Upgrades for Pulleys on Creality Ender-3 V3 KE 3D Printer

The Creality Ender-3 V3 KE is a fascinating 3D printer that combines affordability, open-source flexibility, and impressive performance. Let’s delve into some details related to the pulleys on this printer:

  1. Y-Axis Pulley Upgrade:

    • The Y-axis stepper shaft length in the Ender-3 V3 KE is too short for a 40-tooth GT2 pulley with grub screws. If you’re looking to upgrade, consider using a common Nema 17 42-40 stepper motor with a 24mm long shaft (measured from the stepper body). Some users have successfully used a FYSTEC stepper designed for S1/CR10/Ender 3.
  2. Dual Z-Axis Pulley Belt Tensioner:

    • If you’re interested in improving the Z-axis performance, you can explore the Dual Z Axis Pulley Belt Tensioner designed by Kev608. This printable STL model helps maintain proper belt tension for smoother movement and more accurate prints.
  3. Filament Wheel Guide:

    • For managing filament spools, you can create a filament wheel guide. You’ll need an M4 screw and a 4x10x4 miniature bearing. The guide uses the original filament holder nut, and the insert can be pressed in or glued. The top nut requires support, while the rest of the components don’t. The Ender3_guide&wheel.stl file contains all the necessary parts.

Remember, the Ender-3 V3 KE is part of Creality’s ecosystem, offering an intuitive touch UI, real-time model preview, and impressive motion graphics of printing parameters. .

Key Advantages of Ender-3 V3 KE Printer

The Ender-3 V3 KE printer offers several notable benefits over its predecessor, the Ender-3 V3 SE. Let’s explore these advantages:

  1. Improved Y-Axis Pulley:

    • The Y-axis pulley on the V3 KE has been upgraded. Unlike the SE, which uses a pressed-on 20-tooth pulley, the V3 KE features a better-designed pulley.
    • The Y-axis stepper motor shaft on the SE is round and too short for a 40-tooth GT2 pulley with grub screws.
    • Additionally, the stock belt on the SE is of poor quality, which affects overall performance.
  2. Speed and Precision:

    • The V3 KE is impressively fast and precise in its printing capabilities.
    • It combines Creality’s vast ecosystem with ease of use and Klipper-assisted speeds, making it an excellent choice for those seeking both speed and accuracy.
  3. Silent Y-Axis Rails:

    • The Y-axis rails on the V3 KE are now silent during movement. In contrast, the SE experienced noisy Y-axis movements.
    • This improvement enhances the overall printing experience and reduces unwanted noise.
  4. Customizable Screen BEEP:

    • The screen BEEP sound on the V3 KE can be turned off, providing users with more control over their printing environment.

In summary, the Ender-3 V3 KE offers a compelling combination of speed, precision, and enhancements over the SE

    • Identify the pulleys that need to be installed. These are typically associated with the X-axis and Y-axis movement.
  4. X-Axis Pulley Installation:

    • The X-axis pulley is responsible for moving the print head left and right.
    • Locate the X-axis motor shaft (where the pulley will attach).
    • Slide the pulley onto the motor shaft, aligning it properly.
    • Secure the pulley using the provided set screws. Tighten them evenly to prevent wobbling.
  5. Y-Axis Pulley Installation:

    • The Y-axis pulley controls the bed movement back and forth.
    • Find the Y-axis motor shaft.
    • Slide the Y-axis pulley onto the motor shaft, aligning it correctly.
    • Secure it with the set screws, ensuring a snug fit.
  6. Check Alignment:

    • Rotate the pulleys by hand to verify smooth movement.
    • Ensure they are centered and not rubbing against any other parts.
    • Double-check the tightness of the set screws.
  7. Reassemble and Test:

    • Reassemble any parts you may have removed during the process.
    • Power on the printer and perform a test movement to ensure the pulleys are functioning correctly.

Remember to consult your official Creality Ender-3 V3 KE user manual for detailed diagrams and instructions. If you encounter any issues or need further assistance, feel free to reach out to Creality’s customer support

The T-Method: Ideal Mechanical Advantage (MA) vs. Effective MA

Let’s delve into the fascinating world of pulley systems and compare their performance. Pulleys play a crucial role in various scenarios, from rock climbing to mechanical engineering. In this analysis, we’ll explore how different pulley systems stack up.

The T-Method: Ideal Mechanical Advantage (MA) vs. Effective MA

  1. Ideal Mechanical Advantage (MA): This value represents the theoretical advantage gained from a pulley system if all components were frictionless. It’s calculated by considering the number of pulleys and how they affect tension.
  2. Effective MA: This accounts for real-world factors like friction and efficiency. It provides a more accurate picture of a pulley system’s performance.

Basic Analysis Steps:

  1. Schematic Drawing: Begin by sketching a schematic picture of the pulley system. Label each pulley (e.g., P1, P2) and denote their efficiency values (P) for brevity.

    • For example, consider a Z-rig system with labeled pulleys.


  2. Tension Analysis:

    • Each pulley doubles the tension in the rope.
    • The rope maintains the same tension on both sides of each pulley.
    • At rope grabs or tractors, the tensions combine.
    • The upward forces (input force F and anchor reaction 2F) must match the downward forces.
  3. Ideal MA Calculation:

    • Assume P1 and P2 are both 1 (no friction).
    • Calculate the ideal MA by analyzing tension changes due to pulleys.
  4. Factor in Efficiency:

    • Introduce efficiency values (P) for each pulley.
    • Multiply the rope tension by P whenever it runs around a pulley.
    • The effective MA is then calculated as: 1 + P2 + P1*P2.


  1. 80% Efficiency Pulleys:

    • If both P1 and P2 were 80%, the calculated effective MA would be:
      • 1 + 0.8 + 0.8*0.8 = 2.44 (approximately 2.44:1).
  2. 50% “Pulleys” (e.g., bare carabiners):

    • Effective MA: 1 + 0.5 + 0.25 = 1.75 (approximately 1.75:1).

Practical Application:

This analysis helps climbers and engineers compare different pulley systems based on their efficiency and real-world performance. For instance, using a Micro Traxion as a progress capture device significantly changes the system dynamics compared to an ATC in guide mode.

A four-bar linkage is used to model a belt system and determine if the ratio of pulley speeds depends on the inter-pulley distance.
