Reflecting on Motion Algorithms

I was reflecting on 3D printer motion algorithms and I remembered this short but explicit video by Trinamic. Klipper only uses a trapezoidal algorithm while RepRapFirmware (RRF) and Marlin can do S-Curve. But the new Prunt firmware can be even smoother than all those! Let’s have a look in more details. ...
