That way I have drilled half way thru the pcb for a thru hole, turned the board over and drilled from the other side, meeting in the center of the boards thickness with perfect registration. Auto location was to the center of a small brass pipe just out of the lower left corner and at a known offset. That mill died, and if I was to do it again today on the 6040, I'd have to invent a pinned location for the pallet because the extruded bed is such a mess, off Z as much as 1/8". So obviously its not been tried. > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users
