This is a huge understatement. You also need large investments in consumable tooling plus metrology tools to do anything useful with metal. The entire operation is really loud, slow, dangerous and throws chips everywhere.
The whole point of the linked article is that CNC machining is a pretty awful fit for a hobbyist! It literally recommends finding alternatives with stuff that's easier to have in a home.
- throwaway4aday 4y agoI don't think it's that much of an understatement looking at the table top CNC machine that I got off Aliexpress and upgraded so that it could mill aluminum. Same stepper motors, same Arduino type board, moderately fancier bearings. The main things I had to do were just beef up the frame with some plate and replace the dinky spindle that came with it. I'm not making precision parts with it, just fun hobby things and artsy stuff.
