Hi Farmer
Your video has been done with Flash, but Flash is now unacceptable to all latest-version web browser as it has far too many security holes - STILL. If you want others to be able to view it, you need to change the format from Flash to HTML5. Not my doing, just the way the web has gone.
Perhaps you could summarise your video in text, here? Closed Loop vs Open Loop vs Rotary Encoder vs Linear Scale would be interesting, but the titles hide a mort of other choices and restrictions.
Cheers
Roger
