Someone told me here in local market that go for servo motor with brakes and servo driver for z axis. Because when you do 3d carving zaxis carves .01mm to 0.001mm and stepper motors are not able to run fast to do this

What's your opinion


3D carving a piece of wood does require many moves in all axis. However, the Z axis usually follows the controls of the object being cut, so think of a animal like a horse, so it will follow the contour of the horses body, moving up and down as it sweeps across the work piece. While servos might be able to respond faster, honestly many people do all kinds of 3D carving using stepper motors and they work fine. Focus on the issue with your machine, you can always upgrade to servo motors later after you have much more experience.

I just check z axis move exactly 25mm up and down from start to finish. So steps of motor is correct.

Do I need to check backslash too ?
