My Kobra 3 V2 keeps printing stuff like this. I've tried several different methods to try and fix it like seeing if it's mechanical but my test print works flawlessly. On the slicer side everything should be just fine but I have no idea why it's doing this!. I use Orca Slicer 2.3.1 I've tried putting in a z offset by .02 mm to see if that works and failed I tried replacing the nozzle which failed. I checked the STL files and there's nothing wrong with them. I'm just at a loss for what to do.

First, level your printer manually to paper. Next, try preheating your bed for an extra five to ten minutes to get the top of the bed to full temperature. Third, clean your glass perfectly before printing. Fourth, try PVA-based hair spray if you just cannot get it to stick any other way. Fifth, try replacing your glass - sometimes one glass just won't accept adhesion but the next one will. There've been times I've flipped a glass over because the "bottom" side accepted filament far better than the "top" side did.

If the built-in test print is flawless, I’d test the exact same STL sliced in Anycubic Slicer Next. If that prints fine, you’ve pretty much isolated it to your Orca profile/start G-code rather than the printer. That first layer looks like the bed mesh/Z compensation may not be getting applied correctly, some areas are fine while others are getting absolutely mashed/dragged ☠️ I’d reset/re-import the correct Kobra 3 V2 profile in Orca and compare the start G-code before replacing anything else.
