Drill Offset

[nat_wheatley]

Can anyone tell me what's wrong with my drill offset file, I've posted it below. I'm working in mm and it's giving me an offset that's about 13 mm or so too much.

Nat..
Run the "drill offset" file. Then type [U] [L] to list the current variables. Next, click the button to write a variable file. Save that file and see if you can figure out which variable is not working as expected. If you cant figure it out, post the variable file.
