I've just started getting a handle on Octoprint. My printer self destructed today, when I rebuild it I'm going to need a way to monitor it (video) and shut it down with my phone from anywhere. ...I'm going to have to google CNCjs, that's a new one for me. I turned the WiFi off on my CNC machine almost from day one. I figured that it was a bad idea to have a machine like that remotely controllable, even on a secure network.
