M200 - Set Filament Diameter

planner Set the diameter for volumetric extrusion.

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.


Usage

Argument Description
[D<diameter>]

Filament diameter

[T<index>]

Extruder index. If omitted, the currently active extruder will be used.
