Ender 3 Series Product Upgraded Dual Z-Axis Synchronous Belt Kit

This product is suitable for the Z-axis upgrade of Ender 3, Ender 3 Pro, Ender 3 V2, Ender-3 NEO, and Ender-3 V2 NEO. There are slight differences in the installation of copper columns for Ender-3 NEO and Ender-3 V2 NEO. Ender 3 and Ender-3 NEO require different methods to secure the power supply.

Product Features:

Upgrades the machine from the original single-rod drive to dual synchronous belt drive.

Issues it can address:

1. Inconsistent height on both sides of the machine's X-axis components. 

2. Possible lag in transmission during the up-and-down movement of the Z-axis by the X-axis.

3. Regular layer patterns in printed models caused by the non-straightness of the lead screw in some machines.

Product limitations:

1. The original filament rack cannot be used, requiring an alternative method for the filament rack.

2. After the upgrade is complete, the Z-axis might experience downward movement when the power is cut off. (Slight downward movement can also be observed in the installation video.)
