No more layer shifting

Since installing this kit, my layer shifting issues on the Z-axis have vanished. The coupler absorbs minor misalignments very well. Great purchase.

Smooth Z-axis movement finally!

This upgrade kit completely eliminated the Z-wobble on my Ender 3. The lead screw is straight and the coupler fits perfectly. My prints are much smoother now.

Perfect fit for CR-10

I was worried about compatibility with my older CR-10, but everything lined up perfectly. The dual machine setup is stable and reduces vibration significantly.

Great value but instructions could be better

The hardware quality is excellent for the price. Installation took a bit longer than expected because the guide was vague, but once installed, it works flawlessly.

Essential upgrade for serious printing

If you are doing tall prints, this is a must-have. The electric Z-axis upgrade makes layer consistency incredible. Highly recommended for any hobbyist.

Solid construction

The metal feels premium and the threading is precise. I deducted one star only because shipping took a week longer than estimated, but the product itself is top-notch.

5 FAQ

Q: Will this work with the Ender 3 V2 model?

A: Yes, this kit is fully compatible with the Ender 3 V2. You may need to adjust the mounting bracket slightly depending on your specific frame configuration.

Q: Does this kit come with the stepper motor or just the screw and coupler?

A: This kit includes the lead screw, flexible coupler, and mounting hardware. The stepper motor is not included and should be sourced from your existing printer or purchased separately.

Q: Can I cut the lead screw to a shorter length if needed?

A: While the screw can be cut with a hacksaw, we recommend using the provided standard length for optimal stability. If you cut it, ensure the ends are filed smooth to prevent coupling issues.

Q: What tools do I need for installation?

A: You will typically need a set of hex keys (Allen wrenches), a screwdriver, and possibly pliers to remove the old components. No specialized machinery is required.

Q: Is lubrication required before installation?

A: The screw comes pre-lubricated, but applying a small amount of PTFE-based lubricant after installation is recommended for long-term smooth operation.
