I'm still having a problem with the nick on my av-200. When I set to default in camera tab in MK tools and I set the nick to say 125 then it will work. But my slider on my RX to move the camera mount nick up and down won't work. But when I address the nick to Poti4 the manual nick works on the slider but will not move automatically. The roll continues to work fine. Any thoughts on this, please!!
