AERO PLA Retraction problems

Bambu Lab A1 Series Troubleshooting
1

Hi guys!

Have some problem with printing model with Bambulab PLA-AERO
Main problem with retraction how I think, there is always leakage of filament from hot-end.
All settings based on manual from Bambu wiki, filament was dried for 8 hours based on Bambu wiki as well.

When printing retraction test tower it’s totally not helping. Maybe somebody fix that problems

isn’t the whole idea of PLA aero? that is foams/expands to save weight, I would think that stringing is almost inevitable.

But just a quick search found this topic/guide:

Good luck!
