Full brims, mouse ears, with glue, without glue, higher bed temperature, lower bed temperature, flat base, concentric cutout base - whatever I try, I seem to be getting wank adhesion, major warping, and ultimately this shitshow.
Dry PLA, warm room, no draught, plate cleaned with IPA. I’m going to fucking punch this thing in its stupid fucking face.
Edit: Prevailing advice very much seems to be to bust out the Fairy liquid and give it a good scrub, so I’ll try that. It’s a Kobra Neo 2 so is auto-levelling, so I can’t piss around with any of that stuff (as far as I know). Another quick question while I think about it, does everyone always print onto the bed at ~60°C? Because Orca Slicer’s default for a textured PEI plate is 45°C, which seems mad. I think I tried it once and it was shite so turned it back up to 60.
You have already gotten a ton of good suggestions already but I’d like to vouch for the Ellis 3d printing tuning guide and Suave Mega Hold Hairspray (huge pink can).
If you follow it from beginning to end you will have those prints coming out looking clean and actually sticking to the bed. It will take you a few hours but I promise you won’t regret it.
I find in 3d printing, sometimes it actually matters in what order you do your tuning.
Hot tip: Read the instructions first before you start doing anything. I kept making mistakes because I didn’t do that
