Paul,
that looks like it might be a post from SheetCam, and here is how I have modified mine to do something like you want. Obviously, you might want to change some of the parameters, but this works.

function finish()
-- endz = safez
text (" T0\n")
text (" G00 Z4.5\n")
text (" G59\n")
text (" G00 X0 Y0\n")
-- rapid()
-- endy = 0
-- endx = 0
-- endz = 5
-- rapid()
text (" M05\n M30\n")
end

As I use fixtures, I want mine to end at my "tool change" origin and I use G59 for tool changes. YMMV, but I think you can get the idea. By the way, Luna (sheetcam post language uses "--" for commenting.
