CNC sofware does a much better job than that based on the actual
backlash you tell it. If you take the Excellon ouput and sort on one
axis (low to high for example) then that axis never reverses (assuming
you start drilling at the lowest coordinate) hence zero backlash on
that axis. Usually this feature is built into either the Excellon CAM
processor or the Excellon to G-code converter.
