If you are having adhesion problems or just want to improve adhesion on your PEI print surface this might help.
I will show you a simple mod to get better adhesion without glue, sprays or tape. You can watch how I tested the before and after and see the results.

This is in no way an alternative to having a calibrated machine, level print surface, clean print surface and good first layer. With all of the above plus this mod you will only improve your adhesion.
