James, looks like the code that BR549 provided did the trick.  My code would have programmed the entire board rather than using simple code and subs.    Simple is probably better!!  And with his code you can cut and paste values to produce whatever board you may need.

However, if you are still interested, I will code it and post a copy.  Up to you.  Most of us on here are usually eager to demonstrate our talents (probably more like manic-obsessive-compulsion    ) when it comes to solving some cnc-machining task.

o1
M98P2 L1     (calls The sub to create a row, calls sub 2 and repeats 1 time)
G91             (Sets Inc mode)
G0 Y1          (After each row it increments the Y one space(1"))
G90             (reset to abs mode)
M99             (returns to sub call)

o2
G91           (sets Inc mode)
