Thanks for the response,
I must not have been very clear with my wording, because I don't plan on having any of the hotends moving independently. The "dual x" and "dual y" motors would be for increased speed and better symmetry (pulling from both sides of the gantry, similar to the reason for repraps to push the z-axis from two sides). As far as I know, the QU-BD printer is single extruder, single hot-end... With no chance of collision.
I suppose on very large prints, a dual hot end (or 3, or 4) could lay down twice (or 3x, or 4x) the plastic at its designated offset distance. But that's not what I'm concerned about right now. I'm mostly interested in speed and accuracy.
Hope that helped clarify.
