Dual extruder

So… Thinking I need an mp3dp v2 to accompany my v1, but I want dual extruders on it so I can use water soluble support material…

Any ideas where the problems will come from before I find them on my own?

It might make sense to increase the size of the frame so both heads can reach the whole bed. I’m assuming you’re thinking dual mk8, and some bowden setup? That’s as far as I’ve thought about it.

SeeMeCnc, and Prusa sell commercial versions as well. With this no real mods need to be made.

Careful with Bowden options and flexible filament, it tends to bunch up a bit when under pressure so retraction will have to be set large, which means slower prints.
