Hi everyone,
This is my first post on here so appologies if I have put this in the wrong place.

I have been wanting to get a CNC for a few years but have never had the money. I have a budget of around £500 and cant decide how to use it. My options are either a pre built machine / kit like a 3040 router, build a machine from scratch, or convert my Warco WM16 mill to CNC.

I am leaning towards converting my mill as I want to be able to do some machining in aluminium, brass, and maybe steel but I dont know how much this would cost and I would like to still be able to use it like a manual machine afterwards (maybe some kind of hand wheel like on big boy machines).

Anyone with a 3040 type machine, how capable are they and how is the buing experience?

I have a lot of experience with 3D printers and CAD software (Fusion 360) but none with any machining specific software or machines other than watching videos on youtube.

Thanks
