The the g-code programs posted above are these same carvings.
I do not see it in the preview, mostly because the W axis is not realy shown in the preview.
This machine configuration is a servo set up, and the problem might be magnified by a tuning issue. But I kind of doubt it since it doesn't show up with the old planner.
In the above g-code 130207LWZ.ngc the first errors start to be seen around line #13-15 and #17-19. That is the first tick carved on the clock face. The problem is visible on all of the ticks arround the clock. With the same mistake on the same corners of each one. This first tick begins the carving at the top left corner and continues clockwise around the shape. the 2nd and 4th corners carved are the ones where the mistake is seen.
Sraingly enough the very last thing carved in the file is the tick right next to the very first one. This one starts at the corner farthest left, then continues clockwise. So that the 2nd corner carved is the one that was carved 1st on the very first tick. On this last tick the errors are seen on the same corners as the first one, but are the corners that are carved 1st, 3rd (and last it finishes where it started) are where the error is seen.
