Clearly, I've not been reading in the right place. That 7% is new info
for me. I assume that the 7% is a worst case but I have no idea how
someone came up with that figure. I that magnitude of error is common it
is a serious fault but I don't think I've ever seen real errors but
then how many of us have good enough instrumentation to check that. So
much of what I do are perimeters of features that don't have to exactly
match anything else so obviously we get away with it. In reality I
suppose that if you need it nice and round you interp to close and then
use a boring head but that does not solve some conditions. Can't win
them all.

Hi,
It would appear that the 'easy' way to compare the two methods would be
to use sim or usrspace. That would get it plotted but I doubt the
differences, unless gross, would be easily detectable on a plot.
Thde docs state that a 7% difference was seen, but with some brief
experimentation I can't see it:
F1000
G0 X0 Y0
G2 X10 Y0.1 R5.00025
G0 X0 Y0
G2 X10 Y0.1 I5.0 J0.05
M2
