Nema 23 Stepper Motor with tb6600 driver not moving a full step

Projects General Guidance

 for (int i = 0; i < stepsToMove; i++) {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(stepDelay);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(stepDelay);
  }

Do you want me to set the stepDelay to 1250 or should it be 625 since there are 2 delays one after setting the stepPin to High and one after setting it to low and they would add up ?
