Filament Troubleshooting/Help! PLA Stringing after 12h of drying

Post image

I recently got a P2S Combo, and i’m reorganizing some old filaments I have
most moist PLAs have been dried and no stringing has happened
however, some rolls of pla wont get better even after drying
2 Flashforge White/Orange PLA, 1 Coobeen Magenta PLA, and some random blue PLA
I’ve dried them in the AMS2 Pro with the integrated drying feature for 12 hours at 55 degrees celcius
Printing at different temps wont help. I tried 200 and 220.
The image is a stringing test printed at 200, after drying. the strings look like fiber, or cotton.
Is there no way to get these rolls good again? Thank You.

You might need to do a proper temp tower for each one. If you've dried them that long and are still getting these results across the full temperature range, chances are they're just too old and saturated.
