So here is the layout as of now (still very much in flux) A couple things were on my mind when I started this venture. The C-Beam design allows for a few of these. I need to be able to cut a 36" x 24" sheet. Want plenty of fixture room, for other projects. After the router is working properly I will add a second gantry that will have a laser. X axis rollers can be moved away from the chips and dust. (C-Beam lets that happen easily) In order to span greater lengths the Y axis needs stiffened. (Overhung loads need minimized) The X axis rollers not be under the extrusion (thanks to C-Beam). (Allows full length support) Design around Open Builds parts Keep plate costs down (waterjet patterns with secondary ops) Be rigid enough to support higher cutting speeds than the cheapo china routers I've had.
