Most controls will take 4 decimals from Vector and not have any
problems with IJK. I get about 1/1000 arc errors on my Fanuc 5T
controller. It rounds the 4th decimal incorrectly(math done in ttl
level IC's and limited medium scale IC's, no cpu) and once in a great
while it errors out. Make sure that you are using geometry created
in Vector or at least trimmed with Vector general accuracy set
to .000040 inch (the default). that way there will be no little gaps
and arc errors. Also make sure that you Shift select, rather than
(never never never) box select. Sometime you may want to filter out
very small radius and very short arc span arcs to prevent looping at
the control. Many will filter this out, but no all.

Best cure, make sure that you are not trying to generate IJK code
with only 3 decimals.
