Hello,
I am currently working on GPS pointing with a Gremsy MIO. I’m using ArduCopter 4.3.3 and latest MIO firmware version which is 7.7.2. I will attach a little video to explain the problem I’m facing.
The gimbal is configured according to the information available online on the Ardupilot website and Gremsy documentation. Mount type: Gremsy + Synchronous mode (in GTune). The main problem I have encountered is that there is an angle action cone that prevents from moving the gimbal between +/- 40 degrees in pitch and +/- 40 degrees in yaw. Outside of that, the gimbal moves correctly.

As you can see in the video, everything works correctly with the gimbal set at 45 degrees pitch and yaw. However, when yaw is changed to a range less than 40 degrees, the gimbal is zeroed directly on that axis. The pitch remains at -45 degrees.
Then, the pitch is changed to a range less than 45 degrees and the behavior is identical. It goes to its zero directly. You can check in GTune desktop this event.
Then you set both axes back to ranges above 40 degrees and the gimbal is perfectly positioned again. We have tried to change parameters inside GTune to see if we could modify how it acts, with no success.
Have any of you faced a similar behaviour or could give me any clue on how to abord this issue please?
Thank you in advance.
