Tool bit offset

[AngelT]

When cutting a "square" with Mach2, the dimensions both X and Y are short by almost 0.200"...the line is cut inside the square. How can I program it to cut outside the square? Thanks for any imput...

Change the code to allow for the tool diameter.

Kipper,

I ran your code through Vericut. Worked like a charm.
