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?
Those lines dont look flat enough to me. https://ellis3dp.com/Print-Tuning-Guide/articles/first_layer_squish.html
The guide is largely klipper oriented but has marlin instructions after the klipper instructions.
Other than that I've tried some samples of bed adhesion aid of different brands which help for printing some of the bullshit filaments that stick to literally nothing and they are much less messy than hairspray or glue and most didn't smell awful, but I haven't found them to actually be necessary for anything other than the really slippery filaments.
