Description

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

M200 [D<diameter>] [T<index>]

Parameters

[D<diameter>]

Filament diameter

[T<index>]

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

Examples

A common diameter close to 3mm:
