Remixed Belt-Driven Z-Axis Mod for BIQU B1

Remixed Belt-Driven Z-Axis Mod for BIQU B1

This is my adaptation of the Belt-Driven Z Mod originally designed for the Ender 3 by Kevin Akasam (link to original mod). I modified the design to fit the BigTreeTech BIQU B1 printer using a belt-driven Z-axis kit from Aliexpress (kit link).

Changes and Adaptations:

1. Right Bracket (V3.7)
   • Adjusted the bolt location inside the bracket, moving it 0.5 mm further from the extrusion for proper alignment.
2. Bottom Part
   • Redesigned to ensure it could be securely mounted on the BIQU B1's extrusions.
3. Z-Endstop Switch
   • Fixed using the left screw of the clamp mounted on the left plate, positioned close to the extruder.
4. Z-Endstop Adjustment Screw
   • Utilized the right screw from the bottom part and added approximately four washers for proper alignment with the switch.

Notes:

The kit I used was a great fit overall and required minimal modifications beyond the changes listed above.

If you're looking to upgrade your BIQU B1 with a belt-driven Z-axis, this remix provides a practical solution.
