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.

Appears it was related to belt tension
