Vertical marks on circular parts

[Psevilla 0]

Hi, I'm having this issue where circular prints have 1 or 2 of these vertical lines. These are not seams. The seam is located at the other side of the part. It only happens when I slice with Cura. I have used Orcaslicer and Ideamaker and the lines don't appear, so I'm pretty sure is a Cura problem. Also, this marks are not shown in the Cura preview. How can I solve this problem?

If Cura previews showed marks like this, we wouldn't print things after we saw the Cura previews 🙂

 

It might just be the way the light is hitting it in your photo but it looks like there's a seam in the model along that vertical line - did you model half of it and then mirror it or something? It looks like it's started/stopped printing either side of it the whole way up.

 

Also, could you please provide the Cura project file (.3mf, in Cura go to File > Save Project) so we can have a look at it?
