eSUN PETG-CF for the A1

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a eSUN PETG-CF spool — the big one first.

Bambu profiles its own filament, not eSUN's. These start from Bambu's PETG-CF reference and apply eSUN's published specs where available.

Why these numbers

eSUN PETG-CF starts from Bambu's PETG-CF reference; eSUN's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
