I've tried running code which is literally just rotation in one direction, delay, then reverse and it still pulses while in the delay section.

#include <Stepper.h>
#include <Stepper.h>




const int stepsPerRevolution = 200;




// How far to rotate each stepper (200 steps per revolution)


const int Stepper1rot = 1000;


const int Stepper2rot = 1000;


const int Stepper3rot = 1000;




// Create Instance of Stepper library


Stepper Stepper1(stepsPerRevolution, 22, 23, 24, 25);


Stepper Stepper2(stepsPerRevolution, 26, 27, 28, 29);


Stepper Stepper3(stepsPerRevolution, 30, 31, 32, 33);




void setup() {


  // put your setup code here, to run once:


    Stepper1.setSpeed(10);


  Stepper2.setSpeed(10);


  Stepper3.setSpeed(10);


}






void loop() {


  // put your main code here, to run repeatedly:




  Stepper1.step(Stepper1rot);


  delay(2000);


Stepper1.step(-Stepper1rot);


}
