K-factor Calibration Pattern

Caution!
K-values for Linear Advance 1.0 and 1.five are not uniform.
Linear Accelerate one.0 is used in Marlin 1.i.8 and earlier.
Linear Advance one.5 is used in Marlin 1.1.9 and afterward.

Utilize this form to generate G-code that you can utilize to calibrate your Linear Advance Grand-gene. Default values apply to standard PLA with a 0.4mm nozzle.

Press the Generate G-code push button followed past Download every bit file to save the result.

Printer Info
Printer Proper noun
Filament
Filament Bore		Diameter of the used filament (mm)
Nozzle Diameter		Diameter of the nozzle (mm)
Nozzle Temperature		Nozzle Temperature (°C)
Bed Temperature		Bed Temperature (°C)
Retraction Distance		Retraction distance (mm)
Layer Height		Layer Superlative (mm)
Extruder		Extruder Index (0...)
Fan Speed		Fan Speed (%)
Impress Bed
Bed Shape		Rectangular or round bed. Circular beds will activate Origin Bed Center
Bed Size X		Size (mm) of the bed in X
Bed Size Y		Size (mm) of the bed in Y
Origin Bed Center		Set the origin position (X0 Y0) to bed center instead of front-left corner
Speed
Use mm/s		Employ mm/due south instead of mm/min
Tiresome Printing Speed		Boring printing speed
Fast Printing Speed		Fast printing speed. This should differ noticeably from Slow Speed
Movement Speed		Motion speed
Retract Speed		Retract Speed of the extruder
Unretract Speed		Unretract Speed of the extruder
Acceleration		Gear up printing acceleration (mm/due south^two)
Jerk X		Set the Jerk for the X-axis. -ane to utilize firmware default
Wiggle Y		Prepare the Jerk for the Y-axis. -1 to use firmware default
Jerk Z		Prepare the Jerk for the Z-axis. -1 to utilize firmware default
Jerk East		Set the Jerk for the Extruder. -1 to use firmware default
Pattern
Lin Advance Version		Select version 1.0 for Marlin one.i.8 and earlier. Select i.5 for Marlin 1.1.9 / 2.0 and up
Pattern Blazon		Select standard or alternate pattern
Starting Value for M		Starting value for the One thousand-factor
Catastrophe Value for Grand		Ending value of the K-cistron
K-factor Stepping		Stepping of the M-factor in the examination design. Needs to be an verbal divisor of the K-gene Range (Terminate - Starting time)
Slow Speed Length		Length of the Slow Speed test-line (mm)
Fast Speed Length		Length of the Fast Speed test-line (mm)
Test Line Spacing		Distance between the test lines. This volition bear upon print size
Impress Anchor Frame		Adds a frame around the start and terminate points of the test lines. May improve adhesion
Printing Direction		Rotates the impress in 45° steps
Line Numbering		Prints the K-value besides every second test line
Avant-garde
Nozzle Line Ratio		Ratio betwixt extruded line width and nozzle diameter. Should exist between 1.05 and one.ii
Z-Offset		Offset the Z-axis for manual Layer adjustment
Use Bed Leveling		Level bed or load a saved mesh (i.e. for UBL) before printing. Bed leveling has to exist activated in Configuration.h! Loading a mesh requires UBL to exist activated!
Apply FW Retract		Apply Firmware Retract. Needs to be activated in Marlin
Extrusion Multiplier		Usually 1.0
Prime Nozzle		Prime the nozzle earlier starting the test pattern
Prime number Extrusion Multiplier		The default of 2.5 results in roughly 1mm of filament for 10mm line length
Prime number Press Speed		Speed of the prime motility
Dwell Time		Inserts a interruption of x seconds earlier starting the exam pattern to bleed off any residual nozzle pressure level
Filename	alert warning alarm

Notes on the settings:

• Fast Press Speed and Slow Printing Speed should be significantly unlike or the K-factor issue will barely be visible.
• Apply Bed Leveling requires a probe.
• For round beds the pick Origin Bed Center is automatically activated.
• The overall width (10-direction) of the print depends on the Fast Speed Length and Tiresome Speed Length settings plus 5mm for the priming line. The length (Y-direction) depends on the Grand-cistron Settings and Line Spacing.
• The script checks to make sure the print fits on the bed. Verify it using a host software like Printrun or Repetier Host.
• Start and End Value for the One thousand-gene determines the range that the examination design will comprehend. For example a Get-go Value of l and an Terminate Value of 150 volition exam a range of 100.
• The K-gene Stepping determines how many examination lines are printed for the above range. For example, a Stepping of ten and a range of 100 results in 10 test lines. A stepping of 3 would not work in this example as 100 cannot be exactly divided by 3. The script will throw an fault message if an exact division is not possible. In this case either the range or the stepping needs to exist adjusted.
• The Alternate Pattern has a second line of Fast Printing Speed to exam 0 to Fast Printing Speed and dorsum to 0 weather. Best used with an increased Exam Line Spacing and reduced Chiliad-factor range.
• The proper K-factor depends on the filament, nozzle size, nozzle geometry and press temperature. If any of these values alter, the calibration might need to be repeated.
