While attending high school, I was lucky enough to have access to a desktop sized CNC milling machine which took a lot of labour out of machining and allowed me to focus more on detailed design. Since that time has passed, but I still have machining needs including parts for my electric car, enclosures, and various other projects, I justified the purchase and intent to build a CNC milling machine.
Here is an index of my ongoing quest to convert a relatively low cost milling machine to CNC control.
