So I’m trying to get my printer to a point where i can pretty consistently turn out high quality prints, but I’m at a point now where i get results like this. These two prints are from the same batch, same print job, and I’m completely clueless on how to fix it. I have an ender 3 v2 with a bltouch, I’ve adjusted the eccentric nuts, tightened the belts until the tips of my thumb and index finger couldn’t tighten them any further, bed is level, using hatchbox pla. I know i can do ironing to fix the cosmetic problem, but I’d prefer to fix the root issue if possible.
This is going to sound stupid, but don’t forget to activate bed levelling after performing the leveling measurements. Maybe this is a stupid idea but I put M29 L1 and M29 A at the start of my gcode to load the ubl slot 1 mesh and activate it. Before getting ubl I used M420 S.
I spent way too much time frustrated by bad prints before I learned that leveling wasn’t active.

I thought I’d add that it looks like it’s overextruded. So much that the filament is being “pushed” out and curling back around the nozzle.
It could be the e steps, flow rate, etc but it could also be that your Z offset needs to be adjusted back away a smidge.
That could be part of the inconsistent print since the tool head movement over one section of the bed vs another may be affected by the layer below based on how the filament curled there.

Ah, thank you for the advice and the link!
