Just 1/4 Revolution

hello ,

im using library code

code: [select]


  
#include "stepper.h"

// change steps variable number of steps on motor
int step= 25600;

// create , attaches stepper motor
// 100 steps pins 0, 1, 2 , 3

stepper stepper(step, 8, 9, 10, 11);


void setup()
{
  // set speed of motor 20 rpms
  stepper.setspeed(1600);
}

void loop()
{
  
  stepper.step(5120);
  delay(6000);
  
 
  
  }





with ardino uno + 8 lead stepper motor (unipolar connection)+ attached stepper drive

all connection code said when run motor motor rotate 1/4 revolution noted max accepted microstepping setup 6400 steps , when tried run code 6400*4 give me 1 revolution


why 1/4 revolution???

and best configuration , set .and need 1/128 micro step more accurate.
