You can see where around corners and even some straight runs it is peeling up. I’m running first layer at an agonizing 15 mm/s. Using hatchbox pla filament, just dried in dehydrator. 200° nozzle and 70° bed. The glass is freshly cleaned with soap and water, I just did several atomic pulls, I’ve trammed at different heights using a feeler gauge, and absolutely nothing is working. Any one have any ideas?
Hey man, your first layer isn’t getting enough squish by the looks of it. It likes a decent amount of push into the bed compared to some other materials. PETG doesn’t like as mush mash down as PLA. So if your printing PLA, try increasing your squish. You can do this via your z offset.
But do you really need your bed at 70? Mine runs and sticks just great at 60. 70 seems a bit warm for pla, as it keeps it just a bit too close to the glass transition temp for my liking. But if 70 has worked for you, then stay there.
But as another suggested, maybe raise your first layer temp by 5 or 10 and see if that helps. It might be that it needs a bit higher temp to flow better.
Increasing temp by 5, plus recleaning the bed, plus doing some cold pulls helped a bit. I’ve always had issues getting things to stick at 60 for some reason, at least ever since I went to borosilicate. I’ll try adding more squish, since I have to dehydrate my filament before I give the print another shot.
