hy, so you have the renishaw, but you can not locate the holes with it ? thus you can not use the renishaw ?
is there something that you can do with your renishaw ?
a renishaw may be programmed in different manners :
... software installed on :
...... cnc, created by renishaw, or by another software provider; this interactive software may not always allow you to use the probe at it's best potential, thus always check for updates, and decide if you need the update, because is possible to not need advanced gauging procedures
...... pc, thus a computer application
... g-code; this requires knowing the codes that make your probe tick
... osp api application ( should be free, but requires api :

so, this i why i asked you if you can use your renishaw; if there is something, maybe i can help you edit those soubroutines, so to create a program zero & rotation after measuring a few holes; i need the basic hole measuring g-code to be available, and after that is needed a method to read the results; i have done this before, and maybe i can help you / kindly
