You may be able to use SheetCAM and a Post that will generate the correct code for the Burny 3 controller. The transfer method is probably serial (RS232) and the memory on the controller is probably limited so you need DNC (sometimes called a "drip feeder"). If the Burny has full RS232 implemented it should be able to stop and start the feed but you need a Your challenge will be to get from the new PC to the controller with a method both are happy with. I don't know if you can draw in QuickCAM but SheetCAM is NOT a drawing program. It takes DXF files in and generates g-code files out.
