Could be Bearings, Rods, Belts. Something is making the Extruder and Bed go in different directions.

The layer lines or the ringing?

I got issues with the print quality as well. Very awful at the moment.

I've tried different profiles for PLA and same results with IS.

Is there a way to improve it?
