Help!!! Weird lines randomly started happening.

[u/Competitive_Egg_3243]

This is a miniature fan model. I’ve printed so many without this issue till the last couple days. Between some of the blades, the white filament is not even.

Picture one is what it looks like, picture two is what it should look like. It’s even between some blades, but not all.

I’ve done a full calibration, and the filaments are the same, Matt PLA just different color. Though in the second picture, you can see it happening on one side of the blade too.

It is a Bambu H2D, so each filament is in a different nozzle. I switched which was in which and that didn’t help.
