    I'm sure I'm not the only one that's run across this but in all the searching done by myself and a friend of mine we're not coming up with anything definitive. All I want to do is control the rotation of a stepper motor (NEMA 17/23) through XLights as part of my display. What do I need in order to make this happen? I'm running Ron's Holiday Lights 4 universe controllers and ESP Wifi sticks.

    Do I need to connect the DMX outputs on the controller to a DMX specific controller and if so - what is this controller? I've seen lots of arduino references - do I need to build up an Arduino to act as a controller?

    I've watched and rewatched the Canispater Christmas moving head light but he's using a Falcon F16v3 controller which may have capability my controller does not?

    yes u will need a controller like Arduino and maybe a dmx shield. that's controlled by a controller that's outputting dmx.

    the way I control motors in my display is Arduino but it gets its inputs from 2811 pixel signal using this controller http://www.hansonelectronics.com.au/product/2811dc15/

    Don't know about those controllers, link?

    Is the stepper motor just on off, or variable speed? If just on/off a cheap DMX relay board may be all you need if those (rons) boards have a dmx output

    Find Me On:
    The OP is talking about stepper motors which are a very different beast to servo or DC motors.

    The easiest way would be to find a stepper motor control board with DMX input and drive that with the DMX output on your pixel controller.
