Hi. I have a machine I use only for CAM, controlling a CNC machine with Mach3. The recommendations are to not change or upgrade anything once you have a stable setup.
I would like to be able to transfer files from my main computer to my CAM computer, and perhaps access the internet from my CAM computer using my internet Ethernet.
However, I want to make sure that nothing else happens, no updates, no viruses, etc. Can anyone advise how to set this up?
Thanks,
Bryan

If you want internet access, it is difficult to GUARANTEE that nothing happens. The smart thing would be to give the computer local area access so that you could get to other computers on the local network but not provide a default gateway. That will prevent the CAM computer from getting outside the LAN. Even with LAN only access, a software firewall on the CAM computer would be a good recommendation to protect it from compromised computers on the LAN.
