I am getting a small lip when i use the cutout tool path. Picture attached. also the file.

Thanks for the file and photo.
Most of the toolpaths are disabled, so I’m not quite sure which ones were used on that cut. Can you update the file to enable them, or tell us which toolpaths were used?
Another possibility is that the wrong cutter was used on the outside of the lip, so it didn’t cut far enough to clear that extra bit of material. This would likely make the inner lip too wide as well. So, if that’s the wrong dimension, the wrong tool was inserted into the machine during runtime.

sent the wrong file…will resend tomorrow.
Here is the file…BTW…I am using the IDC Beast 1/4" bit.

Your preview shows an almost exact cut around the lip, depending on the material being cut with the tool just barely reaching it.
with two Contour toolpaths interacting with two different pieces of geometry:
When a proxy of the tool is drawn against the larger/outer geometry:
one can see that it just lines up with the outer edge.
If you instead further offset this geometry:
and use that for the outer contour, then the tool will comfortably overlap the edge:
Or, just cut add offset geometry and as a pocket:
n
and then start the outer Cutout toolpath at the bottom of that pocket (you’d need to do the same thing for the other part)

the tool paths for the top and bottom of the box are the same and using the cutout toolpath starting at .0. The cutout on the left leaves no lip…only the one on the right…and not all the way around. I have the wood held down tight, so I did not notice any movement during the cut.
Just FYI…I have used this design many times in the past with no issue…only recently has this started to happen.
The two toolpaths are associated with different geometry:
Since as you noted, the left toolpath needs to start at the top, then you would need two separate toolpaths for the Cutout operations if you did as suggest above, which would preclude the possibility of any uncut material being left.

Yes, but the other edge of the side with the problem is the afore-mentioned toolpaths.
One more time…
This is the first toolpath cut…15" deep with 1/4" bit and outside/right. This is titled Lip1. The Lip2 toolpath is same depth but offset .04"…just enough to fit inside the pocket of the box bottom.
Then the cutout toolpath. I assume the cutout toolpath uses the outside/right. And I assumed it should flush align with the outside of the Lip1 cut.
This is where i get the small left over…yes, i know i can set up another toolpath to eliminate the leftover, but i would have thought that would not be necessary. Maybe bad assumption.
