I have a Precix 9000 that uses stepper motors. There is a problem
with the z axis if the z axis speed is too high, the motor height
starts to slip.

I recall I was doing a 1/2 inch deep 2" x 2" cutout in foam for
practice and was puzzled to see it started 1/2 inch deep and ended
1/4 inch deep at the end.


I was told to turn down the z speed. But that converting to servo
motors would also solve the problem.

So I second the question, why do companies say that servos are
better? Marketing?
