Summary of Chocolate (pasta) Extrusion Module for Kossel 800. The chocolate extrusion module is designed specifically for the Kossel 800, a cutting-edge 3D printer. The module features a modified 28BYJ-48 stepper motor converted to bipolar operation and connected to an A4988 driver. This setup allows for precise control over the extruder's movements. To achieve optimal results, a large 100ML syringe with nozzle is used in conjunction with the extrusion module. The syringe provides ample space for chocolate or pasta mixture to flow through the nozzle, ensuring a smooth and consistent print. For prolonged print sessions, a 12V carbon heater is employed to maintain a stable temperature throughout the process. This heater ensures that the chocolate or pasta remains at a consistent temperature, preventing it from solidifying too quickly. Several videos demonstrate the effectiveness of this setup, with the first attempt showcasing some initial challenges and the subsequent success video highlighting the module's capabilities. Print settings for optimal results include: * Rafts: Doesn't matter * Supports: Doesn't matter * Resolution: 0.2mm * Infill: 50-100% The gears used in this setup were printed with Nylon, while the body of the extrusion module was printed with PLA.
