You can probably retain the hardware limit switches and just wire them also to LinuxCNC for monitoring purposes. LinuxCNC will f-error when you hit the limits anyway, but you might as well keep LinuxCNC "informed" of the limits. Hardware limits will be a comfort if the machine runs-away during tuning. -- 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
