HOW IT IS CALCULATED
Calculate extrusion volumetric flow
Multiply line width, layer height and print speed.

01Values
02flow = line width × layer height × speed
03Result
0.45 × 0.2 × 60 = 5.4 mm³/s.
Speed alone does not determine hotend demand
A wider line or thicker layer increases required volumetric flow even when print speed is unchanged.

In short
What logic does the calculator use?
flow = line width × layer height × speed
Example?
0.45 × 0.2 × 60 = 5.4 mm³/s.
