Any idea what it would take to get our MF printers using this? I can't imagine how color switching works, since a single nozzle design will require that the machine switch the color it is extruding BEFORE it needs the new color (at precisely the right moment) to flush the exact amount of excess material from the nozzle.

Based on this video it looks like the slicer must set up a junker part that is used to switch colors? The idea being (I think) that the junk part, a cube, is built along side the current object, layer by layer, and the slicer switches to this object for a certain length of extrusion when it needs to switch colors. Then it goes back to where it needs the alternate color within the original object.

what slicer?

Good question I don't really know how this is supposed to work. I've never played with dual extrusion. Will Slic3r do this? If not, I assume these guys must have a patch for *something* .

putting a wipe tower next to your part is pretty easy. How they are making the color switch happen on the wipe tower i'm not sure. possibly their own branch of cura or something. surprised it's not covered on their site.

How do you do a wipe tower in Slic3r? I could never figure it out.

Don't know of any way to do it in slic3r. but when ive made STL's from sketchup i have drawn them in.
