Hi, So I just got the stepper kit in and hooked it up to my teensy. Im running a test script and no motion on the motor. I then took a shot in the dark and hooked up the driver to a normal old arduino uno and walla motion. Am I missing something?? How are you getting the teensy to drive the motors with just 3v logic?

The Stepperonline drivers (DM542T and the 320) do operate at 3.3v they are supposed to be updating the manual to show that. I assume you are running DM542T drivers. Are you running the AR4 teensy sketch on the teensy 4.1?
