Tilt servo is grinding / making noise

[dwblair]

The screw holding the camera tray onto the tilt servo spline has to be very tight. It is the only thing that connects that end of the camera tray to anything. But if it is too tight, it can interfere with the servo operation and make the servo labor all the time. It will make a grinding motor noise constantly. If you hear this, try loosening that screw just a bit.
