I used to be able to print things. Now for the past 6 months or so I've wasted spools upon spools trying to print anything and this always happens. I'm just about ready to sell this machine and give up on the whole thing.
Is there anything glaringly obvious that springs to any of your expert minds?
What, are you me?? I've had exactly that problem on exactly the same printbed with exactly the same color filament. It also only started happening a while ago, it was fine before. Ender 3 v3 SE here.
I done know why but I fixed it by wiping the printbed with some soap and water and switching to prusa slicer from cura. Works pretty well now, so maybe try that.
