PRODUCT DETAILS
MGN12 Linear Rails Kit for Ender 3 Pro and Ender 3 V2 coming soon. Subscribe to our Newsletter (in the footer below) for updates.
The MGN12 Linear Rails Precision Motion Kit replaces the motion system on the Creality Ender 3's Y axis.
Traditionally found on high-end 3D Printers, MGN12 linear rails have tight tolerances, low friction and require almost no maintenance. The rigid steel guide rail and ball bearing slide block improve accuracy and offer smoother movement. Mounted on top of the 2040 V Slot extrusion, it also eliminates concerns of poor machining that can otherwise impede motion.
This is in contrast to the stock Delrin v-wheel rollers, a POM plastic that wears over time. They frequently develop flat spots that bump as the heated bed moves back and fourth, causing inconsistencies that are reflected in the printed object. V slot extrusion channels that aren't perfectly straight can accelerate the deterioration.
MGN12 Features
- High Positional Accuracy: Gothic arch design offers four points of contact at the bearings, offering high rigidity and high accuracy.
- Long Life: Stainless steel components are durable and have little to no wear over time, compared to hard plastic v-wheels that degrade from repeat contact between surfaces.
- Low Maintenance: Machined from stainless steel, linear guide rails are resistant to oxidation and corrosion. Linear slides that are properly packed with grease have a low friction coefficient and decreases wear on parts.
MGN12 Packages
The MGN12 Linear Rails Precision Motion Kit comes in 3 variations. Those that wish to purchase the MGN12 Linear Rails from another vendor, or modify their original Y Carriage with the necessary changes may opt for a suitable package.
