Physics. Your printing too fast. The change in motion causes too much force on the effector. In essence you can drop Accel and speed or increase holding torque on stepper drivers

make sure all the ball joint and nozzle are tight.
or try check the voltage.

As mentioned check ball joints and connection points. Have you checked motor current to see if it's the same as others?

Moving axis by hand too fast will damage circuit board

I replaced all 3 drivers on the board to new, double checked all the magnet balls screws, all looks good and still this problem remains.... the movie is printing in 30mms ....
