Vcarve, drobbox, mach3, and virus software, windows updates are turned off. I typically do my design and gcode generation on the shop computer and save them to dropbox, they show up within a minute or so on the cnc computer. I really don't need Vcarve on the cnc computer, had just loaded it when I was first setting it up. I'm not sure I really need the virus software since it's all scanned at my shop computer also. I don't get on the internet on the cnc pc either.
