PETG no longer sticking to powder coated sheet
I am having a problem where Atomic Filament PETG is no longer sticking to the powder coated sheet. It will stick great if I apply adhesive like Layeneer, but it will not stick anymore on the sheet directly. I've tried washing it with 91% IPA and with Costco dish detergent and a plastic brush, but no more. Any suggestions besides trying to coat it every single time with adhesive?

Sorry, I mean that I have adhesion problems even after washing it with IPA or with dish detergent: filament sticks to the nozzle instead of the bed. And yes, I've calibrated the first layer ad nauseam.

If it won't stick - lower your Z until it starts to bead, then watch and carefully lower some more.

Update: Cleaned the bed with a LOT of dish soap. Then Windex. Then water. Then 91% IPA. Then did a recalibration. All better now.
