Re: EMC Continuous Contouring

John - Thanks, I agree a single 360° arc should be smooth, but I am
concerned that an arbitrary program not pause at any point. Andy

More info : A rectangle with filleted corners appears to go around
with no pauses, perhaps there is something wierd about starting an
arc after another arc, or 4 decimal places not enough for a smooth
transition. Andy
