Surface of walls showing wavy lines

[MysticalQ]

Hey there,

I was printing a cylinder object and noticed some weird things on it’s walls. Wavy and even some pits.
I tried drying the filament but it still shows the same issue.

The wall itself is 2mm thick, I have 5 wall loops (haven’t played with that) with a 0,4mm nozzle. If I do the math now it should be less then 5? Or does the slicer account do it? I have other parts in the model that are thicker and need the wall loops for strength.
I use pla.

Does anyone know what the issue could be?

You have to calibrate your filaments. If your flow is not right, the walls and surfaces will be unattractive because either too much or too little is extruded.

Thanks for replying. It wasn’t that, it was the model. I adjusted the model and now it prints flawlessly!
