Hi. I am new to the 3D printers. Now I want to build a 3D printer with 3 extruders and only 1 nozzle. Which are the best electronics and software choices? I am starting to read the repetier firmware, is it possible to use repetier firmware and repetier host for my machine? Should I use 1 arduino for controlling XYZ and another for 3 extruders?
Any idea or pointing is greatly appreciated.

I am using a RAMPS 1.4 but it only have 5 motor controller, the RUMBA seems to be a good idea. I will try one, but I am not sure about the support for this board.Quote

Hi
Get yourself onto the reprap irc channel and talk with RifRaf, he has been working on just this for a while.
I believe he is using a [reprap.org] , 6 stepper drivers.
also see [www.thingiverse.com]
From what I see the software support for 3 color is primitive so far..

Yes, the G-code seem to be the biggest problem now. I need to extrude all of the 3 material at the same time, while controlling the total amount of material and the ratio between them. I do not know what G-code can help me do this.Quote

Yes you can use Repetier firmware as well as Repetier host to print with 3 extruders on one nozzle.
You only need one board with enough drivers for the motors (6 at least)
The G-code for the printing is the problem at this stage - you need to manually change the G-code in a text editor or use the LCD controller to change the feed from one to the other whilst printing (That is if you selected the right options in Repetier firmware )

So G-code can control multiple feed at the same time by setting the feedrate for each extruder (for example E2.24:2.24:2.24:15.89). I wonder is there any way to control multiple feed at the same time by setting the total amount of feed and the ratio between them? Or it is better to implement this in the slicer?Quote

Just mention that G-code can do it(multiple feeds at the same time) but not implemented in the firmware and the slicers. [reprap.org]
