6 Wire Stepper with Darlington Array guidance?

marksundt

Hi, I'm trying to connect a 6 wire hybrid (unipolor/bipolar) stepper motor to a Darlington Array and associated source code that drives Parallax 4-Phase / 12 Volt Unipolar Stepper and all I can get the hybrid stepper todo is bounce between two steps.

I thought this would be fairly straight forward if I connected the two center-tap (yellow/white) as common and used the remaining 4 wires to power the coils. (As seen in the attachment) But I'm afraid thats not the case.

I'm using the Stampworks example code for experiment #26

Steps DATA %0011, %0110, %1100, %1001
...
StepFwd:
sAddr = sAddr + 1 // 4
READ (Steps + sAddr), Coils

Any guidance would be greatly appreciated!

Thanks!

Mark
