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.

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.
If you want to do a deep dive into adjusting/calibrating the Ender I did write up a bit here (although that post does relate to Klipper and I mention settings/adjustments for Klipper it starts purely with the physical printer itself and builds on it)
Ah, thank you for the advice and the link!
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 figured there might be something like this that i hadn’t seen. I’ll look into it tomorrow, i get the feeling this would cause the inconsistency.
Not sure how it works with your printer, but with mine on Klipper, after bed leveling I have to save and restart the firmware, and then I have to go back and select the profile that I just saved, otherwise it doesn’t use it.
That ain’t right 😹
Maybe try contacting klipper people https://github.com/Klipper3d/klipper/blob/master/docs/Contact.md
Or file an issue if you think it’s a bug.
If you haven’t tuned stuff yet, I’d start here. It’s a great guide to tuning a lot of things
Wow, this is an incredible guide thanks for showing me
If those 2 are from the same job its either a sagging gantry on an ender or the bed/mesh is not tilted properly or not meshed/leveled properly. Check squareness and sagging gantry, then check mesh/level after.
How old is your Bowden tube? Could you be getting more friction when it is bent certain ways leading to inconsistent feeding?
What kind of bed do you have? If your bed isn’t flat this can happen as well. I scrapped a magnetic PEI sheet because it was never gonna be flat enough for a whole smooth first layer for me
Others have mentioned, but looks like 1st z is too low and it’s squishing the lines together on that top right widget.
If there’s a corner of the bed that’s a little higher that could be doing it. The touch is supposed to ameliorate leveling, but I would check the mesh and see if it is crazy bad
Stop buying enders.
Almost every issue in this board is an ender.
I have never bought an ender. I just happen to have one :P
