So many devices we work on have stepper motors in them. It occurred to me that it would be handy to have a device to allow quick testing of whether the motor was working or not.
The user interface is really minimalistic. A switch selects whether the motion is continuous or step-based, and there’s one button for forward and another for reverse.
Quick and dirty, but I wish I’d had this years ago. It would have taken the guesswork out of troubleshooting so many things…
