silent shield board pin locations?

Steve, I think I have found the problem. I loaded the newer sketch (v 1.05) and that seem to resolve the issue.

Steve, Just finished the large stepper clock (sp9) and have the speed jumpers set to 0100 on the shield board and the clock is loosing about 3 sec per min. I have read your thread and have it set as shown.

I don't know which stepper motor you are using for the one I have set the correct speed using the pins farthest to the right .

Here is a picture showing the pins if you use the recommended

Nema 17 Stepper Motor 0.9deg

Steve, the photo was a big help, thanks...

I did the out out in out from left to right it makes no difference clock is too fast, two rotations per minute.

What does MSB and LSB do which one slows the clock.

I should probably add a picture to the assembly guide to make it more obvious. Here is a picture showing the 4 jumper pins used with the latest algorithm. The left most jumper is not used.

The latest assembly guide has the following table:

SP10 with 400 step motors should populate the jumpers as 0010 which would be out, out, in, and out from left to right.

Steve, actually I am confused re which of the jumpers do what and where they should be to set the speed and direction of the stepper motor...should all jumpers other than those specific ones be removed when not debugging? thanks
