Why are my layers messy and curling off the print bed?

I just recently got my first 3D printer (Ender 3 v2) and am also using the Eryone PLA filament. After the first week, I was having bed adhesion problems as well. I think part of the problem is the bedsprings become loose rather quickly.

Here is my current solution, leveling the bed with a receipt paper (thinner than regular 20lb bond paper) and using blue painter's tape on the stock glass bed.

Since using this setup, I have not had any major issues with my prints. I have ordered new bedsprings (Ogrimmar Yellow Springs) and hope these will be a more lasting solution to the loose bedsprings.

Bad filament is my answer. I bought PRLine and both print terrible like your picture. Suspect 2 factors, one is that the line is less than 1.75, so they underextrude and so you see those lines and in some cases gaps, second is the material itself is slippery suggesting to me that it has florinated additives.

I'd add to R..'s answer: It could be:

• temperature is too high - which would cause the melted filament to flow a bit freely

This is clearly overextrusion relative to the volume the material is being deposited into, but that doesn't necessarily mean your extrusion rate is wrong. It could be:

• Nozzle smashed down into the bed (bed way too high) but somehow still extruding
• Problem in Z axis movement preventing the head from moving up the right amount for each layer (possibly not moving up at all?)
• Extrusion (flow) increased significantly above 100% in slicer
• Wrong extruder steps/mm setting (usually controlled on printer not slicer, though you can send a setting in the start gcode)
• Misconfigued filament diameter (unlikely since there's no common setting smaller than 1.75 mm; larger setting would under-extrude)
