Design edge not following cutpath

[i_r_machinist]

I have a new trainee and I think he changed a parameter or something because my cutter does not follow the path now.
any ideas?
thanks

Probably added one single dot outside the part and the cutter is going to that dot and then coming back.

Yep, a hard to see almost invisible line remanent with maybe an oversize kerf setting causing the cut path to wander where it thinks it needs to be.

If you want to upload that pcm file myself or someone else here could take a look at it....

Yup, Kerf settings! All better now.
thanks
