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

          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?

            If your printer has a touch sensor, then raising/lowering the entire bed has no effect on the first layer. The Z offset defines the difference between the touch point and the first layer.

            I think most people calibrate the Z offset for 0.2 mm, and then never change the first layer height.
