    Does anyone know the UC300 "Digital Dream" controller card by Novusun? For each axis, it has Pulse +/- and Dir +/-, no 5V output. The stepper drives that I have only takes a 5v input and step and dir (see attached image). Is it possible to wire these drives to the controller?

    Many thanks 🙏.

    It should work if you provide 5V to the drive + pin (5V needs to have a shared gnd with the controller), then only connect the step/dir - outputs to the drive Step/dir inputs.

    Guess I'll need to get a 5v supply because there is nothing on the controller :(.

    Thanks for the reply!

    Check the COM+ pin for 5V

    If you need a 5 supply then a USB wall wart is a quick and cheap solution - old phone charger.
