Extra Circles

[Syd]

On a recent project I've noticed these strange extra circles and off-centered circles popping up in my g-code. They are always connected to another circle that WAS in the original code. That original circle is also offset from it's original g-code. I've looked at the code side by side and have found the numbers to be off.

Anyone seen this before? Am I doing something incorrectly?

You are seeing numerical noise caused by fragments of track data which are of zero length.

As sucjh they can be interpreted as arcs of very tiny radius.

I have had some bad experiences with these events with professional CAM software.
