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.

Great service. All the ordered items came quickly and securely packaged. The different items were well labelled, and there was no confusion about which linear rail was for which mod. Outstanding purchase and upgrade experience. I thoroughly recommend Gulfcoast Robotics if you need to upgrade a printer they specialise in.

Linear Rail FULL HOUSE upgrade for Ender 3 S1 Pro

Linear Rail FULL HOUSE upgrade for Ender 3 S1 Pro
I have just fitted the X, Y and Z linear rail upgrade kits from Gulfcoast Robotics to my Ender 3 S1 Pro.
It now looks and performs like a machine designed by an ENGINEER, not like a machine designed by an ACCOUNTANT.
Many thanks to Brett for the support provided half a world away from me, here in Sydney Australia.
I am very tempted to repeat the exercise on my Ender 3 V2.

Bill Woodall
Great product and even better support!

I ordered this knowing that it was not fully compatible with my printer, with the advice of Brett I had to print two parts out and it works great! Very responsive as well.

Do not buy the inferer rails off of...

I made the mistake of getting a cheap kit off of Amazon and it was a mistake. I had a wonderful experience with a couple of other products from Gulfcost so I decided to give them my money and I'm glad I did. I can't say it enough "you get what you pay for" and the price point is right on the money for the quality. My Ender 3 S1 pro is now fully railed and flying -no more pom wheels for me!-


Customer service was fantastic. Delivered promptly even with a hurricane. The product is just exactly as described
