Custom NF WobbleX WS8 / WS12 / WS16 Coupling for 3D Printer Z-axis T8 – Prevent Z Bending Rod Upgrade Leadscrew

INTRODUCTION

a simple device for your printer that eliminates any artifacts caused by your Z-axis. It’s being hailed as the last upgrade that your Z-axis will ever need as it provides amazing accuracy, repeatability, and low maintenance. We’ll check out how it works and why you might want to consider grabbing some for yourself.

WHAT ARE Z-ARTIFACTS?

This is also known as Z-banding or Z-wobble, and it can be caused by various factors such as inconsistent layer height, mechanical issues with the printer, or unstable printing settings.

Normally, to prevent these Z-artifacts and improve the overall quality of your 3D prints, you would have to ensure that your printer is properly calibrated and maintained. This may involve adjusting the Z-axis movement, tightening belts, checking for worn-out parts, and ensuring that the print bed is level and clean.

Just a slight bend in 1 of your leadscrews will create artifacts that you won’t be able to solve. Enter Wobble-X…

HOW DOES IT WORKS?

A typical 3D printer with leadscrews will use a T8 nut to connect the leadscrews to the X-rail. This makes a solid connection which allows any problem in your 3D printer or leadscrew to pass along to your prints resulting in Z-artifacts. There have been a few options out there to battle this, such as leadscrew decouplers and Oldham couplers, but none of these have proved to be a perfect solution so far.

The Wobble-X takes the idea of the decoupler further by using metal pins and metal balls that compensate for the deviation of your Z-screw nut under four axes, stabilizing your Z-axis and providing a smooth operation. This 4-axis movement allows the bed to stay stationary while the leadscrew can move or “wobble” as much as it likes.

This freedom of movement will allow you to even use bent leadscrews on an out-of-square 3D printer and still achieve perfect prints.

I should also add that the Wobble-X is meant for use with ballscrews as they are superior in performance to the traditional leadscrew. If you are unfamiliar with the difference, check out this article where we go in-depth on the topic.
