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 0.005 offset.

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

Here are example settings for a basic calibration:

linearadvancepattern_settings

linearadvancepattern_printbed_speed

linearadvancepattern_pattern

linearadvancepattern_advanced

The generated pattern is here:
