Uneven layers- Ender 3 I got my ender 3 about a month ago, it was working fine. Tried a new brand, overture, this is when I started experiencing problems. First, I was clogging nozzles left and right, then I went back to hatchbox, and my layers are messed up...
I wonder if this problem is unrelated to your material or printer, and purely a matter of slicer breakage. Have you tried printing gcode files you created before the problem appeared? If you use Cura and upgraded it, you might have hit one of the bugs where it assumes by default you have 2.85 mm filament, even though your printer actually uses 1.75 mm. That will create underextrusion that has the whole printed object coming apart like an unravelling mummy. When I've seen it happen, it looks very similar to your picture.
