I imagine that the "beam" is a lot stiffer than the "quill". You probably machine with the "quill" retracted as far as you can, but can still reach down inside things when required. > 2) Ok, there are ballscrews for Z and W axis. Where can I find some > more information about the hydraulic counter-balancing? Probably just a hydraulic cylinder with a pressure regulator and pump. With the regulator set to a pressure where it will almost, but not quite, lift the gantry the ballscrew torque needed to move the gantry is equalised. This is likely to make axis tuning a whole lot easier, and will also significantly reduce wear. -- atp ------------------------------------------------------------------------------ Beautiful is writing same markup.
