If you have systematic shifts on your prints, it probably means that the belt tension is too high.
In fact, a belt that is too tight, especially on the Y axis, will definitely cause this kind of phenomenon.
You must have a relatively soft tension on the belts. When you press the belt up and down after tightening it, you should feel a slight resistance. If the belt teeth are touching, the tension is not sufficient. If the belt does not move because there is too much resistance, the tension is too great.
If shifts occur regularly, loosen the belt a little on the axis in question (half a turn of the adjustment screw is enough to start). Repeat the operation 1 or 2 times if the phenomenon persists.
This may also be due to the geometry itself causing collisions.
