I've had a very small 7" x 7" cnc machine for about 5 years now but never had the time to really learn how to use it. Now I have time but cant get things to work. In my quest for answers to my current issues I've been seeing a lot of really nice larger projects that people have made using there machines. This makes me start to wonder if I'm barking up the wrong tree and if I really want to do any serious cnc work then what would I need to look at as far as a machine and controls to operate it with. My shop is still small but I could maybe get a 24" x 24" tabletop unit to fit nicely. Would anyone have any advice or recommendations of units to look at? Would it be possible to do (all in...unit, controller, software) under $2000.00?
