Interesting setup. Certainly solves the issues of running long wires to the gantry and having to do something to keep them from wadding up and getting caught in the works. Chain can be less expensive that multi wire cable. I was thinking this arrangement must be quite a bit like an etch-a-sketch but that uses two crossed rods which are held at their ends by tensioned steel cable, no support tracks at the rod ends. For a plasma cutter where height control is pretty much irrelevant, that could work assuming the cables could be held tight enough. ------------------------------------------------------------------------------ Own the Future-Intel® Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
