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 feel you… Been there… Too many times until the hobby was just a frustration and not a hobby anymore.
Are you sure you can’t fix the z offset? My old printer was as bad, I had to manually level it (because the auto sucked )every time and I need to do it a bit closer than the auto level wanted it to and the instructions said. It was so close the first layer was extremely flattened, and I had to try many times to level it. First did I only need to do the bed leveling perfectly (a bit too close) then after I switched to glass did I have to play with the sensor (screwing it a bit further away than their instructions). I did both calibration for like 15 min to an hour… But when I had got it right did it print beautifully! I think if I let it on until next time then I wouldn’t need to do the calibration, but it was loud so I had to turn it off. Btw i think mine was just weird that it calibrated it self only when I started, as in how high up it should be for the first layer so I could just screw up the bed to get it closer.
But now have I switched to bambu lab (enclosed) and it is so easy that it is scary, now I actually trust it and can do big prints that will take more than 3h. I only hit print and it works right away it felt so weird the first 10 prints. I felt empty, my job had been taken away by a robot. Should it be this easy? Why can I use the default values in the slicer? What do you mean I can have it on its default speed and not needing to do it super slow in the beginning? Crazy stuff. It feels like an adult and my other printer was a chaotic 6 years old, they can if they try but they didnt try most of the time…
Also have you tried placing your creation in any other z axes rotation or moved it a bit from the center? I had one print that worked ape shit every time in one direction, switched it a bit and rotated it and then it worked right away. But yours seem to have worked well until it start lifting off from the bed so I think playing with the z offset is the way to go. Be careful tho I switched to glass because it was hard to get it off afterwards, with glass did it pop off right way when the bed wasn’t heating up anymore.
Other stuff: I had heat on at 60 at all time and it was pretty hot in there because of the printer (the room is normal room temperature otherwise), maybe your room is too cold for it, could you build an enclosures? Or is the table it is on shaking a lot? Glue and tape and whatnot never worked for me.
