eSUN PETG-Matte for the A1

with a 0.4 mm nozzle

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

Why these numbers

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