Modelo 3D miniprusa MC3 - Cartesian Bedslinger 3D Printer por JGFTW no Printables

Descrição

DIY Project that utilizes out-of-the-shelf components and 3d prints.

Fusion360 model: [https://a360.co/3Ne5RhL](https://a360.co/3Ne5RhL)
 

Main 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
     


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](https://reprap.org/wiki/RAMPS_1.4)), as it is the most common mainboard.

Link to: OLED Controller with encoder project.

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)
