I have a stringing problem with PLA, I have modified the base profile

Hi everyone
I have a stringing problem that creates this defect, I use the IBOSS pla.

After some suggestions seen on this forum and other suggestions seen online I made these changes to the retraction in this way

And temperature.

but the problem persists, I also changed the filament… what can I change?

stringing

Did you do the following with your filament? (Use Orca Slicer Calibration for the filament and setup the profiles under Bambu STudio Filament Profiles)

  1. Flow calibration
  2. Temp calibration
  3. Pressure advance calibration
  4. Dry the filament properly.

I have found that if I do not do the above with non Bambu Lab filaments I will have some or other issue with the print. Before i use a new filament Make I do the tests and store a profile for the filament. Also making sure the filament is dry prior to printing. Where I live humidity is very high and the filament likes sucking the moisture out of the air.
