Bambu Lab A1 Series

Bambu Lab A1
Bambu Lab Tough PLA and Basic PLA

Tried:
Nozzle temperature 190-255c
Dried filament overnight on bed at ~40c
Dried filament overnight in dehydrator at ~50c
Disabled Zhop
Retraction 0.2mm-5mm
Skip AMS and use external spool only
Cold pull on original nozzle
Bought and tried hardened nozzle
Disabled timelapse
Orca flow test 0 was best
Basic PLA instead of Tough PLA
Less cooling fan maybe a bit better but still stringy with no cooling

Did it happen with any other PLAs (other than these two)? You’ve tried everything I would have :smile:

These are two brand new rolls of Bambu Tough PLA and Basic PLA. I have another unopened roll of Tough PLA but hesitant to try it yet.
