unexpected motion in X when moving Y
When homing Y I noticed T1 jumps (See video). I went back through the commissioning guidfe and noticed VERY small movements in the toolheads during the Y-Axis Direction test.
I inverted the directions pins for Y, which made things worse.
I feel like this could be related to tension, but unsure.
