One big problem I'm having with most common router designs is lack of space to put them. I'm living in a 45sqm appartment and really need to use every space I've got as effectively as possible. Most CNC designs waste a lot of room because they are simply a big table that you can't use for something else unless you misuse them as storage / working table and have to clean it up before every use. Because of that I thought about what would be a more compact design. For storage in small appartments the organizing specialists always hint to use the wall up to the ceiling. So why not do that with a CNC table too and make it vertical? If you buy wood panels in a home improvement store you might have seen their sawing "table". It's basically a saw mounted on a XY-gantry on a slightly tilted (10-15 degrees?) vertical system so they can lean the wood against it without having to worry about it toppling over. Having no experience with the Openbuilds parts at all I wonder how something like this could be build and what its pros and cons are. Some things that ran through my mind last night - while I was supposed to sleep. Should be as flexible as the Ox in size Vertical gantry - slightly tilted (15 degrees?) Belts for vertical movement will probably stretch fast, so lead screw? Could a counterweight help with lifting? Which axis should be vertical? Y to save on lead screw and motor? X to spread the vertical load on two sides? Which should be the longer axis? Does it even matter? I don't see problems with routers, but what about tools like drag knives? This would be called "vOx" - as in vertical Ox If I decide to build something like that I'd need to have a 1000 x 700 cutting area, so it would be a 1500 x 1000 equivalent Ox, right? Just a short disclaimer: I'm not even sure if I will be able to build one in the future because of money (and well - space ). It's just some idea I had and thought I'd start a little discussion on. So what do you guys think?
