    Hi , Most of the time i have enough trouble printing with one extruder, but when i finally "master" this I would like to use multi-colour or multi-material for support material......
    So I was interested when learning about Prusa 2 and 4 material upgrade that they have for Prusa i3 MK2

    Original Prusa i3 MK2 Multi Material upgrade kit (preorder) - Prusa Research
    im not sure what electronics and firmware they run on the Mk2, but im hoping it will be compatible with my machine at some point (ramps , marlin)

    Otherwise I might use 2nd direct drive extruder, but probably not the best idea as my X axis is only 20x20 v-slot,

    anyhow , has anyone else liked the look of the system from Prusa ?

    if you havent seen it there is a video here-

    cheers ben

    hi snokid,
    good to hear you are getting this
    so will Prusa provide firmware that will be compatible with your electronics / will you need to adapt this firmware?
    cheers

    Good one Bob,
    I Imagine the Multi -material system is aimed at owners of MK2, and I should wait for it to come out to see if others adapt this system for non-mk2 machines.
    I just did small bit of research to find that mk2 has rambo-mini board, which is arduino mega shield
    reprap wiki says rambo board uses marlin firmware,
    so i imagine its just a matter of someone writing / adapting firmware so that Ramps could talk to the break-out board that Prusa uses to drive the 4 extruders,
    cheers
    Ben

    also Bob , i saw this ebay one you had link too as well , but not sure how to run it, i guess a Rumba board can run 3 extruders so no break out board needed,
    also i found this which is similar but has more information on how to do it
    Diamond Hotend - RepRapWiki
    this is where to but it

    yeah the color mixing is pretty cool!!!
    I have seen the diamond hotends before they are cool for sure...
    The rumba board is the way to go, by the time you mess with a stepper expander the costs aren't much different...

    this is going to be the year multi color/material that goes mainstream...

    yes i think that this is an exciting development.
    but just when i was about to get my machine working I feel the need to introduce a whole new level of complexity !!!!!!!!!
