PRODUCT DETAILS

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.

Perfect! Just Need the Z-Axis!

Bought the dual Y-axis rails awhile ago for my S1 pro and now installed the X-axis rail. Followed all the directions, including cleaning the rails with IPA and then greasing them lightly. I used Mobil 1 Synthetic since that is what I had on hand. Everything moves smooth with the Sonic Pad printing at 160ms. No vibrations. Love it! Just need the Z-axis rails!

Absolutely fantastic kit

I am so happy I made this purchase. I had nothing but issues with the crappy wheels on my X-axis and this seemed like a perfect solution. I spoke to a local expert on 3D printers and he recommended Gulf Coast Robotics. I ordered it and had the kit within 3 days.

Installation was very easy. One thing I recommend, soak the rail in IPA and squirt some into the bearings liberally to remove the shipping oils. If you leave the oil on it is a dust magnet and it will cause debris to get into the bearings very quickly causing it to feel rough as it moves on the bearings. After that use a good lithium grease to lube them up.

I took my time installing, putting loc-tite on all the screws and it still took under 20 minutes.

The main issue I had with the wheels was that they seemed to shed some kind of black dust that would collect to the point it would throw off my mesh leveling. I swapped out the wheels and that seemed to fix the issue for a few days, but then it came right back. I am brand new to 3D printing and it was literally a month of tearing my hair out trying to fix these issues as I didn't even know linear rails existed. Once I saw them though I knew they would be the answer to my problems and boy were they. Now when I do a mesh level I find that my bed is actually extremely level, with very small deviations. Before they were much larger, and would actually change almost daily as those crappy wheels shed whatever they were shedding.

Anyway, this kit instantly resolved all of that and even made my machine quieter. Thank you, GCR!

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.

Best x-axis kit out there but the supplied rail is meh

I bought this along with the full y-axis kit for S1 pro and the Gulfcoast-made parts are top notch. I just wish that there was an upgrade option to buy a more legitimate linear rail with this kit. The rail that it comes with feels gritty and catches when you slide it back and forth with your hand and the machining is very rough. I did install it though and it functions. I have some Hiwin rails and bearings on order from an automation parts supplier that I expect to be much better.

Hi Nolan,

Thank you for the feedback. I'm sorry to hear that you're not satisfied with the linear rail. We tested around a dozen different suppliers in this price bracket, compared them side by side, and chose these as the best available. They've even made further improvements at our request, upgrading the ball bearings to G10, tweaking preload, etc.

To your point though, we reached out to an authorized Hiwin distributor for a quote. Even in volume the cost per rail was more than our entire kit. While this might appeal to some, we have to take that into account when making products for budget 3D printers, and using genuine Hiwin rails would have tripled the retail price.

That being said, the gritty feel you mentioned isn't uncommon. Factory grease protects against oxidation in storage, but it's also a magnet for dirt and dust. Prior to installation, we suggest a thorough cleaning with IPA and then re-lubricating with your choice of oil or grease. 3-1 oil and White Lithium Grease are among the most popular options.

If these don't meet your needs though, please reach out to us. We'll be happy to arrange a return and refund. Just note, the X axis kit uses a 320mm MGN12 linear rail, and being that this isn't a standard length, the supplier may need a customization request.
