I have tried prusament and this: https://www.solunoid.dk/filament/pla...kg-spool-black

I had no problems with adhesion. Maybe your nozzle is too close to bed? Are you using the coated or the smooth sheet? Use smooth for PLA for better adhesion. Use coated for PETG to get the model off the bed.

Fillamentum also works well: https://www.solunoid.dk/filament/pla...s-voodoo-175mm
