First code for oscillating motor...Be gentle!

Yes, that's how it is now ( if you change 10->0 )

But you must do that in loop():

// Include AccelStepper Library
#include <AccelStepper.h>

//Define motor pin connections
const int dirPin = 2;
const int stepPin = 3;
const long targetPos = 5000;
// Define motor interface type
#define motorInterfaceType 1

// Creates an instance
AccelStepper myStepper(motorInterfaceType, stepPin, dirPin);

void setup() {
  // set the maximum speed, acceleration factor,
  // initial speed and the target position
  myStepper.setMaxSpeed(350);
  myStepper.setAcceleration(50);
 //  myStepper.setSpeed(250);   // This is useless, as .run() only follows maxSpeed!
  myStepper.moveTo(5000);
}

void loop() {
  // Change direction once the motor reaches target position
  if (myStepper.distanceToGo() == 0) {
    if (myStepper.currentPosition() == 0) {
      myStepper.moveTo(targetPos);
    } else {
      myStepper.moveTo(0);
    }
  }
  // Move the motor one step
  myStepper.run();
}
