Re: [CAD_CAM_EDM_DRO] Re: Bridgeport Conversion

It may be better to buy a used CNC mill and rip off the old computer
keeping the operator console, power supply, drives and motors factory
installed. Interface the PC to where the old control hooked up. Big
advantage is the CNC mills with obsolete controlls (BOSS) go for cheap.
Just make sure the mechanicals are still tight.
