Exploring Creality K1 Pulleys: A Guide to Optimal 3D Printing Performance

Welcome to the world of Creality K1 pulleys – the key to unlocking optimal performance and precision in your 3D printing journey. Discover how replacing the stock pulleys with high-quality alternatives can significantly reduce VFA (Vibration Frequency Amplitude) and enhance your printing experience. Unveil the steps to elevate your Creality K1’s capabilities and delve into the realm of smoother, faster, and more accurate prints.

Creality K1 Pulley Replacement for VFA Reduction

Creality K1 Pulley Replacement to Reduce VFA:
There have been reports that replacing the stock pulleys on the Creality K1 with smaller, higher-quality ones can significantly reduce VFA (Vibration Frequency Amplitude). Here’s how you can go about it:

  1. Replace the Pulleys:

    • Swap out the stock pulleys with Mellow 20T pulleys. To remove the old pulleys, you can print a special tool (available on Printables).
    • Smaller pulleys don’t limit speed and allow for higher accelerations because the motor load is reduced. With the same torque, you can achieve theoretically higher accelerations with the 20T pulleys compared to the stock 36T pulleys.
    • The printer can easily reach speeds of up to 800mm/s during travel moves.
  2. Adjust Firmware Settings:

    • Rooted firmware is necessary for this step.
    • Change the following settings in the firmware for both X and Y axes:
      • rotation_distance: Set to 40 (instead of 72).
      • driver_SGTHRS: Increase to 110 (instead of 65).
      • interpolate: Set to False (instead of True).
      • microsteps: Increase to 128 (instead of 32).
      • run_current: Adjust to 1.2 (instead of 1.5) unless you want extremely high accelerations (30k+).
  3. Additional Notes:

    • The K1’s model fan isn’t very balanced and adds micro-VFA at speeds above 30%.
    • Consider making the flanged bearing gantry project for further improvements.

Remember that this is based on community experiences, and your results may vary. Some users have reported skipping issues with the stock gantry when using 20T pulleys, so be mindful of that

Key Features of the Creality K1 3D Printer

The Creality K1 is a 3D printer that offers a range of features for enthusiasts and creators. Let’s delve into its functionality:

  1. Extrusion and Filament Handling:

    • The K1 uses a pulley system to drive the filament from the spool to the extruder. These pulleys ensure smooth and consistent filament movement during printing.
    • The extruder pulls the filament through the hotend, where it melts and deposits layer by layer to create the 3D object.
  2. Layer-by-Layer Printing:

    • The K1 follows a layer-by-layer printing process. It deposits material (usually plastic filament) in thin layers to build up the final object.
    • The pulleys play a crucial role in feeding the filament accurately, ensuring precise layer alignment.
  3. Belt Tension and Movement:

    • The K1’s pulleys are part of the belt tensioning system. Belts connect the printer’s moving parts (such as the print head and bed) to the stepper motors.
    • Proper tension ensures smooth movement along the X, Y, and Z axes. The pulleys help maintain tension and prevent backlash.
  4. Z-Axis Movement:

    • The K1’s Z-axis movement relies on pulleys and lead screws. As the print progresses, the build plate (heated bed) moves up or down.
    • The pulleys ensure precise vertical movement, allowing for accurate layer height adjustments.
  5. Bearing Support:

    • Pulleys often incorporate bearings to reduce friction. These bearings allow smooth rotation of the pulleys, minimizing wear and tear.
    • The K1’s pulleys contribute to the printer’s overall stability and reliability.
  6. Maintenance and Lubrication:

    • Regular maintenance involves checking the pulleys for any debris, dust, or wear. Clean them with a dry cloth to maintain optimal performance.
    • Lubricate moving parts, including the pulleys, to prevent friction-related issues.

Key Benefits of Creality K1 Pulleys for 3D Printing

Let’s delve into the benefits of using Creality K1 pulleys for 3D printing:

  1. High-Speed Printing:

    • The Creality K1 is designed for speed. It boasts a maximum 3D print speed of 600mm/s and an acceleration of 20,000mm/s². This makes it one of the fastest 3D printers in the entry-level market.
    • The incorporation of a CoreXY motion system enables efficient handling of high-speed printing. Unlike traditional Cartesian-based systems, CoreXY uses stationary motors and lighter moving parts, resulting in quicker movement of the print head.
  2. Quality and Stability:

    • Despite its speed, the K1 maintains solid print quality. It runs Klipper firmware, which compensates for vibrations during printing, reducing defects like ringing and ghosting.
    • The direct drive extruder with a circular ceramic heating element ensures precise temperature control, contributing to better print quality.
    • The triple lead screw 3D print bed design enhances stability during printing.
  3. User-Friendly Features:

    • Automatic calibration and hands-free bed leveling make setup hassle-free, especially for entry-level users.
    • Preset slicer profiles in the proprietary ‘Creality Print’ slicer allow users to start printing right out of the box.
  4. Enclosed Design:

    • The K1 sports a sleek, die-cast aluminum frame that provides the rigidity needed for high-speed printing.
    • Its fully enclosed design includes a tempered glass door, tinted acrylic side panels, and a removable polycarbonate top cover. This makes it ideal for printing with materials like ABS.

In summary, the Creality K1 offers a compelling combination of speed, quality, and user-friendly features, making it an excellent choice for both beginners and experienced 3D printing enthusiasts.
