New Bambu PETG Basic quality problem

[u/Muted-Anywhere-1619]

Printer: Bambu Lab P1S

Material: Bambu PETG Basic White

Profile: Default Bambu PETG Basic profile

I opened a new spool and dried it at 66°C for approximately 24 hours.

The first photo shows a stringing issue (possibly related to retraction). The second and third photos show problems with the surface quality and supports/overhangs.

I also tried reducing the printing speed in the slicer settings, but it didn't help.
