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.
I had similar issues tho on a custom designed printer. The issue ultimately was the adhesive for the silicone heater for the bed was failing ans slowly delaminating from the bed. When I felt the heater it was plenty warm… But when I felt the center of the bed where it prints it was a lot cooler. I had to replace the whole heat pad. I don’t know what yours uses to heat the bed but my guess would be that it is also on the way out.
