No change with rotation is weird. Do you mean the artifacts are on the same side relative to the parts, or relative to the printer?

Is this a modified MK3S/S+? I see the extra screen, but what about the PTFE tube, is that from an MMU?

If the inertia is from the relatively fast movements between parts, no. Printing moves are more gentle than movement-only moves.

Edit: It may be worth trying to print at 50% speed (knob anti-clockwise during printing) just to see if that changes anything.

Hi Kylian, Are all these printed in the same orientation? What happens if you print one rotated 90 (and 45) degrees on the vertical axis?

I find it curious how the artifacts are more pronounced on one side than on the other (last image).

The problem occurring with tall prints make me think this could be inertia from the bed slinging. How badly does the printer shake? Do you print using the spool on top of the printer? If so try with the spool to the side. I’m fond of this spool holder https://www.printables.com/model/120198-spool-holder

Feel free to follow up with more questions. Don’t hesitate to reach out to Prusa support either, they’re great.
