Strange problem with PWM control in ANGLE mode
Is there any idea for my problem? I'm a bit scared to wipe out eeprom because I'm not quite clear with what sequence I'm going to pick up the system again.

Strange problem with PWM control in ANGLE mode
...and if I change inputs for YAW, analog A1, 2,3 or PWM RC or FC, nothing change, but if I change from angle to speed mode all inputs work!

No, at any speed, 10,20,100... and any acceleration limit same problem. Something is wrong in mapping on Alexmos. Question is where, software bug or hardware. Tomorow will erase eeprom.

Can`t figure what is wrong. Now I am put analog potentiometer on A2 but same problem. In angle mode yaw not moving but in speed mode work normaly. https://youtu.be/qzTzIKx1DqY youtube: https: //youtu.be/qzTzIKx1DqY (delete space betwen : and // )

Roll and Pitch signal inverted
Re-calibrate the gyroscope and accelerometer. Watch out for the correct orientation axis of gyroscope! The only way to replace it axis is faulty input ! ( GUI-Basic menu-Sensor-Axis TOP: RIGHT: ). Try with AUTO detection.

Update from 2.43b9 to 2.50b2
I have changed the PID value and now is better. On my gimbal manifested as sometimes overshooting and sometimes trembling in the target position (followed by high sound from yaw motor). Now have not overshooting but yaw axes motor sometimes tremble …

Interference of the external enviroment?
CFarg, I had sometimes more, sometimes less I2C errors, for no obvious reason but after changing cables I have no errors!

Slip rings - experiences
MShekunov, good question, but it is more about that I do not have to worry about wires when I transport or put gimbal in case. I have slip ring on yaw and work good, but think about put on other two axes. Major problem (if is) is IMU wire which hang…

Dead band only in speed mode?
I'm sure it still affects the angle mode, because when increase the dead band increases and idling of potentiometer around a central position. I will contact support.

Haha, thanks AOPEN3434. I am put one on yaw axis and think put on roll and pitch axis also.

Because sometimes I want to have tilted image. But that is not point, my question was like above because it bothers me dead band in the middle of the potentiometer.
