The nut is embedded in a timing belt and spins. For a large long 4 meter router you might need a belt drive but if there is a shorter axis the screw could work. Screws go up to about 1.5 meters in length What I found from others is that the quality of the rails and bearing is really what matters. Much as we lie to focus on the motors and rive, it is the rails that define the machine. -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
