I empathise with you @dmcke5. It can be quite patronising when you get a response like that. A while back someone asked me to take a look at his drone that had developed a fault. It had been returned from the service centre as an uneconomical repair, claiming it needed a new flight controller board, esc, and downward facing sensor. In less than five minutes it was back up and running as all it needed was a squirt of switch cleaner into one of the controllers gimbals.
As for your camera gimbal issue, do you have access to a test bench PSU? If you can power the gimbal separately from the Sparks electronics it may help in isolating the fault. I’m only hypothesising but from your description of the gimbal behaviour the issue maybe associated with the IMU and its associated circuitry.
Thanks mate, I have plenty of gear so I could easily power something up independently if required however all of the connectors are extremely small so I would first need to work out a way to safely provide power to them. I didn't think the gimbal would run independently though as surely the gimbal itself is too small to house the control gear for the motors? The impression I get is that the main control board handles all of the control side of things, leaving nothing but motors and sensors on the gimbal itself.
The IMU was damaged by the original owner when he attempted to rebuild the spark into a new housing. I replaced it with one from a guy on ebay that is parting out a spark. It calibrated up perfectly and appears to be working just fine.
Gimbals I've dealt with previously have had their own gyro/acc on board for positioning feedback, but I'm not sure if that's the same way this gimbal functions. Based on the naming of the calibration functions I used on the computer, I feel like it may be using hall sensors instead which would need to be incorporated into the gimbal motor section, which I've already replaced. Basically the only things I haven't replaced yet are the camera board itself and the spark main board. I'm willing to replace the whole gimbal if I think it'll solve the problem, but I don't want to keep throwing money at this thing just to find out its a faulty main board. Unfortunately I'm fast approaching the cost of a functioning, second hand Spark (which is probably what I should have done originally lol).
Appreciate the input.
