I guess you could lower the acceleration. Do you have an ulticontroller on your machine?

Also it's common for people to not insert the Z screw completely inside the Z coupler that connects to the motor. Look again at the assembly instructions photo - you should see very little of the non-threaded portion of the Z screw above the coupler.

How do you know for sure that it is missing steps? Can you explain in more detail how you determined this?
