Thanks again, I was concerned that I had failed to discover the obvious tool.

All the advice will be followed.

My next step was to investigate the uses of polylines.

In the CAM, the shape is always converted into a polyline to enable a closed loop GCode sequence to be produced.
The default join tolerance followed to date is 0.01 mm, which joins up the 0.001 mm errors (without removing them), and writes GCode following the errors.

I should note that LinuxCNC is not to blame here, it is my poor drawing.
This whole episode started when I began investigating cutter compensation on the fly in the mill.
If I instruct CamBam with the correct tool diameter, it will either highlight a problem, or generate a GCode file that is always acceptable to LinuxCNC.

Keep well,
John.
