By default, Ender3 V2 has only one lead screw on Zaxis. Adding another screw will make this printer more reliable on higher printing speeds and make that angle between X and Z axis closer to 90°. Dual Z axis upgrade is almost mandatory if any weight is added to hotend (for example direct drive extruder). This package was sent to me by Banggood for a review. Since Cleality manual is only on one page, I decided to create a detailed assembly and wiring video. You can download this Creality manual from:
