* Assumption: advance = k * (delta velocity)
|

* Assumption: advance [steps] = k * (delta velocity [steps/s])
|

* K=0 means advance disabled.

* See Marlin documentation for calibration instructions.
|

*
|
||||
* NOTE: K values for LIN_ADVANCE 1.5 differ from earlier versions!
|

*
|

* Set K around 0.22 for 3mm PLA Direct Drive with ~6.5cm between the drive gear and heatbreak.
|

* Larger K values will be needed for flexible filament and greater distances.
|

* If this algorithm produces a higher speed offset than the extruder can handle (compared to E jerk)
|

* print acceleration will be reduced during the affected moves to keep within the limit.

|
||||
* 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 `M900` to override this value.
|
||||
*
|
||||
* Example: `M900 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
|
||||
*
|
||||
* Example: `M900 R0.0458` to set the ratio directly.
|
||||
*
|
||||
* Set to 0 to auto-detect the ratio based on given Gcode G1 print moves.
|
||||
*
|
||||
* Slic3r (including Průša Control) produces Gcode compatible with the automatic mode.
|
||||
* Cura (as of this writing) may produce Gcode incompatible with the automatic mode.
