Sorry for my ... uuuhm "creative" title.

Humm. What does happen next?

I see some banding on the layers which has a few causes:

Build quality (belts not tight/over-tight
Pulleys not tight
Inconsistent filament feed (from spool onwards)
Extruder pulley not tight/dirty
Poor quality filament
Partial nozzle/PTFE blockage
Excessive retraction
Z Axis not moving freely (if using Z-lift)
Bad slicing parameters.
Plus others that won't come to mind at present.

Go back to basics and print a model from the SD card; doing that will eliminate a few potential problem sources.

I have seem this just last week. Is that part hollow (only shell)?

I found that printing as solid (infill (no matter whch one)) fixed it. The real cause in my case was that I scaled the modell quite a lot up and down during preparing it in my CAD and so I think there was also a precision problem, causing the slic3r to get confused and having the perimeters flap a bit in the breeze. The slicer tried to reach the exact wall thickness with two perimeters and altered the extrusion etc. which worked not well...

Thank you for the answers! The Issue was a missing nut on the pinda probe. I found the nut 2 weeks ago and didnt think much about it. Until i noticed that it was missing at the bottom of the probe. Prints are nice and smooth again.
