Yeah, I know, but I was in a dryer for over 48 hours at 50C , and multiple times afterwards when I was drying other spools and it never got better.

I think it’s just so old and damaged that that is just how it is now. It’s from the previous owner of my printer and just sat out in the open for 7 or 8 years

Funnily I have a similar PLA (maybe 8 years old), it’s very brittle, but if I can get it loaded it print’s fine, though a bit stringy.

I doubt it’s moisture though, I had in a filament dryer for 2 days and it still behaved the same.

I use the same, but I think to be super conservative It should be 1.5x + VRAM

I think I had the option for btrfs on Proxmox (but I did choose ZFS for simple replication to my NAS)
