Two Steppers, different VDC on Motor Shield v2

Post by mccarthybergeron »

Hi All,

I've run a Stepper Motor off of the Motor Shield v2 perfectly fine (which is a great product) for one project, but now doing something more complex with two planned steppers. Here are the links to the two I plan for this new setup:
Questions I have are:
  1. 1. Because I'm new to all this, from what I understand, the AMSv2 will allow for me to have both steppers turn at a constant speed (or varying constant speeds) simultaneously? Is it as simple as looking into a specific library for the function needed to do this?
  • 2. Will I be able to work two steppers with different VDC requirements when running them both simultaneously? I was wondering if the wall wart was a 12V that the 5VDC Stepper would burn out?
  • 3. Assuming the setup would be okay, what wall wart would you recommend I use to run these two motors at the sametime? It looks like maybe a 12VDC and something with the current totaling 1.1 amps or a bit more...?
  • 4. Any brand wall wart or place you'd recommend to shop for one?
Thank you for your time with my questions!

To control two motors concurrently, use the V2 motor shield library and the AccelStepper Library: https://learn.adafruit.com/adafruit-mot ... l-software

All motors on the shield use the same supply voltage If the motors are two different voltages, you will need to stack two shields. https://learn.adafruit.com/adafruit-mot ... ng-shields

In general, current ratings are stated as 'per-phase'. Most stepping modes energize two phases at a time, so double that rating to determine the minimum power supply size. https://learn.adafruit.com/all-about-stepper-motors/faq

These supplies would work for those motors.
