eSUN PLA-LW for the P2S

with a 0.4 mm nozzle

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

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

P2S values are provisional
These envelope/flow values still need verifying against Bambu's shipped profile (SPEC.md §10).

Why these numbers

eSUN PLA-LW starts from Bambu's PLA Basic 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.
