Lukestruder - The E3D V6 bowden mount for prusa i3 (Anet A8)

cults3d

E3D-V6 mount designed for Anet-A8 Prusa I3. It should fit any other Prusa i3, including MK2, but testing is pending. What sets it apart: - easy to print: overhangs limited to 45°, no supports needed - utilizing 3D printing's power for a highly integrated design (only 3 parts) - (nearly) print&play design: printer tolerances considered optimal, chamfers added for smooth assembly and use - stiff non-over constrained mounts for hotend, fan, duct, and auto level sensor; everything stays in place - cable routing and cable-tie supports included - easy access to all components for maintenance - optional 5mm LED can be added for visibility during printing - The fan duct is designed to maximize airflow beneath the nozzle, cooling filament quickly. It's short and concentrates air where needed. - Upper linear bearings placed at a distance for increased stiffness. Remarks: - Slightly larger than original A8 extruder; no print space lost. Check compatibility with other printers. Parts required: - E3D-V6 Bowden Version - 3x SCS8UU linear bearing mounts - 3x LM8UU or Igus RJ4JP-01-08 (recommended) linear bearings - 18mm sensor (LJ18A3-8-Z/BX used for wiring; alternatives at https://3dprint.wiki/reprap/anet/a8/improvement/autobedleveling) - Bolts: M4x30, M4 nut, M4x10 hex socket, M4 washers (DIN 125), M3x20 hex socket, and M3 nut Fan mounting options: - with M4 thread tap, M4x25, M4x20, and M4x10, along with 3x M4 washers - or with 2x M3x25, 1x M3x40, 3x M3 nut, and 3x M4 washers (DIN 125) LED requirements: - white 5mm LED - 470 Ohm resistor - wires for connection to heatsink fan wires Marlin settings in configuration.h: - define X_PROBE_OFFSET_FROM_EXTRUDER 33 (X offset: -left +right [of the nozzle]) - define Y_PROBE_OFFSET_FROM_EXTRUDER -1 (Y offset: -front +behind [the nozzle]) Define probe boundaries: - LEFT_PROBE_BED_POSITION 35 - RIGHT_PROBE_BED_POSITION 200 - BACK_PROBE_BED_POSITION 170 - FRONT_PROBE_BED_POSITION 20 Define printer boundaries: - X_MIN_POS -8 - Y_MIN_POS -8 - Z_MIN_POS 0 - X_MAX_POS 220 - Y_MAX_POS 215 - Z_MAX_POS 240 Update: 15.08.17 - big strain relief added at the top - E3D air outlet improved
