My other Answers, because I wanted to and because I could are just as valid :-D Personally, I am also finding that Linear Advance is giving better prints and usually better print speeds. I can also enable and disable spread cycle, giving access to linear advance, with the ability to revert if I don't like the feature. I have done this mod on my 4.2.2 board, you might ask why? My answer would be, to give better access to all of the features on the TMC2208 drivers, now I don't need to dismantle the printer and probe with a multimeter to access Vref. All of the information you need is in the pdf file, along with pictures and reference material. The mod itself requires some fine pitch soldering and firmware editing of the pins and configuration files. What my mod does is make it a little bit easier to do just the Linear Advance mod or if you want to, you can mod all of motor drivers and give them all TMC Uart access.
It's a fairly simple mod and it follows the good work done by Wong sy Ming on their original Linear Advance mod. I've been working on a little modification and it's time to share.
