Under "Arc breaks", if you put check marks in the "Allow 360 degree arcs" boxes, you will come up with something like this:

A little off topic here, but why is there even an option to turn off "Allow 360 degree arcs"?

[Guest CNC Apps Guy 1]

Not off topic at all IMHO...

 

... because some controls only take "R" (IIRC does not support full arcs) and not "I","J", and/or "K" (which does support full arcs).

 

So you have the option to use what your machine can handle. Granted, the machines that do not support full arcs are most likely older than some of our junior(in age) forum members, they are out there still and they pose unique challenges for the people that program them.
