dave, rick posted a pic yesterday on the google group. not sure if you saw it. the hot ends do look very close together so i would imagine the X has not shrunk in size by too much. hard to tell though. Thanks, Jim, I just searched for it. I've seen dual extruders that looked like they were designed...

Dale, did you get a feel for the effective x-axis dimension with the dual extruders? I envy that you got to take a look at the prototype!
