Once you enter the hole parameters, then going to (0,0)
indicates the next hole... ie after drilling a hole, hit
"next hole" button, and the display says (X,Y)... you handwheel
it over until it says (0,0) and you are at the correct next
spot (works for both rectangular arrays and bolt circle patterns).

Now if you are designing such a device, the user often does not
move to (0,0) exactly, maybe only within a count or two of it
in X & Y, so you have to be careful to keep a background counter
going, in order not to accumulate errors.

That seems more than adequate for your initial target.
