new stepper motors wiring mess...

Help again! My repaired motion board, replacement Gecko 210 driver
and new stepper motors arrived. I assembled them all but installed
only one stepper motor to the Z axis for testing.

I talked to the Anaheim Automation factory person to get advice on
the wiring for the Gecko drives and his new motor. It is wired
bipolar in series and is rated at 4.9 amps. It is one of the new
square Nema 42 high torque motors.

There are 2 windings wired in series together on one side of the
motor and another 2 windings wired in series on the other side. I
was instructed to connect one end of a set of series windings to the
Gecko phase A and the other end to Phase B then connect the second
set of series windings to Phase C and D. This is exactly what I did
on the original Bridgeport motor and the Gecko burned up! I told him
this but he thought it would be correct.

So on I merrily went according to the plan and it was apparently
wrong. Luckily I had purchased a backup powersupply for the setup
and it recognized an overload and shutdown before (I hope) ruining
the Gecko drive. I wonder if I can just switch Phase B and C wires
as I did before and get it to run.

I just don't understand why both the Gecko instructions and the
Anaheim Automation instructions describe the same wiring method and
it does not work. What am I not understanding here?

Thanks! (again)

HEART FELT APPRECIATION! I think I will get to the bottom of all
this eventually, but not without a lot of help from my new CAD-CAM-
EDM-DRO friends! The advice, insruction and suggestions given so
far have saved me from giving up and are truly appreciated!
