If there is not while, then motors won't spin. All they do without while loop, is one step.

Any while in your sketch is most likely wrong. loop() is called in a loop, that's all the looping
you need for a well behaved sketch where the different parts cooperate.

Place calls to stepper1.run(), stepper2.run() etc in the body of loop(), make sure loop runs
frequently by always returning promptly from it.
