First time trying my C beam XL, using Blackbox. Control is loaded on my PC when I open "Hello World" in CAM software I get a message in the lower right that says "Connecting to a machine, requires that you have the OpenBuilds CONTROL installed. If you have not installed it yet, you can download it above, or if you have the latest version installed already, please start it. If you still see this message, we are experiencing a problem detecting your driver" I have reinstalled and same thing happens. I am able to home and jog the machine using Control. Is this a PC problem?
