Hey there, new here but I’ll weigh in on this one.
I 100% agree that if you can pick it up, it’s not going to cut what you want. At least not quickly, or pretty-like, or with large bits.
First question would be, have you ever used a manual milling machine? If not, I’d suggest going manual before CNC. CNC requires you to know feed rates, and requires a good bit of “feel” for the machine. Unlike 3d printers, its not just load up and go.
