<p>I used to have the exact same issue with my Ender 3. I fixed it by applying some glue to the plate before it started printing; the glue makes the filament stick and not drag behind the toolhead without adhering. Additionally, you might want to try manually leveling the bed instead of using the ABL feature. It can be a bit of a pain, but sometimes the algorithm just doesn't work.
As for the glue, I find you can just use Elmer's Glue Sticks, you usually don't need to buy the special 3D printer glue.</p>

Looks like you need to level your bed. Did you do that?

Depends on your printer, some need it before each print, others once per year or just once.

alright i'll try leveling before starting the print with default settings later

update: I tried the leveling feature on my printer, it didn't do anything different, but I did try changing the z-offset from -2.21 to -2.50 and that worked a treat

Good to hear! Question: When you say "tried the leveling feature" did you only run an auto bed leveling (for all I know you might have this set up to occur before every print) or did you physically adjust the height of the bed?

I only ran the auto bed leveling which is not set to run before every print, I didn't see any change with the print quality after that, so I checked some bed leveling infographics and decided that the z-offset needs to be lower/closer to bed based on how loosely the filaments adhere to each other

You have to manually level the bed first, to get an approximate location. Then you use the automatic bed leveling (ABL) to fine-tune the settings. You've apparently not done the manual leveling first. You should not be adjusting the z-axis settings to deal with this sort of issue - you should be doing things properly so that you're not fighting against the printer all the time. There are limitations to what ABL can do. There are great videos available on YouTube that teach you how to manually level the print bed.

# Ender 3 V2 Neo with PLA warping and not sticking on one area

(Asked by: username_0 on 2024-10-28)

## Relevel your bed!

The pattern of your extrusion being laid out on the bed is very typical for the bed being too low. The first extrusion layer should form a flat, solid plate, not distinct lines next to one another.

## Build surfaces are a consumable

The build surface looks very *smooth* and shiny in some areas, indicating it might be worn out to the point that it offers less *grip* than when new. This exasperates any adhesion problem from bad bed leveling.
