From what @DJ has told me in the past, the servos need to be initialized to a value (position) before the speed is adjusted. The speed calculation needs that value as a starting reference. This is why most of our previous robots started at a calibration position (such as 90 degrees).

You got it. You’ll find more info in the ezscript manual

I will consider this answered. I still do not understand why when I put the slower speed first it solves my initiation problem. This keeps my robot from jerking to starting position. Just must be right by accident.

Thanks for explaining several of the things above.

If you do want to try a Google Search of the contents of the site, just add site:https://synthiam.com/Community to the beginning of your search.  As DJ said, you should see hte same results, although the result format will be different and perhaps more usable for you.  (the site: tag is useful in Google for other sites that don't have good internal search engines).
