So I am looking to put together a router and have heard that there are discussions comparing moving table vs moving gantry designs. From what I've gathered the gantry design is said to be easier to manufacture and less expensive. On the other side all that I've heard is that a moving table can be much more ridged but requires a much larger footprint. My biggest concern is the rigidity of a moving gantry design with a single lead screw and the possibility of rotation about the y axis. Wondering also where the the difficulty is greater to produce a moving table vs moving gantry. I can see using black gas pipe and skate bearings for both methods. Just hoping to have a discussion comparing the options as i couldn't find much of one up to this point.
