Attached are two files (dxf and tap).  During run progam i get an error on line N70.  It looks like the cutter is getting too close to the next edge.  error says "Tool radius no less than arc radius with comp on line numbe(message get cut off).  Have a look.

Lots of progress on the last update. Good work

This is the limitation of cutter comp I am working on offseting the path in Lcam to help with this probelm

Any radius on an inside corner must be at least the tool diameter or larger. The tool can't follow the path if the radius is smaller than the tool You can turn off advanced comp, but you'll get gouging in the corners then.
