I just had an email from Bruce, and it apears that his clock pulse is about 3.3V, and he is using a laptop.
This is most definately the problems, and is actually quite common when a laptop is used.
The solution would be to use either another laptop with higher voltage outputs, or a desktop PC with a parallel port.

Bruce,
Try this and give us your results.

Thanks

Gary

Gary from Motion told me that the SW4 was meant only for dropping current down to half after a phase but I'm so lost now I'll try anything.
