If I am cutting rows of holes, with simple or complex outlines, I always go the
the hole position, then use a subroutine to cut the hole. The subroutine always
begins with G92 and always ends with G92.1
First, you have to understand that HOME is different from
workpiece OFFSET.
G10 L2 or G92 sets a workpiece offset, and can set it in one
of 9 coordinate systems (G54 through G59.3). Touch off in
the Axis GUI also does this.
HOME is to set the limits of travel of the machine, and is
very useful as it will detect placement of workpieces that
exceed this travel BEFORE starting the program. Saves a LOT
of wasted time and materials. It also allows you to run the
same part day after day, once the fixture has been set up
once.
