Multiple Steppers at the Same Time

Hello,

I have 4 unipolar stepper motors connected to my Arduino. I am using Motorknob to control them, but can only get one motor to activate at any given time. Is there a way to have two or more motors moving at the same time? Thanks

The following code moves 2 motors. It moves one and then the other- not both at the same time.

void loop() {
  // Step forward 200 steps:
  Serial.println("Forward");
  myStepper.step(200);
  myStepper2.step(200);
  delay(500);

  // Step backward 200 steps:
  Serial.println("Backward");
  myStepper.step(-200);
  myStepper2.step(-200);
  delay(500);

You can't move them at the same time, but you can alternate single steps to make it look like they are moving together.
