Function arguments

 for (byte gpio = Rled; gpio == Wled; gpio++) {
    pinMode(gpio, OUTPUT);
   }

Did you mean gpio<=Wled ?

@will

I am currently looking at drop box. Never used it but I believe I will be able to get a URL.

@barrie 

Sounds good

@barrie 

Your problem is that the runToPosition causes each stepper to complete that operation before moving on to do anything else. Change it to ...

void yoyo(int segment) {
  long target = FullStepsPerRev / segment;
  stepper1.setCurrentPosition(0);
  stepper2.setCurrentPosition(0);
  stepper1.moveTo(target);
  stepper2.moveTo(-target);
  while (stepper1.distanceToGo()>0) {
    stepper1.run();
    stepper2.run();
  }
}

This will allow each stepper to step once inside the while loop and will appear to "share" the motion.

@will Thank you, that looked promising but there was no reaction. The steppers didn't blink and kept running. 

By the way, did the video link work OK? Its my first use of the dropBox.

@barrie 

Maybe change >0 to !=0 ? Very curious.

Dropbox says that it can't preview items with no datatype, so you have to download the object and then guess at it's type, rename it and then play it.

@inq Good advice, thanks. In your absence I posted a cleaned up version of my sketch along with a link to a video showing the latest problem.

Blinking steppers ? What ?

What do you mean they "kept running", I thought you said the problem was that one or the other would stop ?

@will Sorry. I assumed you had seen the video. I am fixing it. I will send another link so you will have a better perspective.

@barrie Try shooting the video in 640x480, NOT HighDef

@barrie 

So you're saying that replacing your entire module you with my entire module made no difference at all in execution ?

Did it not compile or reload properly ?

@zander  First time video on iPhone. Options are 4K or HD each each with 24 or 30 or 60 options. What is 4K 24? 

@barrie 4K 24 is 4K resolution at 24frames per second (movie standard) You need to drop the 4K down to something a lot smaller, 1028 might fit in 10Meg but there is no need for a hollywood blockbuster, just a simple VGA 640x480 will suffice

You will probably have to run the raw video thru a downsizer.
