Again thks Wildbill. Well after 3 hrs its a no go. I can hear the servo motor working which is a good thing. So what happens is the mouth moves all the way up AND wants to go higher, but will not move down. The motor continues to run till you literally get out of Smaug device test. The mouth then relaxes about a 1/4 in but will move no lower, despite changing the values. Frustrating.
Update: I was about to send the post above and my tech after leaving my house for 15 minutes comes back. He has Steve from JJP on the phone.
Another Update...after being on the phone with Steve (who spent close to an hour on the phone...what a great guy), everyone is baffled as the mouth will only go up not down. This after we took apart the whole mech for a third time which as you say, gets easier.
Steve is going to send another servo motor. Not sure that's the issue as the motor stays engaged (till you drop out of the smaug device test). Unless there is something in the motor that prevents the mouth from lowering, its a mystery. Hope no one has to go thru this.
