+   * Some Slicers produce Gcode with randomly jumping extrusion widths occasionally.
+   * For example within a 0.4mm perimeter it may produce a single segment of 0.05mm width.
+   * While this is harmless for normal printing (the fluid nature of the filament will
+   * close this very, very tiny gap), it throws off the LIN_ADVANCE pressure adaption.
+   *
+   * For this case LIN_ADVANCE_E_D_RATIO can be used to set the extrusion:distance ratio
+   * to a fixed value. Note that using a fixed ratio will lead to wrong nozzle pressures
+   * if the slicer is using variable widths or layer heights within one print!
+   *
+   * This option sets the default E:D ratio at startup. Use `M905` to override this value.
+   *
+   * Example: `M905 W0.4 H0.2 D1.75`, where:
+   *   - W is the extrusion width in mm
+   *   - H is the layer height in mm
+   *   - D is the filament diameter in mm
+   *
+   * Set to 0 to auto-detect the ratio based on given Gcode G1 print moves.
+   *
+   * Slic3r (including Prusa Slic3r) produces Gcode compatible with the automatic mode.
+   * Cura (as of this writing) may produce Gcode incompatible with the automatic mode.
