    Optimized-20160611_233026.jpg I used @Mike Kelly 's dual extruder carriage but I didn't have the ability to program the fans and keep the second hotend. Without a cooling system I printed the model on the right. Turned out poor.

    A week after the initial installation, programed the fans with an available pin on the ramps board and got the print result on the left instead.

    Looks sweet man. Good work

    Note. I think the R1+ moved the end stop with back to the x idler and not on the carriage. It was some R1'd that had that

    The larger ovals around the Bowden tube Inlet are there to let you run wires through. Not entirely necessary though

    The r1 plus doesn't have a second extruder stepper driver slot. It's hard wired into the z to run dual stepper drivers on it

    FYI I used the RRD Fan extender to add the parts fan. Costs a bit more and takes up the servo pin port. Which I know you're using for the LED's, but just another option

    so with the duel extruder main purpose is to print in duel color, would any of the people on this forum approve of this mod it seems very interesting the cost is a lil extreme but i think the application is wonderful, the 3d printer call the pallet, it was in concept in 2015 and it should start hitting the shelfs here soon price point is the cost of a new robo 3dr1 lol

    If multi color was the only benefit of dual extrusion then the cost IMHO isn't worth the effort over just painting. I grew up on building models and painting details is a pretty easy thing to do. Now where the beauty of dual extrusion comes into play is multiple materials. So say you are printing something that needs supports. You could you a filament that is dissolvable for the supports or something easier to remove than the main material. Or lets say you want to add rubber feet to something you are printing in PLA, that could be done with a dual extrusion system. These may not be great examples, but hopefully food for thought of what possibilities there are when doing a project like this.

    Great example of the potential for multiple materials printed at once. Really opens the door from just working with multiple colors.

    Yea,multi-material is a reason to use multi-extrusion.
    Multi-color doesn't excite me.

    I made some custom spools for work that we wind copper wire on, these need printed in expensive PolyMax PLA with some extensive supports. While Simplify3D makes support generation and removal easy, the PolyMax is still very tough to remove.

    I will be doing this dual extrusion mod soon with the fans so I can do the spools in PolyMax and the supports in cheap PLA that will snap off easily.

    Hey I love your videos Marquis Johnson, they really help with my project on turning my robo3D into a dual extruder. Can you please explain or make a video on what extruder you used to feed your filament to the chimera? Thank you so much this is all I need to complete my project.

    I just looked into your YouTube channel and saw that you have already made the video. Thank you again for posting all these videos they really helped solve my problems upgrading my printer. Any tips before I buy the Bowden extruder?

    What is a RRD Fan extender and how do you hookup the dual parts fan to it? Do you have to do any firmware tweaking or special little circuit like Marquis did? Looking for easiest way of inserting parts fan for duel extruder, couldn't find Marquis schematic for his parts fan anywhere.

    Hello, I was wondering if you could help me with the fan mod. I have a thread open over here if you wouldn't mind taking a look. :)
