PEI? If you mean the black stuff shipped with overture filament thats too small for an ender 3, has an adhesive backing, I just pieced 2 of them together to get a glass cover that covered the spots it checks for bed leveling, and let it run on this file for about 15 minutes. I'd attach a pix ,but the camera battery was dead, again. > An occasional wipe with an alcohol-soaked rag helps on the occasions > when adhesion isn't working. Paint store alky I assume, or is 91% good enough? I'll give that a shot, after the battery is charged. It stuck way too good doing a nozzle gap test, took most of an hour to dig the petg back off this stuff with a very sharp putty knife. But start this bearing file, its 48 megs and 6.5 hours to render and its like the matt has been sprayed with a silicone film. Zero adhesion even with the bed at 80C and the 234C nozzle jacked up to 255C. Thats what made the mess I'll show a pix of. I found lookalike nozzles from microswiss and ordered 2, and this matt stuff in a size for this printer and ordered two 3-paks of those. Something's gotta work, but I've not found it, yet.... Thanks Andy. Pix later. > In fact, PETG has been sticking a bit too well recently. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
