If your usual printing temperatures differ feel free to modify the G-Code lines to your needs.
Change the "S" values:
M104 S215 ; Set nozzle temperature (no wait)
M140 S60 ; set bed temp
M190 S60 ; wait for bed temp
M109 S215 ; Wait for nozzle temp
If you have custom printing profiles and you want to generate your own LA15 K-factor values visit the community Marlin k-factor generator Prusa Edition and download at least all '*.js' and the 'k-factor.html'. You can open the k-factor.html in your local browser and enter your values. This is based on Marlin k-factor generator with Prusa specific G-codes and settings.
Naming convention for the G-code files:
LA1_5-"Filament"-"Hotend temp"C-"layer height"mm-"fastest perimeter printing speed"-"Extrusion multiplier"E_mult-"Prusa Slicer Printing profile"-"Printer type"-cal-kfactor.gcode
Example:
LA1_5-PLA-215C-0_2mm-60mms-0_95E_mult-SPEED-MK3S-cal-kfactor.gcode
is:
- Linear Advanced 1.5 k factor pattern
- for PLA
- with 215°C hotend temperature
- at 0.20mm layer height
- fastest perimeter speed 60mm/s
- Extrusion multiplier
- Normally it is based on the Filament Extrusion multiplier setting (default 1).
- But there is some custom/modifying g-code in the Prusa Slicer
Original Prusa i3 MK3S
profile that changed it from1
to0.95
- based on Prusa Slicer
0.20mm SPEED@MK3
Printing profile- which has also custom/modifying g-code to set different E stepper motor currents.
- on a MK3S printer.

These G-code files have been generated with a modified version of Marlin K-factor generator.

Before you print this G-code make sure that you have dialed in the Live-Z as optimal as possible.
Too squished layers will make the determination of the LA1.5 k-factor value really hard.
