Controlling stepper motors on StepDuino

[Ray_M]

Hi Crew,

I'm new here and just got StepDuino and I had no experience with the Arduino system until yesterday.

I have attached 2 "Mercury Motor" stepper motors to the board, and want to control the forward and backward motion of both of them via a tiny Visual Basic program I can write. I can do that with only one motor so far, but not two - and if I connect both motors the one that worked just starts shuddering.

Can anyone point me in a good direction?

Hi Ray,

Are you able to post a photo or a diagram of how the steppers are wired up?

Thanks for your interest. This is such a great product.
I will prepare a photo or diagram if needed, but for now:

[EDIT]: Problem partially solved - back later.
