It's just that it depends what you mean. You say you want EMC to control your spindle, but do you want to control the speed? or really control the spindle position in relation to other pieces of your mill, as needed for rigid tapping? In any case, you have to figure out a way for the computer to talk to your spindle, and the details depend on the particular spindle drive setup, of which there are million. So, what is your spindle drive, and what do you want to accomplish? ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
