OK, I am building an antenna tracker somewhat similar to an Eagle Eyes Pan & Tilt. Similar in that it uses 2 gears to get ~360° yaw rotation. I am using Hitech HS-485HB servos on both pan and tilt. The yaw motion has a 2.16:1 gear ratio and using the servo’s max rotation of 190°, I should get ~ 410° of rotation. I am only getting about 285°. I have set the servo limits at 900 and 2200 on the servo test screen, and that is all I get for rotation. I could print a different gear set, but they are already getting big. When I check the physical limits of the servo, it goes about 180-190°, and when on the tracker I get a fair bit more than 360°, but that is physically rotating the tracker.
So I think I have 2 options:
find a way to get the servo to go to 190° of rotation. Can Ardutracker do this?
Go to a continuous rotation servo and redesign the gear set…
