Hi guys, I have been lurking for a while after finding Openbuilds while looking at CNC routers. So I need some advice from you awesome people, because I cannot work out what I want/need. Basically I want to do a few things with a router, 3d machine foam cores for composite parts, Machine plywood and other wood to make various things, possibly put into production machining either plywood or foam, so I would like it to be faster than average. I would like at least a 1200x1200 cutting area, that way I can do a sheet of plywood in two operations if needed. Obviously 1500 extrusion would be used. I also want at least 200mm of Z axis working area (more is better) for doing big 3d parts etc. I reaaaalllyy like the idea of C-beam, for the small price increase it seems to be a lot stiffer and stronger than standard extrusion. Do I need 1500mm lead screws? or will I be fine with gt3 belt? I know for foam the belt would be fine but can I get enough stiffness to do plywood kind of fast? I really like the OX and OX metal by Schematix. I would really appreciate any advice, I have a rough idea but I don't want to build a machine that wont do what I need, then have to re design. Cheers guys, Sam!
