Hi everyone. Have been having an issue with our tilt axis due to something with the servo. Not sure if it is a set up or a maintenance problem. The vids below should illustrate things a little better. This first video shows the problem: When tilting up the camera begins to shake to the point that it stops moving. The problem is amplified by faster movements and heavier payloads (the camera is balanced) In this video the tilt gain was set at 180%. In this second video the problem is seemingy solved by reducing the gain to 100%. This video is more to illustrate the noise made by the servo. Is this normal or indicative of a more underlying problem? Any help would be much appreciated. Thanks, Jack.
In the first video your gains are too high. The reason it works better tilting down is because it's not having to fight gravity. Your second video looks better although they still may be a tad high for these harsh movements. In normal flying they should be fine. The sound you hear is normal for the servo.
Could you also do a test to make sure that the camera/tilt axis mechanics are not causing the problem, Jack? Hold the tilt small pulley, and push gently up and down on the front of the lens -- there should be no perceptible "slack" in the system. If there is, check (a) the tilt belt is tight (only 2-3mm of deflection at the center point between the small and large pulley), and (b) that the grub/worm screw on the large tilt pulley is tight so that there is no play between the large pulley and the shaft.
