Hello Archie
As a guitar maker myself and a fairly hopeless cnc person (brought up before calculators were invented) I got a makko machine years ago and it sat in my workshop for years as a shelf. I discovered uccnc software eventualy which made the machine actually workable although not great. I think Jazz should be able to sort you out with a good machine. I did end up buying plans and videos from https://cncguitar.com/cnc-guitar/fus...rchtop-guitar/ and found them easy to use with ready files and tutorials (I'm not affiliated with the company) If you have some pre made files it makes things faster and the videos are good for learning. May I mention that you should try and make a Jazz guitar by hand first to learn the realities of putting an instrument together. When it comes to making guitars cnc will save you a lot of time for many stages but also slow you down (Initially ) in other stages. Producing multiple parts for example where the main effort goes into the 3d designing in the software which after it's done than it's just a matter of setting up and routing. CNC is a bit like learning another language, hard at first and then it clicks and becomes much easier. Good luck and have fun and always make test cuts in mdf or insulation board to save mucking up and expensive spruce top or maple back.
Cheers
