The MGN12 Linear Rail Precision Motion Kit upgrades the X axis motion system on the Creality Ender 3 S1 and S1 Pro.

Traditionally used for industrial applications, linear rails are manufactured with tight tolerances, offering high rigidity, low friction and precision accuracy. In short, they are less prone to flex during use. When it comes to 3D printers, this ultimately means smooth and consistent movement that reduces, if not eliminates print defects on that particular axis.

The kit features our 4mm thick tempered aluminum back plate and adapter bracket, anodized black to seamlessly match the Ender 3 S1. Rather than replace the X axis, these bolt-on to the existing frame, providing a sturdy, yet lightweight solution to mount the 320mm MGN12 linear rail. Best of all, with a form follows function approach, there is absolutely no loss of build volume. The Sprite extruder assembly retains its original positioning to ensure full compatibility with aftermarket parts and printed designs.

Installation should take roughly 10 minutes to complete. All required parts, including the mounting hardware are included in the package. The assembly instructions can be found at the link below.

Well thought out system

Bought previous products from gulf coast. This is awesome product just like the other products. . Easy to install. Works great, great value as well. Customer service is by far the best I’ve ever experienced. Will always go to gulf coast for my needs on future printers.

Solid X-axis, best rail option for S1

Install was super easy. Quality parts. Simple design. No more worn down wheels. Quieter.

After switching out the Y-axis on my S1, I noticed significantly less ringing on that side of the prints. Seeing the same improvement with this on the X-axis.
