Large Prusa Clone 3D Printer ~ Green I3 Geni

thingiverse

Few months ago, I started to develop the Inmoov robot. Although the model have been designed to be implemented on small printer of 12x12cm platform, but the assembly of small parts requires a lot of shaping and abrasive. Large 3d printer would simply a lot of hard work and precious time. I looked around and the largest printer is the Creality CR-10 S5. I decide to build the printer with a build platform of 55x60x50cm. Unfortunately, I could not find a bed heater of that dimension, so I bought the 40x40cm 220VAC. A solid stated relay is controls the bed heater. The platform consists of 3 layers, the top is PEI 1mm sheet, then 4mm glass mirror, and the lower layer is 1mm aluminium sheet. All layers are sticked together with 3M double adhesion film. on bottom of the aluminium sheet the heater is sticked. The platform and the y-carriage weigh about 3-4kg, which would be heavy for 8mm linear rods, so i replace them with 12mm linear supported rail of CNC printers. The base is a plywood board of 900x800x16mm. The controller board is MKS GEN v1.4, with TMC2130 stepper driver, set @ 1.5V. The printable parts are made of ABS, most of them are Prusa MK3 or MK2 parts. The X-carriage has been modified to carry a BL-Touch type sensor. The Z carriage parts are modified to match the brass T8 nut. I included the bill of materials. The printer is working perfectly.
