TornadoCube - Tevo Tornado CoreXY Conversion

thingiverse

The TornadoCube is a CoreXY printer using the Tevo Tornado as the donor printer. It uses electronics, hotend, extrusions wheels, bed and motors from the Tornado. Additional parts and extrusions to convert to CoreXY are listed in the BOM. Download the build summary PDF for more details on the printer. It is inspired by [Tech2c’s Hypercube](https://www.thingiverse.com/thing:1752766) design. The belt arrangement follows the general layout of the Hypercube design with modifications to suit movement using V-slot wheels. It also uses some of the concepts such as using slots rather than holes to bolt parts to the 2020 extrusion. Build area is 300x300x400mm same as the stock Tornado Extrusions ---------- Stock V-slot extrusions: * 2x 560mm 2040 * 2x 460mm 2040 * 1x 410mm 2020 * 3x 400mm 2020 Required 2020 extrusions: * 4x 435mm (left-to-right frame beams) * 2x 560mm (Vertical beams) * 1x 410mm (Heatbed back beam) * 2x 405mm (Heatbed side beams) * 1x 322mm (Heatbed front beam) * 3x 185mm (for electronics box supports) BOM --- Most parts can be bought from BangGood. The closed belt, 36 tooth 8mm bore pulleys and 2020 T-slot can be bought from a few places - I just used Ebay.
