To really understand what is going on here we would need the line before
n61 so that we know where the tool is supposed to be when this command is
issued. A bit of math and geometry would easily tell the source of the
problem.

Good thinking. I believe that this test in the stock release is set to
five sig digits.

There may be one additional problem. If Gene is trying to command a full
circle -- it is a tiny one -- it is possible that he is running into the
problem with some releases of the BDI ( >2.10 at least) and the EMC. For
full circles, there was a problem with it and full circles. The way to
overcome the problem with vector is to split your circles in half and
then ask it to generate the code.

It seems more likely with the tiny I and J that this is some kind of
contouring and just needs more significance to the computations in Vector.
