Problem of Z aixs lead screw...

A. Because there is a small gap between the lead screw and copper nut, so they are not parallel before you install them to the printer. This has nothing to do with the quality of the product.

B. You can loosen the copper nut and adjust the position of Z axis motor to try to keep the lead screw and the lead screw are parallel when you assemble the printer, and then tighten the copper nut again.
