I have a JCUT CNC Router that I use for carving wood helmets. Deep Z and compound curves. Its a pretty small business operation. Not my main source of income by any means

I used to have Rhino Cam 1.0 and used Rhino Cad 3.0 to do design. This worked well enough (and I wouldn't know better because I have never used anything else.) My computer died and Rhino doesn't support 1.0 any longer so I now have no Cam Software.

Just because its what is familiar I am considering purchasing Rhino Cam again (whatever the current version is.) I know it will be expensive (to me) and I will need to upgrade the Cad in some way. I have been resisting doing this wondering if anyone had advice.

I don't want to spend lots of time learning a new CAM software but if there are good ones that are cheap and good training available via youtube or something like that I would love to hear.
