HCE beltless remix
Description
**Assembled and tested, my new HCE is fully functional** [picking/parking](https://youtu.be/5GJJPaBBFxQ), [printing](https://youtu.be/1yU55wIFVvs) clips** I've always been fascinated by the idea of eliminating that combersome (needing tensioning, prone to skip a tooth and so on...) belts and finally I found the awesome [xsvmfhzwg4416zp](https://www.thingiverse.com/thing:2929869)'s design a good start point. Some days later I discovered another long desidered tool changer at [rajaa](https://www.thingiverse.com/thing:2537454) and... hey! Why do not whisk them togheter and make my new HCE? No sooner said than done, here's the result. - The first mod was to make use of old good T8 trapezoidal lead screws, the Helix lead screw are the top of quality but my pocket said NOOOOOO! - The second mod was to move X axis below the 2020 profile, this way I gained about 80mm of horizontal space. - The third mod was to implement the tool changer; I adapted the extruder box to my preferred extruder [XCR-BP6](https://www.aliexpress.com/item/32839644652.html?spm=2114.search0104.3.22.3eff6246oYaNqJ&ws_ab_test=searchweb0_0%2Csearchweb201602_2_10065_10068_319_10059_10884_317_10887_10696_321_322_10084_453_10083_454_10103_10618_10307_10820_10301_10821_10303_537_536%2Csearchweb201603_52%2CppcSwitch_0&algo_expid=be80e02f-8161-4929-8ec8-9087ca585aa4-3&algo_pvid=be80e02f-8161-4929-8ec8-9087ca585aa4) that offers a fast way to change the hotend without dismantling all stuff, just 2 headless screws. Read carefully the Rajaa's page for detailed description. I've however designed versions for e3D-V5 and e3D-V6 - I added a support for both PTFE tube and wiring for extruder, making use of a drag chain. You can add several tools with quick change All axes are equipped with anti-backlash. The optional cable chain showed is only for example.
