Hi all, I'm a new Movi M5 user, but have been using for about 3 months now. It has been perfectly fine until today. I have two different payloads for the Movi that I have set up recently - one is a heavier camera (about 1.6kg) and one is a lighter payload (about 1.2kg). I have set up the CG and marked their positions on the gimbal cage for easy swapping between the two payloads on the move. This also means that their stiffness settings have to be autotuned separately and noted down. Today after running the heavier load on the Alta 6, I swapped to the lighter one, shifted the tray to the marked balanced position and changed the stiffness values on the Movi Windows app. What I did not do is to go to Systems tab and click Write Settings. I thought by changing the stiffness values in the app, the Movi would remember it after disconnecting. When I powered on the Movi, it went crazy and spinned quite fast in Yaw and Pitch directions. It probably made about two loops in pitch direction. I quickly switched to kill mode and checked the condition. After setting the stiffness values correctly, the Movi still won't function well anymore. The tilt axis oscillates crazily without any sense of control. I have checked all the wiring, did connectivity test - the wires are all still ok. In the app, I find that all the status are good, except that in the Attitude Chart, Roll is drifting steadily, while Pitch and Yaw values are dead at either 180 or -180 or 0. This explains why tilt would oscillate crazily - it has no readings. Funny thing is, when I click Reset Controller, it will reboot and at the initial phase of startup, I can see reasonable values in all Pitch, Roll and Yaw. But once initialisation is complete, Roll drifts (doesn't correspond to actual movement), Pitch and Yaw go dead. Has anyone faced this issue? I stay in Singapore and sending back to Quadrocopter would take too long. I have a project demo by this Friday. Please help! P.S. I have submitted this issue to Freefly support email and am waiting their reply.
