The video is sped up a little so it will be clearly visible, As you can see there is some "wobble" between layer jumps. Is that normal?



They used a ridged coupler so any warping in the Z screw will be transferred to the motor. The sheet metal the motor is mounted to is weak in my opinion and allows the motor to pivot. This is actually a good thing as it keeps the motion away from the build platform. So I would not worry about it. I am pretty sure they all do it to some degree. If you build a tall object then home the Z you can see the wobble then. Since the platform has dual  smooth rods it will take some force to move the bed in a horizontal direction.
