Improved X-Axis Idler Stack for Modix

This upgraded idler stack is designed specifically for the Modix X-axis and offers significant improvements in durability and stability compared to the original design. You can find the product here.

Why Upgrade?

The original Modix X-axis uses small bearings that wear out quickly, leading to reduced performance and potential issues with print quality. This new idler stack addresses these shortcomings by using larger, high-quality bearings commonly found in RatRig systems, making it better suited for heavy-duty usage.

Benefits of the New Design

Larger Bearing Size: Improves load capacity and reduces wear.

Enhanced Stability: Minimizes axial and radial play for a more stable X-axis.

Extended Lifespan: More robust components require less frequent maintenance.

Included Components

Bearings for both the front and rear idler stacks.

Bearings with and without flanges.

Aluminum shims and 3D-printed spacers.

Printing Recommendations

For best results:

Print the spacers solid for maximum strength.

Use a heat-resistant material to ensure durability under operating conditions.

Employ adaptive layer heights to achieve precise dimensions.

Assembly Instructions

To assemble the idler stack, follow this sequence:

Thin spacer.

Aluminum shim.

Flanged bearing.

Non-flanged bearing.

Flanged bearing.

Aluminum shim.

Thick spacer.

While assembling the new components, you may notice the fit is tight. Take your time during assembly to ensure everything aligns correctly. The improved performance and reliability will make the effort well worth it.

Conclusion

This upgraded idler stack is a must-have for Modix users seeking improved performance and reduced maintenance. With better stability, durability, and print quality, it’s an investment that pays off in the long run.
