[Marlin] M200 - Set Filament Diameter
📅Update: 2020/09/18
Set the filament's current diameter and enable volumetric extrusion.
In volumetric extrusion mode the E axis specifies cubic mm instead of linear mm, and the firmware calculates how much length to extrude for the given volume based on the filament diameter.
