I’ve got an esun dryer box, it seems to be working ok (it gets hot, fan works, it stays on for several hours) but I don’t seem to be able to get it to actually successfully dry my filament.

I’ve got a roll of PETG that’s been out for a while, had problems when printing (popping, lots of stringing, and it keeps crashing when bridging), I figured it’s just wet, but even after 8 hours of drying it’s no better.

So I just need to dry it for longer? Am I doing something wrong?
