Getting accelstepper to work with bipolar motor

[Unhinged Reprisal]

Hello,
  This is my first attempt using the accelstepper library. My motor jerks and doesn't turn smoothly. I have a 6 wire bipolar stepper. I must be over looking something simple. I tried it with all of the examples using the FULL4WIRE. If I read the library correctly, it seems that FULL4WIRE is used for unipolar steppers. How would I get it to work with a bipolar using 4 or 6 wires on 1.8 deg step angle motor?
Thank You For Your Time,

Hello,

Do you mean your stepper has 6 wires, and the stepper consisting of 4
windings, wired in pairs with a centre tap:

a
|
-/\/\/\---/\/\/\/---

b
|
-/\/\/\---/\/\/\/---

ie the 'Typical 6-Wire Unipolar/Bipolar' from
http://www.stepperworld.com/Tutorials/pgBipolarTutorial.htm


I connect these with pins a and b to ground, other pins connected to arduino
outputs, and initialise like the examples:

AccelStepper stepper; // Defaults to AccelStepper::FULL4WIRE (4 pins) on 2, 3,
4, 5

you have to be sure the sequencing of the pins 1, 2, 4 and 5 is correct

Cheers.
