Features:

Upgrade 3D printers such as creality Ender3/3s/ Cr-10/10s/ Ender3 V2  to dual z-axis to improve printer stability.

After the upgrade of dual Z axis, the x-axis rises steadily and runs smoothly, which completely avoids the bottom consumables stacking pressure, reduces the lamination caused by z-axis vibration, and greatly reduces the leveling difficulty and leveling times.

Use original T8 precision screw rod, it runs smoothly. All aluminum coupling and original 42 stepper motor are used, stable operation.
No need to weld or replace the motherboard, directly insert the one to two motor wire into the motherboard.

Compared with the upgraded double Z kit sold on the market, this kit contains a power fixed module, which no longer allows the power supply to be scattered freely to avoid electric shock and short circuit.

Installation Step:

1) Turn off the printer, unplug the power cord, then use a hexagonal wrench to loosen the two screws that fix the power supply, and then remove the power supply.

2) Install the coupler on the stepper motor and tighten the screws. Use hexagon socket screws and Z-axis motor bracket to fix the motor on the aluminum profile.

3) Remove all screws of the sheet metal pulley on the right side of the X axis.

4) Fix the Z-axis sheet metal with long screws and install it on the right-hand sheet metal of the X-axis. Screw the T8 screw into the nut of the coupler and tighten the screw of the coupler.

5) Install dual Z stepper cable to the motherboard, and connect two Z motors.

6) Install the Phillips screw and the boat nut on the power supply holder to install the power supply.

7) Place the lead screw bearing guide on the left and right sides of the X-axis aluminum profile and let the Z-axis rise to the highest position. If one side is uneven,turn the corresponding coupler clockwise.

8) Install the lead screw bearing guide and tighten the screws, paying attention to the alignment position of the mounting base.
