* 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.

* 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.
