Wiring a Motion Control Stepper to a Motion Control Driver to get smooth rotations.

Can someone please tell me how can I get a smooth running motor. What settings do I need and how will the wiring be for bipolar parallel.

I have a 40V 10A PSU and the Motors are wired as Bipolar Parallel to the Drivers.

Motors being used http://www.motioncontrolproducts.co....TH76-2808B.pdf

Drivers being used

Driver is currently set as 2 Microsteps.

They are wired as per the Motion Control wiring diagram.

Blue+Red to A+
Blue/White + Red/White to A-
Green+Black to B+
Green/White + Black/White to B-

But is this correct because someone else said that I have it wrong.

Currently the motor is running jerky like http://www.youtube.com/v/4gkLBOmZqJU

Do I need to change any of the jumper settings inside? Because at the moment its left as they arrived.

The DIP switches are set as
SW1 SW2 SW3 SW4 SW5 SW6 SW7 SW8 -> Off Off Off Off Off On On On
