HCE beltless remix

thingiverse

Assembled and tested, my brand new HCE is fully operational. I've been fascinated by the concept of eliminating cumbersome belts and finally found a great starting point in xsvmfhzwg4416zp's awesome design. After some days, I discovered another long-desired tool changer at rajaa and thought, why not combine them to create my new HCE? No sooner said than done, here's the result. I made three key modifications to bring this project to life. Firstly, I opted for old T8 trapezoidal lead screws instead of the high-quality Helix lead screw, which was a cost-effective choice. Secondly, I relocated the X-axis below the 2020 profile, gaining approximately 80mm of horizontal space. Finally, I implemented the tool changer by adapting the extruder box to my preferred extruder, the XCR-BP6. The XCR-BP6 offers an efficient way to change the hotend without disassembling everything, requiring only two headless screws. For a detailed description, please refer to Rajaa's page. I've also designed versions for e3D-V5 and e3D-V6. I added support for both PTFE tube and wiring for extruder, utilizing a drag chain. You can easily add multiple tools with quick change, and all axes are equipped with anti-backlash. The optional cable chain shown is just an example. I'd like to express my gratitude to Rajaa, xsvmfhzwg4416zp, and OpenSourceClassRoom for their contributions. For more information about the whole printer details, please refer to its dad SCOTT_3D's Hypercube evolution. *Updates can be found at BOP* **BONUS** If you'd like to remix this design on your own terms, the entire project is available in Tinkercad at https://www.tinkercad.com/things/bW5H5Mp3UTn, where you'll find my entire project with other items not mentioned here.
