I've got everything connected properly, I'm able to communicate with the board properly too.
A couple things seem odd though:
1) When using the calibrate command "c" it appears that all 4 knee servos and the head tilt servo move.
The others don't appear to move (nothing is attached so it might just be that I can't see it. But I don't hear it either)
2) When I Validate, the knees will move to the 'stand' position, but only go just below 90 degrees for the 'rest' position. They do not move nearly as much as the 'resting' picture shows.
