The Review of: New HIWIN Original Authentic MGN12C MGN12 Linear Guide Rail With Slider High-Precision 50mm Linear Guide 3D Printer Alloy Steel Review

The HIWIN MGN12C Linear Guide Rail is a precision motion component designed for smooth and accurate linear motion in various applications, including 3D printers. Let’s delve into the details:

  1. Linear Guides and Their Benefits:

    • Linear guides facilitate linear motion by re-circulating rolling ball elements between a profiled rail and a carriage (bearing block).
    • The friction on a linear rail is only 2% of that of a traditional slide.
    • Linear guides can be loaded in all directions, making them versatile for various applications.
    • These features make linear rails a preferred solution for high-precision CNC machines.
  2. MGN12 Linear Rail:

    • The MGN12 is a smaller and low-inertia linear rail, constructed from stainless steel.
    • It is commonly used in 3D printers due to its precision and performance.
    • The linear rails can be employed on all axes of a 3D printer, whether it’s a cartesian or core XY design.
    • The most significant impact on printing quality occurs when improving the movement of the print head (either the X-axis or the XY-axis).
  3. Existing Printer Upgrades:

    • Enthusiasts successfully upgrade existing printers with MGN rails.
    • Many designs are available on platforms like Thingiverse for MGN applications on popular low-cost printers (e.g., Creality, Tevo, Anet).
    • The rails easily mount natively on the 2020 extrusion profiles of these printers.
  4. Advanced Designs:

    • Some advanced designs feature complete coreXY printers with linear rails on all axes.
    • For instance, the BLV printer incorporates linear rails and has become more affordable due to optimized bundle prices.
    • Other options include the Voron Design DIY printers, such as the Voron 2.4, which offers excellent performance-to-cost ratio.
  5. Upgrading Existing Printers to MGN12 Linear Rail:

    • When upgrading the X-axis of a 2020 extrusion-based 3D printer to MGN12 linear rail, consider the design of the X-carriage.
    • The new carriage should account for the dimensions of the MGN12 rolling block and the clearance between the fixation holes.
    • Fortunately, Hiwin provides step files to assist in this process.
