Ender3 V2 has only one lead screw on Z-axis. Adding another screw will make this printer more reliable on higher printing speeds and prepare it for adding more weight to hotend (for example direct drive extruder upgrade). I already tested two stepper motor dual-Z system. It works perfectly (only pay attention not to move screws if motors are turned off). This new method synchronizes screws even when stepper motor is not powered, thanks to timing belt and pulleys. This package was sent to me by Banggood for a review, but there was no manual in the kit, so I decided to create this detailed assembling video.
