The Smoothie Board is much better than anything else out there for the price!

DC42 is a sales person, his answer to everything includes purchase of Duet electronics....
The melzi board does not have enough stepper drivers to control any additional extruders, so additional hardware is required. Most simple is to just add an external stepper driver and plug it into your melzi. Also needs a heater and thermistor control for a full second extruder. so also needs a mosfet and a analog in pin.
The original design of the Mendel Tri-color does use a additional melzi as a slave to the primary controller... all firmware is already done.
Moving to a duet basically means you will have to re wire everything and start again with the configuration, yes it will work, but it is a huge investment, time and money wise.

@deckingman, I'm curious about why you gave up on the 3 printheads. I suspect that calibration -- getting them all equidistant to bed -- would be a big problem. I mostly would want a 2nd print head to print dissolvable support structures. Regarding the offer for selling your other printer, I don't think that would work well. I live in the US. And if your RepRap is like mine, it would be difficult/costly to ship across the seas without damage. But I appreciate the offer. :-)

What people are talking about is the *quality* of the board, not popularity. They *may* be correlated, but I suspect that price and popularity are probably more closely linked.

........................... People like @dc42 and @arthur convinced me that RepRap has no collaborative future.

The Duet is fully open source and based on the original RepRap firmware.

That's certainly nice, but no help for collaboration at all. Yes, people do fork their own thing. And that's it. Zero efforts to get such forks back into mainline for the advantage of everybody. Collaboration is a lot more than just forking.
If you want to see collaboration, look at projects like Linux kernel, Git, Gcc, Clang, etc. People fork there as well, but after doing so they make sure their work gets back into the main repo and aligns with the needs of everybody ... or they get forgotten.
I don't want to point fingers or insult anybody. This is just how things work here.
