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?
Looks to me like your offset is wrong, or your first layer height is too large
Yeah, agreed. It looks like it could use a bit more squish.
Seconded (or thirded?) I have a (textured) glass bed and my first layer is usually quite a bit more squished than this
I was able to get it printing, but doing some calibration confirms that adjusting z offset made the bottom layer better. What's the point in z offset specifically, vs just changing the gap when tramming or the initial layer height?
