Cartesian Dual 3D Printer. Main Axis Features: * Z axis with two motors and lead screws for smooth, precise motion * Ramps, Mega2560, 5x DRV8825, LCD 12864, and ATX PSU components provide a solid foundation * Six Nema17 motors deliver powerful performance * Two mechanical end-stops ensure accurate positioning * Lead Screws with 8mm pitch and 2mm lead offer precise control * Spring couplers and Gt2 belt facilitate smooth motion * Pulley with 20 tooth Gt2 provides optimal gear ratio * Four 608rs bearings ensure durability Heated Bed: * MK3 Aluminium Heat-Bed offers excellent heat retention and even distribution * Extruder feed gear with 40T OD and ID of 11mm and 5mm respectively ensures smooth material flow Cost Breakdown: * Total cost: approximately 320Euro * MDF 12mm: a necessary component for the printer's structure Components List: * Two pieces measuring 450 x 450mm * Two pieces measuring 100 x 450mm * Two pieces measuring 100 x 426mm * Two pieces measuring 450 x 500mm (can be modified to 515mm for increased Z height) * One piece measuring 120 x 450mm * One piece measuring 346 x 450mm * Cost of components: approximately 9.40 Euro Design Considerations: * To accommodate the motors and extruder, the wood must be thinned or a slot created * A CNC machine can make this process easier * The printer's Z axis end-stop/height requires further consideration Printer Specifications: * Print build volume: 200 x 200 x 187mm (with potential for an additional 10mm with modifications) * Dual Bowden extruder system with a homemade hotend (still in development) * Temperature monitor for the electronic compartment ensures safe operation * Firmware used: Marlin (available in rar format) Print Settings: * Printer Brand: RepRap * Printer: SmartRapCore * Rafts: Not necessary * Supports: Minimal or none, depending on print requirements * Resolution: 0.25mm * Infill: 40% * Materials: PLA blue and PET-G white (for testing purposes) Custom Section: A small test of movement demonstrates the printer's capabilities.
