Da Vinci Jr Dual Extruder Bracket Upgrade

thingiverse

Dual mounting bracket that adds an E3D V6 or Lite6 to an XYZprinting Da Vinci Jr for full dual extrusion. Please note that upgrading your board and firmware to something like RAMPS 1.4 is required to support this, as it will NOT work with the stock XYZprinting firmware! For more information see my thread on Soliforum about my conversion: http://www.soliforum.com/topic/15273/howto-convert-da-vinci-jr-to-ramps-14/. You also need an additional bowden extruder and extruder stepper motor. I used the 3maker All-metal for my mod, but you can choose any brand you like. Print Settings Printer: Hacked Da Vinci Jr Rafts: No Supports: Yes Resolution: 0.3mm Infill: 30% Notes: The included model and SCAD files have "legs" that extend the height of the mounting bracket to the full height of the DVJr's quick connect carriage, but you don't need them. You can adjust your slicer settings to omit the bottom of the model up to the DVJr mounting blocks. You must print with supports because there are many overhangs on both sides that need support. I used pillar supports with a 0.3mm interface in Slic3r. Post-Printing Clean up the supports, disassemble your stock hotend, attach it and the new E3D to this bracket. Clip it in, wire it up, configure your firmware, and test it. The DVJr hotend can be adjusted up and down for fine-tuning your Z settings to match the E3D hotend, which is fixed in place for ease. Loosen the mounting screws just slightly, use a little pressure to move it in tiny increments, then re-tighten the mounting screws. Final X/Y calibration is tricky and will depend on your individual printer. I ended up with X:35.5mm and Y:2.7mm as my offset, which should give you a good starting point.
