Hi. I have had a few simple BGCs so am not a beginner at setting up and tuning. I have just made a night Vision camera and put it on a gimble that has worked fine with a Sony A5100. It is about the same weight as the sony. Spent days trying to get this thing to be calm. I can turn off any ONE axis and it stops vibrating. Have tried auto tune and manual - from one extreme to the other. Also changed power over full range. It has encoders. The IMU is slightly offset from the Z axis as you see in vid. Seems to be some cross-coupling like if I force to you yaw it changes pitch of camera - dont think it did that with sony fitted. Any ideas please.
