Thanks for the info Jack,
I am just in the research stage for a 4x8 plasma table right now, but I do have a design rolling around in the back of my head. I plan on using rack and pinion for the drive, and either v-groove or bearings and maybe some square stalk for the guide rails. I think I can get away with driving the long axis from one side as long as i spread out the guide bearings far enough on the drive side,and make the gantry light enough, there shouldnt be any chatter on the undriven side.I am just trying to get an idea of how much everything is going to cost before I jump into it with both feet. |
