Update 04-20-15 Posted in Instructions a Preliminary BOM. Update 04-12-15 Forgot! I should mention http://www.thingiverse.com/thing:430851, thanks for providing me with valuable resources as the chief engineer! Update 04-09-15 Added Plastic link Additional Info 04-08-15 The printable Volume is 240x155x170 I set a target of simple construction compactness and cost reduction while also striving for good print speed and precision. By adopting a mechanical CoreXY, an extruder type Bowden, and E3D v6 1.75 mm Universal Hotend, I achieved these goals. The structure is made from aluminum tubes with a 20x20 square section connected through plastic links. Certain parts, like the extruder http://www.thingiverse.com/thing:331371, were sourced from Thingiverse. The mechanical coreXY design was inspired by another project http://www.thingiverse.com/thing:651117.
