The hardware need to be properly modeled. There are plenty of litterature available including for freely accesible on internet about electric motors. Static friction may be a problem but I think a properly lubricated machine have rather viscous friction which easy to put in a mathematical model suitable for control of machine. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
