B-axis drive is damaged.
-
check your T axis as well.
-
Do you have some immages or a small clip of how this happens?
-
It may be your R axis casting is bent. Did the robot crash?
Replace the wrist.
-
What kind of move command did you use? MOVL, MOVJ,....
-
The fixed end of the B drive is attached to the R axis casting. If the R axis casting is bent, the B drive will not have a correct alignment to rotate on and as it turn it will cause the R axis to torque back to the correct alignment and cause this shake as it moves. If you don't believe me , make a job that only moves the B drive, slow, and then fast. you will see the 'shake' will correspond with the speed of the B drive motion. Thus, the B drive is pushing the bent R casting.

You can replace the R casting, but in my opinion you are better off replacing the whole wrist unit.
