I don't (think) the 2 rail sweeps are doable on V carve pro
No, but the moudling toolpath is very powerful. Alex Navarro has a tutorial on Youtube.

Vcarvers, a question,
Can your control accept a 3D contouring path from an outside cam system gcode (Fadal / Fanuc / Haas) anyone want to do a violin bridge?

I do not use clamps or tabs in my cnc work. Most of what I do on the CNC is relatively small objects. For milling one offs I have found that the 3m blue tape/superglue method works really well. I have used that method to make fixtures that were 35" long and the part did not move. I have never had anything move. That method of holdown is the most significant thing I have found in my cnc work.
As for fretboards, and neck headstock shaping (and inlay) I use small vacuum fixtures that are set at locations I can duplicate at any time. These fixtures are located with dowels and tape/superglue in place. That way I can take the part off the cnc and do whatever work I want and then later put it back on the cnc for inlays, etc.

I know VCarve and Aspire don't do that.

I just got MasterCAM. I'll have to research if it can handle that.

Another interesting video about CNC and inlays on curved guitar fret boards.

Cool, to send mcam 3D to the machine here is a sample file to play back.

I "clamp" what little I've done to the spoil board, using blue painters tape and ca glue. I tape up the spoil board top, then tape the bottom of the work piece. I put a few spots of ca glue on the taped bottom of the work piece, then glue it to the taped board. I've never had anything come loose while using the cnc, but the tape removes cleanly and easily from both pieces when I'm done.

I wouldn't know how this would work for a large piece, like a neck, but it definitely works well for the smaller stuff.

Is there any interest in a 2 day course on "CNC and Acoustic Guitarmaking"? I remember just getting a machine was overwhelming and it took literally years to develop the techniques, jigs, and vacuum fixtures to make the CNC worthwhile.
Would a course be helpful and would there be any interest? PM me if anyone has an interest!
Thanks.

Good thought, there is a dearth of CNC knowledge out there.
This is a very complex and varied subject.
I would start with drafting / CAD prerequisite and then to CNC.
