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've never had great success with glass. I know it's popular.
What's z your offset Calibration method? Have you run that lately? Mine is to print a 20x20 mm, filled-in square and see how good the lines fuse. There are many guides. Look for one that shows the pictures, like this https://www.anycubic.com/blogs/3d-printing-guides/how-to-fine-tune-z-offset
I'm ashamed to say, I do z offset by just tramming with a feeler gauge to adjust. I believe my initial layer is .2mm and I trammed it to.05mm and it smooshed too much, and still peeled up. .07mm was much to tall, and this was at .06mm. I finally got the print working after doing some more cold pulls and recleaning the glass a little better.
