Bambu Lab ABS for the X1

with a 0.4 mm nozzle

The five values to type into Bambu Studio for a Bambu Lab ABS spool — the big one first.

Why these numbers

Bambu Lab ABS starts from Bambu's ABS reference; Bambu Lab's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.

Enclosure required. Speed/density/drying from V3.0 TDS PDF.

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