I often see that people have problems with bed adhesion, but mostly it’s because the first layer is not sticking to the bed. I have the opposite problem – the first layer is practically glued to the bed. This is my scenario:
- I have the A-350 with the Snapmaker enclosure and I’m using Hatchbox PLA filament.
- I replaced the “sticker” with a brand new sticker. I had the same bed adhesion issue with the sticker that came with the machine and I was using Snapmaker filament. Someone in this forum suggested that an overly adhered print may be due to a “bad batch” of filament that was sent out with the machine. I no longer think this is the case because the same issue is occurring with the Hatchbox PLA.
- I’ve leveled the bed using the maximum amount of auto-level points. I used the calibration card that came with the product, ensuring that the card has tension when pulled out, but not so much that it’s impossible to move.
- I’m using the default “Fast Print” setting in Luban. This setting uses 205 C printing temp, heated bed temp 50 C, and initial layer temp of 70 C.
This is a photo of the underside of my print. The area in the upper right quadrant was adhered to the bed as if it was Super Glued:
To remove the print, I used a combination of the palette knife and brute force – obviously this is not good for the print nor is it good for my brand new bed sticker. After I removed the print, I scraped the skirt off of the bed using the palette knife, razor blade and alcohol:
Basically, my brand new sticker now looks like my old sticker. Before I flip it over and destroy the other side, I’d like some feedback as to what I can do to avoid this issue with future prints.
