Fusion 360 / Shapeoko 3 Project Help

So I designed a small base for a PCB I designed but I’m having some issues with it milling properly. I was wondering if someone could give me some guidance on what clearing methods you’d recommend. Right now the issue is its not milling the standoff heights properly, they are coming out flush with the walls.

The height of the inside wall is 3.81mm and the height of the standoffs is 2.54mm. This doesn’t seem like it should be a problem at all.

Seems simple enough, and quite similar to the lid for the tool box tutorial I worked up: http://www.shapeoko.com/wiki/index.php/Carbide_Create_Photo_Tracing — do it in Carbide Create instead?

Ok, I edited my post because I realized what you sent me was how to trace - DUH! I’ll give it a shot.

This seems simple enough no tracing needed — just enter the dimensions for the various elements of geometry and do the selections properly when generating CAM paths, get a good preview, then do a test cut in a piece of scrap first.

You could use a 3D pocket operation if you want to do this in one operation (set the inter boundaries as the limit).

For more control (and a more efficient tool path) you could use two 2d operations. One operation to pocket down to the top of the standoffs (selecting just the pocket profile) and one operation to clear out the rest of the area (selecting the pocket profile and the standoff borders). Use the bottom slelction to limit the 2d pocket depth.
