most all cnc's will move in three axis at the same time, this is not an indicator of 3d. there is no issue with me that the gerber is a good router, seen plenty of em! in this day and economy they are readily available at prices that are unheard of. i would advise what ever you get told private to bring it back here, even consider the ez router they have a good unit!
while the gerber is a excellent and expensive router they are virtually unheard of in the woodworking world and out side of 2d letter cutting and expensive artcam software sign making due to the propietary controller.
