Twitching Servos on the AL5D Robotic Arm

The digital servos on the AL5D twitch for some reason. Any thoughts? See the attached youtube video. youtube.com/watch?v=9cm86jjtREE

Information, information, information!

Please post some closeup images of the SSC-32 so I can verify the jumper settings.

The image was emailed to me. It illustrated that the VL = VS1 jumper was left installed. This essentially shorted the 9vdc battery to the 6vdc wall pack. This depleted the 9vdc battery in short order, making it a poor power supply. So the SSC-32 powered only by the 6vdc wall pack was resetting over and over. :stuck_out_tongue:
