Creality K1 Max Curves Surface Issue - eviltoast

I have a K1 Max and mostly it is running great, however I get strange artifacts on mostly only the front side of curved objects.

I have lubed all the rods, and I have a Capricorn PTFE tube from the filament sensor to the hot end. I tried the printable guide for the tube to go into the hot end but it wasn’t any better and I thought that was the culprit at first.

I have an extension piece to raise up the top glass.

I’m using Elegoo Rapid PTEG running at 240c and 250mm outerwall speed. This is mainly happening on the front side and anywhere on the build plate. Filament is dry and fed out of the Creality Space dryer.

These items are small netcups but it was also happening on the larger sections that they go in.

Using Orcaslicer and Arachne wall generator.

Any ideas where I need to be focusing my attention on?

    to clarify, other parts that aren’t related to the model, do they print fine? or is it just these pairs of models?

    it could be the mesh you’re dealing with is corrupted.

      Good point, I have mainly been printing these items for the hydroponic tower. I do have other versions that I can check. I think after this set prints I will add some basic shapes in different orientations to see if there is issues still.

      That being said I did print some other items that were stacked and each one is much thinner but there are no artifacts on the outer walls.

        Could try rotating the model 90°. If the issues remain in the same location, you’ll know it’s a printer issue, maybe due to the size of the radius.

          So I sliced and printed a different model, and then rotated 1 by 180°, it is somewhat weird as the lowest part on the right model seems ok but as the wall built up on the inside it was getting the artifacts. The model on the left was getting the artifacts on the outer piece but not the inner.

          In rotating the models after, the artifacts are on the opposite side.

          I noticed it was starting at the seam, I have the scarf joint on contour, and noticed that “scarf around entire wall” was checked so trying reprinting to see if that is the issue.
