Mill V-Carve Greyed Out - Unavailable

I am currently using Rhino 7 with BobCAM for Rhino V2. I am trying to follow the instructions in one of the BobCAM for Rhino tutorials. I have created the text, but when I attempt to engrave the text, Mill V-Carve is greyed out and not available. All of the other operations are available except probing. What is needed to make Mill V-Carve available?

Thanks

Hello Cabinetmaker,
Sorry for delay. V-Carve is only available in BobArt.

Thanks.

Money…tho you don’t really need v-carve to engrave…i just use 2d engraving…
