QT2DD Making massive cuts when machining internal arcs.

I produced the attached drawing using QT2DD (I zipped it because the forums won't accept .lcmfiles)

I then used the CAM Wizard to generate GCode in an .fnl file which is also attatched.

When I simulate running the code using QT2DD the internal turning tool makes a massive cut which would undoubtedly stall or damage a real machine.

The machine tooling and machine materials setting check out OK.
