Linear Advance - ThomasToka/MarlinFirmware GitHub Wiki

Linear Advance is activated in the firmware with a K value of 0.035.

The range is very small so you need to configure the pattern with 0.01 offset.

You can do your own tests and optimize it by using the gcode from the offical pattern generator:
