X/Y axis artifact on flat surfaces

[Hendrick]

Hi!
Just got my Ender 3 V2 and it has worked very good for me but recently I noticed an issue when printing flat surfaces. It looks like the printer moves incorrectly on the X or Y axis. The preview of the gcode looks fine. When I roll X/Y manually I do not feel any bumps on the wheels.

Anyone with similar issues or knows what may be causing it?

hi，@Hendrick . You can try to reduce the temperature of the nozzle by 3 degrees Celsius, increase the temperature of the hot bed by 5 degrees Celsius, and then print. The wrinkles may be caused by the large temperature difference that leads to the heat expansion and cold contraction of the material.
