Printing on an Elegoo Centauri Carbon 2. This started happening recently. Printer is relatively new, and before I was printing with the filament I ordered along the printer. The prints with the errors occur since switching filament to stuff I ordered later, but I also saw it when I switched back.

Looks like something is dragging across the print. Maybe the print bed is no longer level?

Calibrate your printer and make sure your filament is dry. That's a heat or moisture issue. Get the temp specs on your filament and use that for the calibration.

The print bed was levelled before this print. But your comment about dragging got me thinking, I am under the impression that Orcaslicer does something different. It feels like there are a lot more layers than before, even though I don't remember changing settings for layer height. So I just sliced something I printed before, and the number of layers doubled, the print time quadrupled.

So, after the comment by @Chais@sh.itjust.works I checked my slicer settings again, it turns out the nozzle size was somehow changed from 0.4 to 0.2. I'll do a test print with the nozzle size reset.

If the problems persist I'll check that, though I had this problem with multiple new rolls of filament. For now I'm running a test print with better slicer settings.

It was the nozzle setting. No idea how I managed to change that, but here's the result, left with the wrong setting, right is the correct one.

Filament is notoriously wet from the factory. Just because it's new doesn't mean it's dry.
