In this video, I show you my new development which is a high-performance 3-axis stepper motor control board. It is high-performance because it uses the super-fast Teensy 4.0 microcontroller and it also uses a modern TMC429 stepper motor ramp generator controller together with three TMC2209 stepper motor drivers. The board can be controlled via buttons and a joystick, and I also programmed it to be fully controllable by sending commands and parameters via the serial terminal.
