thingiverse

# miniprusa MC3 v1.0 ## FDM/FFF 3D printer project Heavy Duty, small factor, cartesian (bedslinger) machine capable of printing high detail plastic prints (PLA, PETG, TPU and possibly ABS, ASA, other high-temp materials). Project is loosely based on Bearmod project for Prusa i3. Utilizes out-of-the-shelf components and 3d prints. ## Features - ~100x100x110 [mm] build volume - Direct MK3s extruder [remixed] for MK8/HobbGoblin drive gear and filament sensor (switch) - Popular [Bearmod] XZ axis design, inverted - LM8UU and 8mm smooth rods linear guide - Rigid metal frame out of steel plates, 2040 and 2060 aluminum profiles - Dual Z axis is driven independent with 1:2 gear ratio with nema 17 motor for each side - [Marlin] 2.0.9.1 with auto bed leveling - Custom ergonomic controller with OLED and encoder ## Technical details ### Frame Frame consists of 2040 and 2060 aluminum extrusion profiles with 6mm groove. Steel plates and 3 printed bars (front, back and top) are holding extrusions in place secured with M5 screws and t-nuts. ### XYZ drive Nema 17 stepper drivers for all axes. GT2 belt and pulleys. Dual Z axis consist of two trapezoidal screws with 8mm pitch (TR8x2) driven by independent motors with 1:2 gear ratio (GT2 T20 and GT2 T40). ### Extruder Extruder is simplified PRUSA MK3 extruder with HobbGoblin/MK8 drive gear and 624ZZ idler bearing (PRUSA MK2s style). Very consistent extrusion ;) ### Electronics Currently project uses RAMPS (https://reprap.org/wiki/RAMPS_1.4), as it is the most common mainboard. Power supply should be at least 200W PSU is not mounted on the frame as printer was supposed to be in enclosure. ### Additions Two types of cable tubing hoses 10mm (X,Y axes and OLED controller) and 16/17mm (extruder) ## Firmware Marlin 2.0.9.1 (v1.1) binary included ## Project Development For more files, issues and if you want to contribute visit project github page: https://github.com/JGxFTW/miniprusa
