Hi Marimakes,
I have a ULTIMAKER s3, AA nozzle with black ULTIMAKER 3 PLA and BB with PVA.
I have printed a few times with unsuccessful results and mostly the file was irrelevant.
the latest was this one from thingiverse:

I tried to print with one printcore only, which obviously is not allowed, than I removed the pva material and send a file to print. The same ridges appear and they seem to be all related to the BB core scratching on the PLA material of the build, causing imperfections or material drag in the worse case.

Hey @luca_hbmp,
I moved your comment away from the clogged printhead thread to it's own topic.
I'm happy to help troubleshoot your problem.
You seem to have some under extrusion that can be caused by a number of things!
What is the filament you are using? How old is it?
When is the last time you cleaned your feeders and cores?
Can you share the project file with the settings?
