I’ve had the poor wind problem several times on Bambu PLA refills. I think they could up the quality of their wind to the level of other manufacturers.
I had spool of Bambu PLA come apart not long after loading it into my AMS. By the time I got to it the filament had expanded out of the wind enough that I couldn’t lock the spool together again and ended up having to manually wind to onto a new spool. Since then Ive been checking evey Bambu spool for lock and been using the locking shims.
Bambu filament is generally great but they do need to up a few quality control issues.
