Why does filament not stick to the glass? (midwest.social)

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?

I was having trouble with my glass bed originally, to get it working nicely without glue or hairspray I:

made sure the bed was very clean, I use rubbing alcohol to clean it
dialed in my z offset, I usually match it to my layer height, so if I'm printing at 0.2mm that's what I set the z offset to
upped my print temp a bit, I usually print at 205-210 with PLA

Maybe one of those will help?

+1 for upping the temp. I always find printing the first couple layers at 5° hotter to helps a lot with adhesion.

Increase in temp seemed to help!
