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?

Many suggest adding some type of adhesive to the surface, and I have a trick that might interest you. Glue sticks and hairspray are messy and are a pain to clean. When I used a glass bed, I kept about a tablespoon of sugar dissolved in little less than a cup of water nearby. One could use a paper towel to wipe a thin film over your glass bed. I did this as it warmed up and the water dried quickly, leaving a thin tacky surface. One could put it in a small spray bottle too. Very easy to clean with water. If you eventually get buildups after weeks of printing, a quick wash with soapy water cuts through instantly. Give it a try. I could never get PLA to stick to my glass bed. PETG worked sometimes, and other times it bonded too well and broke the glass when it was removed, or cooled to the point of removing. The sugar water worked there too in providing a sacrificial layer that protected the glass and made removal easier.
