Hi,  
It’s called banding. It’s very tricky to solve this problem.  
Generally, you have to adjust the nuts on each Z-axis, but it’s very complicated to repair completely.

Are you talking about the diagonal at the top?  
I hadn’t seen it.  
If so, I don’t know.  
Have you checked the model?

I understand.  
You’re right, it’s the seam.  
You can choose the position of this seam in the settings of you slicer

I’ve had similar artifacts created by having scarf joints turned on and not having the settings quite right.
