hello, so i'm trying to make a stepper motor move more than 100000 steps.
still new to this... so i was trying "long" variables but the stepper moves about a 1/10 of the steps and stops. i also set up an array
long moveArray[]={144000,100,1600,1600,1600,1600,1600,1600,1600,1600};
and tried calling it with
rotate(moveArray[0], .5);
and
rotate((long) moveArray[0], .5);
but again the stepper didn't move the right amount of steps on any large number.
i'm basing all of my code on this:

rotateDeg(-360, .1); //reverse

delay(1000);
}
void rotate(int steps, float speed){
//rotate a specific number of microsteps (8 microsteps per step) - (negitive for reverse movement)
//speed is any number from .01 -> 1 with 1 being fastest - Slower is stronger
int dir = (steps > 0)? HIGH:LOW;
steps = abs(steps);
digitalWrite(DIR_PIN,dir);
float usDelay = (1/speed) * 70;
for(int i=0; i < steps; i++){
digitalWrite(STEP_PIN, HIGH);
delayMicroseconds(usDelay);
digitalWrite(STEP_PIN, LOW);
delayMicroseconds(usDelay);
}
}
void rotateDeg(float deg, float speed){
//rotate a specific number of degrees (negitive for reverse movement)
//speed is any number from .01 -> 1 with 1 being fastest - Slower is stronger
int dir = (deg > 0)? HIGH:LOW;
digitalWrite(DIR_PIN,dir);
int steps = abs(deg)*(1/0.225);
float usDelay = (1/speed) * 70;
for(int i=0; i < steps; i++){
digitalWrite(STEP_PIN, HIGH);
delayMicroseconds(usDelay);
digitalWrite(STEP_PIN, LOW);
delayMicroseconds(usDelay);
}
}
any ideas to how i can call a larger number and make it move that amount of steps?
many thanks!
