I have noticed that Slic3r offers a speed setting called "auto speed" meant to give a constant filament pressure at the extruder, which I believe could eliminate filament grinding issues at higher printing speeds.
According to the tooltip in Slic3r, auto speed is calculated from two parameters:
- Maximum speed
- Maximum volumetric speed
Maximum speed speaks for itself, but how can I calculate the maximum volumetric speed of my print?
