Cut Inner Shapes First option causing incomplete paths

[benjaminhk (Benjamin)]

I am trying to laser cut a fractal puzzle.
I am having an issue with what seems to be the “cut inner shapes first” option in the “optimization settings”.
When it is on the cut path seems to skip the end of some paths:

Turning it off seems to fix it:

Is there any reason why it is doing this or am I doing something wrong?
Any help would be greatly appreciated.

I think the “Cut inner shapes” first is a red herring. The actual root cause of the issue is the kerf offset that you have applied. Because you have mixed closed and open shapes the kerf offset may be causing unpredictable effects.
