I've noticed that when I jog in the Y-Axis it will move in the Z axis first. It happens when moving in both Y directions. I've attached a video below

This is using the AR4 software after calibration.

The first thing I would look at is the belt tension on J3. I suspect J2 is in effect moving first while the belt tension on J3 is being taken up. This video shows the expected forced deflection on J3. https://youtube.com/shorts/lf_KFFiCdJA I apologize I didnt get a chance to respond to emails yet today - I saw your message and will reply to it also.
