I compiled a custom Marlin firmware enabling the new LIN_ADVANCE feature for my BigBox Pro Hybrid. This results in significant quality increases when printing at high speeds. I printed two 25mm test cubes at 70mm/s, one with the feature disabled and the other with a 'K value' of 50 which seems to work well with the titan extruder. You can see the left print as filament bulges every time there is a direction change while the right uses an algorithm to better control filament pressure, anticipating speed changes. The part is more dimensionally accurate without the bulges.

If you want try this yourself with a custom firmware build, be sure to also set the communication speed down to 115kbps to give room for the extra processing overhead required by the feature.
