I'm printing a tube and the surface is getting all these spiraled print errors.

My prusa slicer file with the stl is here: https://drive.google.com/file/d/1ejtldJZrYMR7lc12VTuXMHx3ugXRk7Vz/view?usp=sharing

I appreciate all feedback on what is causing this and how I can resolve it for a smooth finish.

I love that raw clay circle effect - how did you do it?

@dan-rogers I don't know how or why this is happening ... but it's not the look I'm going for and would appreciate some help to make it go away 🤡

Could you share the STL or 3mF file, and some information about how you set this print up?  It does look to be possibly an under-extruding problem - so what filament, what nozzle temps.  How well is your extruder working?  Do you hear clicking sounds?  Are you printing in an enclosure?

Fixed. The issue was idler screw tension was loose (not calibrated correctly).

That would cause under extrusion for sure.
