M200 - Volumetric Extrusion Diameter

motion Set the diameter for volumetric extrusion

Description

Set the filament’s current diameter and enable volumetric extrusion. Send M200 with no parameters to get the current settings.

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
