How to make a certain number of steps with a stepper per second?

Question

Arduino

I have two steppers, I use the accelStepper library, I need the steppers to move 300 steps, wait for example 3 seconds and move 300 steps again, the closest that I managed to do this, but after a while the int overflows and everything stops working.
I know that there is a setCurrentPosition method and you can set it to zero in each cycle, and then ask to take steps to point 200 and so on again, but if I set the point as zero at the end of the cycle, everything also stops working, so I use a strange addition please tell me how to do it right

AccelStepper stepper1; // Defaults to AccelStepper::FULL4WIRE (4 pins) on 2, 3, 4, 5
AccelStepper stepper2(AccelStepper::FULL4WIRE, 6, 7, 8, 9);

int position = 0;
int last_time = 0;

void setup()
{  
    stepper1.setMaxSpeed(300.0);
    stepper1.setAcceleration(100.0);  
    stepper2.setMaxSpeed(300.0);
    stepper2.setAcceleration(100.0);
    last_time = millis(); 
}
void loop() {
   position = position+300;
   stepper1.moveTo(position);
   stepper2.moveTo(position);
   stepper1.run();
   stepper2.run();

   if (millis() - last_time >= 3000) {
      stepper1.stop();
      delay(1000);
      last_time = millis(); // сброс таймера
  }

}

Answer 1

setMaxSpeed ​​- this is "a certain number of steps per second", i.e. speed
A instead
stepper1.moveTo(position);
in your case it is better to use
stepper1.move (300);
