Here is a printout of a drilling list. This i a common file format for
Tolls of this kind. "gerber-file"
First i a list of used tools and their sizes. 0.60 mm etc.

Then each tool and hole positions as x and y coordinates.

This file is transfered to my drilling tool and then executed one by one.
The first is allways the position check that drawing position zero
is the same as the pcb to drilled is the same.
As can be seen on the tool this is done and mantained with several
sensors and fixtures.
