M200 - Set Filament Diameter

motion Set the diameter for volumetric extrusion.

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>] [L<volume>] [S<flag>] [T<index>]

Parameters

`[D<diameter>]`	Filament diameter
`[L<volume>]`	Set volumetric extruder limit (in mm³/sec). `L0` disables the limit. (Requires `VOLUMETRIC_EXTRUDER_LIMIT`.)
`[S<flag>]`	0 to disable volumetric extrusion mode, otherwise volumetric is enabled.
`[T<index>]`	Extruder index. If omitted, the currently active extruder will be used.

Examples

A common diameter close to 3mm:

M200 D2.85

1.75mm diameter with volumetric extrusion mode enabled

M200 S1 D1.75

1.75mm diameter with volumetric extrusion mode disabled

M200 S0 D1.75

Turn off volumetric extrusion
