Noise comparison between Toshiba and TMC2209 stepper drivers

Noise comparison between different stepper drivers for my Loklift. The original driver IC that I used was a Toshiba 6564, which was powerful, fast but (like most stepper drivers) quite noisy. Now I'm using a TMC 2209 (TMC 2226), which has less power, and is therefore slower. More important, however, is that noise went back from around 70 dB to "only" 50dB.

Hey Aiko, what a great lift. I would love to get more technical infos about it to build one as well…
