After researching the problem I learned that Snapmaker’s calibration instructions SUCK!
You have us set the z axis with your calibration sheet, and it ends up being way too tight to the print bed.
After hours of searching and reading, I raised the z axis so there is BARELY (not enough to cause it to bend when you push it) any drag on the plastic test strip they provide when you pull it. After that I finally got my 6th print attempt to be mostly successful. There was a lot of stringing. It had a solid square base, so it was easy to remove.
So I then made the following changes after reading more:
Lowered nozzle temp to 195
Decreased flow to 95%
Then I printed a glider. And just like before, I have to practically destroy the print sheet trying to remove parts of the print.
I don’t need better adhesion to the bed, yet adhesion within the prints themselves is weak.
Coming from an IT, tinkering and electrical background, I am thus far not impressed.
Why is the provided filament sticking like glue to the print bed?
