Why these numbers
Creality ABS (generic family) starts from Bambu's ABS reference; Creality's published specs are overlaid where available, and everything else stays at Bambu's calibrated default.
Reference-table 250 ±5 / 100 ±5; cooling fan OFF; enclosure recommended
Treat these as a starting point — run a flow-test cube and Bambu's Flow Dynamics calibration after import for the last few percent.
