Hi,

I've bough the DYS BLG3SN in order to build a handheld gimbal with the SimpleBGC 32-bit controller (updated to the last firmware). My first test was to try the motors and I successfully drive the Pitch and Roll motors in fluid motion driven by a joystick. I do this with PID values of low (P = 1, I = 0, D= 0). The problem is with the yaw motor that motion is not fluid, every 10 degrees or similar there is a "shake". The motor is the DYS BGM4108-130HS. I'm using a Sony NEX 5N with the 18-55mm kit objective.

- I tested with different power values because I was thinking that the problem may be was related to the cogging of the motor
- I configured to 22 poles as the datasheet specifies
- I tested with smaller mass in the gimbal to test if it was a problem of load
- I checked the resistance of the three phases and its quite similar
- I tried to move the centre of gravity to different positions with the same result
- I tried to change in the configuration the pitch output to the yaw motor with the same result

I don't know where may be the problem. Any suggestion?

Thank you!
