Been reading through the TurboCNC manual in the tooling section trying to figure out how to set tool offsets. I can't figure out how to tell the tool which side of my line to offset to. Example, I have a rectangular piece with several holes to route inside it. I want to route outside of my perimeter lines, and inside my holes. How do I do this?

Do I have to set up differrent tools for each scenario?

Thanks

What you want to do is cutter radius compensation, which is G41/G42. TCNC does not yet support this. (They are working on it for the next release). What TCNC does have is cutter length compensation.

When it does have it, you use G41 in your code to offset to the left, G42 to offset to the right.

Hack,
TCNC doesn't have that kind of tool offset:( The tool offset in there is mainly for tool length compensation. You have to do that type of ofset either in your cad program or use a CAM such as SheetCam to handle cutting offsets.
