Multiple extruders required!

I have been investigating the best electronics/firmware combo for multiple extruders, I really need 3 extruders minimum to do the experiments that I am interested in, on closer examination of the electronics comparison table

it looks like we have a new contender that is for the first time quoting that it supports 3 extruders! Phoenix

Great, so off I went to join the TVRRUG (Thames Valley Rep Rap User Group) so that I could post on their forum and investigate how true these claims are.

I have the feeling that although the cool looking electronics set they have developed may well support 3 extruders in principle, unless they have already recoded the Marlin firmware then it is unlikely to directly support the additional (3^rd) extruder (I think Marlin supports 2 natively although I am not sure on this)

Anyway I had a very nice response from one of their moderators asking why I was interested in their group considering my (relatively distant) location, after explaining my reasons for interest in their electronics set I am now awaiting final confirmation of my account so that I can get posting on their forum.

A fair few electronics sets can support 2 extruders but not since the old days of using the RepRap Host (remember that!) did the host program natively support multiple (more than 2) extruder configurations, I really also need to experiment with some different software configurations rather than just staying safely where everything just works (i.e. with Pronterface and SFACT)

Maybe I could use RepRap Host now I have the firmware issues sorted (i.e. I am using Sanguinololu with Marlin FW) although I think development of this software set stopped some time ago.

There are several other configurations of electronics and software that I need to investigate, I noticed recently that there is a new PRO electronics set available (not cheaply though) R2C2 electronics this set although not cheap can print at extremely high speeds.

And I need to play with a Ramps set as this seems to be extremely popular and is quoted as being feature rich, I also think I could mill the boards for this set.

I have been asked to build a couple of 3D printers for a friend so I may get a chance to investigate more on this front depending on which electronics sets they choose.

The Pheonix Set has some great build instructions on their website also which should aid the construction process significantly.
