Hello, I am relatively new to 3D printing and I am looking for a solution to this. I have an Ender 3 v2 Neo with Klipper and I use Orcaslicer. The problem is that when starting the perimeter it leaves waves, this does not occur in all the layers, but they do repeat the same patterns if you print the piece again. I had underextrusion in mind, but the other layers look good, what do you think?
