It looks like I am one of the few who is having very bad luck with my newPEI sheet. I cannot get PLA or ABS to stick very well. I have tried the following:
Cleaned with IPA
Cleaned with Acetone
Cleaned with Acetone then IPA
Tried hair spray
Tried PVA glue stick
Tried Elmer spray adhesive
lowered and raised Z offset (inductive sensor auto level)
Increased bed temp 50-80 PLA and 70-100 ABS
Increased and decreased extrusion temperatures
I have abraded the surface with 280 grit sand paper
I have to note that i used Kerosene to remove the Elmer spray adhesive. IPA and Acetone would not touch the stuff.
I will admit I have been able to finish some prints with PLA but the corners are pealing up. I just can't believe blue painters tape is so much easier to use that this.
Its a bummer, but I actually put blue painters tape on top and the only adhesion issue was the tap to the bed. Filaments stuck great to tape.
