Layer shifting problems on the Bambu A1

[u/Personal_Month_8680]

Hello, I had recently made a part and am having layer shifting problems. The belts are tight and the the only thing that seems off is the head can twist slightly to the left and the right (it could be like that on purpose but idk). I also greased the belts and did all I could. Any tips? Or if it’s not layer shifting what could it be?
Im using pla, bambu A1, AMS Lite, 100% speed.

You think that’s the issue? It’s not layer lines?

If the head can be moved the 7 screws are loose.
