Hi everyone, I am very new to cnc and have only done a limited amount of manual mill/lathe work so please be patient as some of my questions may seem pretty ignorant.
How do the older cncs work? For example, the 1900 dollar older Bridgeports you see on ebay. Do you write the program onto a disk and enter it in the machine or just type the movements right into the control on the machine? Basically most of what I will be working on will be 1/4" to 1/2" depth cuts in aluminum. Mostly for hobby use because I enjoy the hell out of milling and lathe work. Not looking to sink alot of cash in a machine right away. Maybe something with around a 9x32 table? Maybe a round coloumn machine? Thanks for the help.
