Tells you: How much plastic per second your nozzle can melt with that filament.
Calibration menu › More... › Max flowrate · It works the same on any FDM printer. The menu is Bambu Studio's; Orca Slicer has a very similar one, and in other slicers you print the same test with a downloadable model. Can't see the menu?
How
- Print a piece that goes faster and faster as it rises. By default it starts at 5 mm³/s and adds 0.5 mm³/s for every millimeter of height, up to 20.
- With calipers, measure the height where the wall starts coming out rough, gappy or thinner.
How to read it
Your maximum = 5 + height in mm × 0.5. If it fails at 24 mm: 5 + 24 × 0.5 = 17 mm³/s. Use a value a little below that, to keep a margin.
Calculator: enter what you read on the piece
The measured maximum is 5 + 24 × 0.5 = 17 mm³/s. Write down a little less, to keep a margin.
Where the value goes: Filament › Filament › Volumetric speed limitation › Max volumetric speed. The printer will never ask for more than that, whatever the process speeds say.
