It has to do with how big the machine is. If they separate the extruders more the x travel would need to be lengthened so both extruders can hit all spots on the build plate. Also as you increase the x travel bars the more they can sag in the middle due to the extruder weight. That brings up some more issues, a wider space between the extruders means the extruder assembly will weigh more and that makes more weight to move back and forth, more weight to stop/change directions, etc. You would probably have to slow down the travel or the belts will skip. It is all a trade off. For now until I need to do dual extrusion I have removed my left extruder stepper motor. I haven't increased travel speed yet but I intend to eventually to see if I can gain some print speed due to the lighter extruder weight.
