At least I have only been burning through Home Depot stock. This has not been as successful as I would like to say the least. to date I have tried a few non integrated CAM packages that require me to create multiple non connected files and restart each job by reestablishing Zero at a new point on the stock. I was woundering if there was a way in VisualCam to mill the different dimensions of the stock from a single or linked set of processes. Since I am already old and would like to make more than a couple of neck before my demise. however that would either waist a good deal of lumber or spend a good deal of time milling the air above the thinner stock portions. It seems to be easy enough to mill the part from a single sized piece of rectangle stock that is assumed by the software. since all of my drawing are in Solidworks I certainly assume it would be better to have something integrated. I have been sampling CAM software with the hope that I could mill the stock from a semi shaped piece of stock ( shown below ). I wouldn't learn CAD here, but I do really want a community-developed Linux desktop CAD program.After making guitars completely by hand for quite some time and and not being as young as I once was I find that the filing process is talking its toll on the old shoulders so I purchased an X-Carve to hopefully help in that arena. Needs a lot of work (e.g., good part assembly capabilities) and I find it rather clunky.

FreeCAD (Windows/Mac/Linux) (GPL) is the open source Fusion/SolidWorks equivalent option. Seems to have a bunch of plugins, but actual CAD capability is run-of-the-mill. OnShape (clound-based) ($$ but IIRC has hard-to-find public/free tier) is notable for working in a web browser (good for Linux users). IMO, slightly better (smoother/faster/more robust) for modelling medium-to-large things than Fusion 360. SolidWorks (Windows) ($$) is industry-standard. Would definitely not attempt to use to design an assembly of multiple parts. Good for generating triangulated files of complex-but-formulaic objects (e.g., gears/screws), but is ~10x slower to use than Fusion for most anything else. OpenSCAD (Windows/Mac/Linux) (GPL) is text-based, which is nifty but really limiting. I'll concur with all the other recommendations I see here. Fusion 360 (Windows/Mac) (free for hobbyists) can do complex many-component robots or simple geometric shapes and has facilities for rendering and simulation. A (non-exhaustive) list of hobbyist-accessible engineering CAD programs I can recommend:
