I still repeat, I can't find anything better than LinuxCNC to run my CNCs, and maybe you are aware that it is already possible to do via ethernet with a Mesa card http://www.mesanet.com/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
