Bambu Studio knows 3 profile types:
- Filament profiles, which are for filament, as the name implies
- Printer profiles, these are for machines and nozzles
- Process profiles, these are your quality/strength/print settings
Select the profile you want to save in the appropriate selector. Select stock profiles in the others.
Then, in the Bambu Studio menu, select File -> Export -> Export presets.. and pick a folder.
Download the file from this GitHub or another source.
Then, in the Bambu Studio menu, select File -> Import -> Import presets... and pick the file.
Please try to submit all profiles with a test print (preferrably a Benchy) with default settings other than the applied profile.
This file should be submitting alongside your .json profile as a .jpg, so, for example, if you submit PolyLite ASA.json as a profile, you should also submit PolyLite ASA.jpg with your test print.
