Compatible with the stock S1 3D Printers as well as our MGN12 Linear Rail Precision Motion Kit (X-Axis).

The MGN12 Linear Rail Precision Motion Kit is a complete Z-axis upgrade for the Creality Ender 3 S1, Ender 3 S1 Pro and Ender 3 S1 Plus.

When it's time to replace those worn out old POM wheels, linear rails are often the preferred choice. A 3D printer's motion system plays a crucial role in the overall performance, where it's no coincidence that rails have since become the go-to option. Manufactured to extremely tight tolerances, they are exceptionally stiff and rigid, which in turn translates to less flex and higher precision. In short, this helps to eliminate defects for the best possible print results.

Designed to seamlessly fit the Ender 3 S1 frame, the kit features (2x) 350mm MGN12 linear rails, our black anodized aluminum side brackets with hex stand-offs, and all necessary mounting hardware to complete the installation. As with all of our linear rail products, this utilizes a form follows function approach, where there is absolutely no loss of build volume.

X, Y, & Z axis linear rails

I’ve been looking for a decent set of linear rails for my S1 pro for a while, I looked into cheaper versions from other less known seller and was not comfortable in purchasing them, then I came across Gulf coast Robotics and their kit, I am so glad I went for these, I now have X axis, Y axis & Z axis rails along with their new alloy bed with heater, my printer has never printed so well until these were installed, if you are in the market for linear rails, you will not be disappointed, and their customer service is top notch! Brett was brilliant at answering any queries I had… very professional and a pleasure to do business with, will definitely use them again!

Another Great Kit

I already had the X and Y kits from Gulf and was a little disappointed they were not carrying the Z axis at the time i was looking to upgrade. Searched else where and was quite disappointed in what I experienced. Sent a message to the crew at Gulf Coast asking if they thought about adding the Z axis to their product line. I was happy to receive a message within an hour, letting me know they were indeed adding the Z axis rail and it would be out in a few weeks. Knowing the other two kits were of great quality I waited. Today I installed the Z axis and I could not be happier. Simple instructions to follow and everything fit like it was supposed to, I was up and printing in no time. These are "plug and play kits", no drilling or making your own anything, everything needed is in the kit. The customer Service the GulfCoast crew provides is hands down one of the best I have seen. Don't bother going anywhere else for linear kits, this is the place if you are looking for quality and Great Customer Service.
