Gecko connection to unipolar stepper??

Hey guys,

Here is what I have and what it's doing..

I'm trying to connect a 6 wire unipolar 3 volt 3 amp stepper to a
Gecko 201 drive.

With an ohm meter and a D size battery I determined which set of
windings are which.

A and a lead are I'm assuming one full winding. As the ohmeter shows
2.3 ohms across it. If I take either a or A lead to common I get
half the resistance. Hence, half the winding. I connected A to phase
A and a to phase B on the Gecko. Same with the other set of
windings. B to phase C and b to phase D.

Have 34 volts DC coming in. Power light comes on and nothing. No
smoke no pop no motion. I don't know if I have the step and dir pins
called out properly in the software. I'm checking that now, thought
that may enable it somehow.

Any input on this would be most appreciated.

Hope I didn't blow this thing...

Thanks, Ron
