TMC2208 stepper motor drivers are a popular choice for reducing the stepper motor noise on 3D printers and laser cutters, particularly because they are able to easily replace the A4988 drivers which are commonly used. I wanted to test them out against the A4988 drivers to see how much quieter they actually are. The results were quite surprising!
