    The dual head extruder module Robo3D is using on the home page to sell the R2 to people, making them think it comes with two print heads.

    Yup - I too made part of my decision to buy the R2 based on the 2nd extruder expandability, but am now basically thankful they didn't release it yet since that allowed me to find out about the drawbacks of that setup and the alternatives in the meantime.

    I know NOTHING about 3D printing - and when I found out about adding the 2nd extruder - I COULDN'T WAIT to get it.

    Now that I've been wrestling with the Mosaic Palette+ and multi-color printing ... I'm happy to wait on the 2nd extruder.

    People new to 3D printing often seem to think that if one extruder is good, two is better. :)
    Not really the case for most printers and even on printers that is does work well it is a lot more work on the modeling and slicing side.
    Unless you need multimaterial it is usually easier to paint ...

    most times (even with a dual extrusion machine) when I need different materials its a serious pain to design. Basically flexibles dont stick to anything...you have to design in a "lock" into the design which then becomes the weak point. Its gets really crazy (and expensive) when alot of the times (imagine a tire) can be made in 2 pieces and assembled. dual color is nifty, I'm guilty of printing a ton of dual color stuff for clients to ooh and ahhh at :D but once those are printed, I dont print it very often :D
