  • Yep: Another unsatisfied customer. I seem to be having the same issue with the BED that others have reported. After hooking up my motor and power supply exactly as directed, it ran choppily for a few moments, then stalled. Then the board seemed to stop working entirely. Now, as soon as it’s powered on (with no motor hooked up), the LED glows momentarily, then dims, then goes out. What’s up with that?

  • I need to run a bipolar stepper motor (Minebea 16pu-m202) v e r y s l o w l y for hours at a time, off a battery. Is there any reason I couldn’t use a very simple, low-frequency pulse-generator circuit (using a 555 timer, for example) to run this driver?

No public wish lists :(
