Wow! Thank you so much, Ben!
I know I'm new here but I had no clue you would be giving out the designs to this amazing concept.
I've been doing models of some figures lately for a charity auction, and having a dual headed printrbot based workhorse would have sped along the process emensely!
It's realy fun to know that the heads could be wired up that way and the board supports that power output. Your design could possibly also utelize what RichRap did for his Tri-Color printer, but it involves another logic board apparently.
Maybe its possible to wire in a switch er... with a regulator? That way if you only wanted to use 1, you could just flip the switch to dissable power to the 2nd motor and Hot End.
Sorry if I use the wrong terms, I dont know much about electrical engineering or programming hardware yet , the closest Ive gotten to logic like that is creating logic through pre scripted nodes inside of the unreal game engine.
I know the printrbot uses a heated platform, but would you be able to use two of those together side by side? or do you plan on just using half of an 8inch platform for each extruder?
Thanks again for the generosity and the amazing, entertaining, and informative show!
Have seen the files but fon't really know how to used them, specially the .ai one. I am currently working on building my own 3D printer and using this design or parts of it would definitively make the building easier and quicker. The parts i'm most interested in are the laser cut pieces which I have to adjust to work with my extruder, any ideas on where or how to get the file(s) to those pieces?
After watching part 3 of the double decker 3D printer, I have one question. Why did you use two motors for the z axis when one motor, two years and a belt or chain drive would have worked just as well? With two motors, if one motor fails, the chance for damage caused buy uneven t travel of the print heads increases. With one motor there is only one part to replace instead of two.
Just a thought.
