Printer is Ender 3 V2. .4mm nozzle, PLA. Bed is freshly cleaned.

 

Whenever I print a bigger model, the print doesnt want to stay on the bed. It is perfectly leveled, I make sure before every print. But some lines still detatch themself from the bed / dont stick properly. And its sometimes in a random line. Especially most outer corners dont want to stick (nearest to the bed end).

Hairspray makes things even worse. The textured printing site doesnt work at all.

Tried highering the bed and nozzle temp, but didnt do any better.

Else, there are these weird lines mid-print, that seem to high and not squished, but its in the middle of the print… (2nd pic)

I am very frustrated since I dont have any more ideas how to fix that. Smaller prints in the middle work just fine, just the first layer on big prints is a HUGE problem…

 

Can somebody help?

Thank you!

@caenerys replace your v-rollers, they might have flat/high spots.
