12V Geared Bipolar Stepper Motor + Easydriver

hi,

i using 12v, 1.7a, 416 oz-in geared bipolar stepper motor sparkfun easy driver

the gears make sound , shaft shivers. doesn't turn. tried moving wires between , b nothing changed. worked stepper this?



thanks!

here code working with:

code: [select]

int dirpin = 2;
int steppin = 3;

void setup() {
  // put setup code here, run once:
pinmode(dirpin, output);
pinmode(steppin, output);
}

void loop() {
  // put main code here, run repeatedly:
 
  int i;
 
  digitalwrite(dirpin, low);
 
  delay(100);
 
  for(i = 0; < 1000; i++){
      digitalwrite(steppin, low);
      digitalwrite(steppin, high);
     delaymicroseconds(500);
  }
 
  digitalwrite(dirpin, high);
 
  delay(100);

  for(i = 0; < 1000; i++){
      digitalwrite(steppin, low);
      digitalwrite(steppin, high);
     delaymicroseconds(500);
  }

}

well motor wants 1.7a , give @ 0.7a....  did adjust the
easydriver maximum output current even?
