Hi, I have my large Cinestar sized hand held with DSLR working really good, but one thing eludes me. If I shut down, and come back later, or the next day and power on, I get excessive shaking and rolling of the motor axis.
Perhaps other have experienced this. I can get it all tuned and working, do shoot shooting with everything balanced and working flawless.
If I come back the next day and start it up - everything is still and level, I get oscillation, the motors start rolling, tilting, pitching. Then if I quickly load another profile it sometimes comes back into alignment or if I do a "Set Angles" button sequence while holding the bucking gimbal. I just want to figure out a way to start up a day later and not have it go crazy in front of my clients.
I have tried it with both skip gyro calibration at start up and not. It just seems to always go crazy only on start up the next time I use it. Perhaps it's trying to go back to the last position from the previous session? I have to continue to troubleshoot this to see if I need to always load a certain profile and do a gyro cal at start up. Someone said to put the gimbal on the deck, so the IMU is absolutely motionless and cal.
I still get this, but I jump into Joytick mode and it goes away. Someone told me this, but I have not tried it, Put Follow mode in Profile 1. Then in the GUI load profile 1. Now disconnect and power down. The gimbal should load into Profile 1 on power up from now on without the shakes. See if it works?
I have follow me on profile 2, but it starts on follow me. I think this is as profile 2 is the last profile that was loaded from the GUI. So follow me does not necessarily need to be profile 1 to start on it.
I have on profile 2 and working ok. I realized that the only profile where I can really check the motor inversion is here. I had shakes on it reversed one of the motors and solved the problem
Just push it back by hand the pitch if it does that. Make sure when u startup the camera is pointing straight forward, also can lean more to the back but not to the front downwards. I had this problem when i startup my rig and my camera was pointing a littlebit to far to the front, when this happend i pulled it back by hand and it was gone. Think its a flaw in FW or maybe because there is not feedback from a second imu like there is with the movi, movi doesnt use second imu but some sort of second mechanism to tell where the pitch and roll is by startup
We have found in 2.2 at least, that if you write a profile and power down, when you disconnect and power up it will be in that last profile. I just load my Joystick profile on startup and all is well. If I forget and it's starting in Profile 2 (follow for me), I just click the button once and all is good. Didn't try pushing the camera up on pitch, but will do that to see what happens.
