I think that the reason is that it can be simpler to route wires to two sides of a moving gantry / moving motor setup than to engineer a cross-shaft. If the motor is stationary then cross-shafts make sense. But for the common moving-motor designs (and Racks / Servobelt are inherently moving-motor) the drive needs to be stepped-up through the gantry or down under the table and that can be awkward and increases moving mass and potentially introduces backlash. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
