Thank to http://www.thingiverse.com/thing:430851 for providing me the chief engineer Update 04-09-15 Added Plastic link Additional Info 04-08-15 The printable Volume is 240x155x170 In realizing this machine I have set a target of simple construction compactness and cost reduction as much as possible. But I also wanted good print speed and precision. I think I got a good result by adopting a mechanical CoreXY and an extruder type Bowden and E3D v6 1.75 mm Universal Hotend The structure is made with aluminum tubes 20x20 square section connected together through the plastic link. Some parts such as the extruderhttp://www.thingiverse.com/thing:331371 is taken into thingverse For mechanics (corexy) I was inspired by another project http://www.thingiverse.com/thing:651117 Print Settings Printer: WildRiver 240 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 Infill: 25 Instructions Preliminary All plastic parts are PLA made 25% INFILL recommended BOM: Square Tube 20x20x1 Structure parts: 4 Pcs. 415 mm (width) 4 Pcs, 260 mm (depth) 4 Pcs. 270 mm (heigth) Rectangular tube 20x10x1 Plate support parts: 2 Pcs 170 mm 1 Pcs 100m Smooth rods 8mm diameter X Rod 1 x 305mm 1 x 310 mm Y Rod 2 x 225 mm Z Rod 2 x 295 mm 11 x 608zz Bearing 8 x lM8UU Bearing 4x Stepper motor nema 17 4000g.cm 2x 20 teeth pulleys GT2 3 mt GT2 belt 4 x screw M8 50mm threaded rods z axis 1 x M6 210mm 1 x Aluminium Coupling 5mm (motor shaft) 6mm (threaded rods ) This part can be also printed see my things 1 x M3 threaded rods at least 300mm need to make the various parts; supports the mounting plate adjustments homing support J-head etc. electronics I used Arduino with ramps and 1.4 driver DRV 8825 sensors home, end stop mech 1.2 for z axis y axis for x-axis used a classic end switch Power Supply 220Vac to 12Vac 20A METAL J-Head HotEnd Bowden system Tube for Bowen system 4mm out 2mm type use for oil lubrification 600/700 mm
