Toolpath Assistance

Evening Folks, running into an issue with a pocket toolpath not excluding selected vectors. This probably is not the correct/best terminology, so hopefully the picture helps

There are 2 vectors directly to the left and right sides of the bomb. If I only select 1 of these vectors to exclude the rest of the excluded vectors work as needed. The pictures shows what happens when I add the 2nd vector along side the bomb as a vector for the tool path. The toolpaths no longer exclude the area around the scales or the middle fin of the bomb.

The advanced V carve I’m using to clean up the tighter areas is having no issues deciding where it needs to go. I’ve been using carbide for about 6 years now and have never run into this issue. I have additional photos but the forum is only allowing me to embed 1.

If it matters, design and testing is on a windows OS however this file will be transferred to a mac OS version of CC in the shop.

Upload your .c2d file. Screenshots are informative but useless for diagnosis.

If you can, create two new toolpaths, one with the one vector selected, the other with both selected. That way we can be perfectly sure we are re-creating the problem as you see it.

c2d Uploaded. I labled the vectors causing the problems 1 and 2, and created a second toolpath omitting both showing the desired outcome for the scale area.

On the problem toolpath you have the inner vector (dashed) selected,

Which is preventing an 1/8" tool from getting into that area

Yes, I know. I’m using a depth limited V carve to clean out the areas that are too tight for the 1/8 bit, however am aiming for a flat bottom pocket for on the larger clearance areas, which has worked on a number of other projects. I’m running an S3 XXL and don’t have a bit setter or any other accessories installed so I end up creating a separate save file for each tool and running them independently

The problem persists even I select a 1/16 end mill, and I’ve also tried adjusting the “Inner” vector to be: The middle tail fin, the bomb itself, either of the problem vectors, and the scales to no avail. Anytime both of the problem vectors are included the toolpath wants to pocket the entire upper area.

If I open your file in CC V815, the problem toolpath is doing what it should, with those vectors selected.

I’m still running 778. Let me update and see if it resolves the issue. Will report back momentarily.

Edit: That has indeed solved the problem. Thank you for your assistance.

Cool. It looks like you are pocketing up to the same vector you’re V-carving.
In theory, it will end up looking like this

You could offset the pocket to leave the tapered walls, but then sharp corner would look like…

Either way is imperfect. I use a modified offset when cutting PVC to avoid burrs/tags…
