UPDATE: This process has been streamlined with a easy to use gcode generator for the acceleration tower. All explained in this video: https://www.youtube.com/watch?v=rp3r921DBGI

Tuning your 3D printer acceleration is the next step in getting the most of your machine. With this and junction deviation, you can find a nice compromise between speed and surface quality, eliminating ringing. In this video I calculate and tune to match a very high print speed, but this works the same for any feedrate.
Testing the fastest an extruder/hot end combo can push through filament is pretty interesting, and I may repeat this test for future upgrade videos.
