But since you asked...

It's difficult for me to think of the concept of 'movement error' since we are so intolerant of any errors at all.  I think that is only possible for us because we use steppers to move and to know where we moved. Therefore we must assume we always move to where we commanded.  In a servobot with encoder feedback, they may command a movement to precise positions but they can be somewhat sloppy with it because of the motor physics involved, and they will use a PID to accelerate, decelerate, and guide their movement based on this real-world feedback.

In reality we do not  have an error-free movement, either.  We experience errors in the form of oscillation, "ringing" which shows up repeatedly on each layer near a sharp corner, for example.  But we can also experience real slip errors where we encounter too much jerk which causes the motor to skip a step or slip too far.  We control these with acceleration, and we try to limit accel to the level our printer can handle.
