Webcam Video Into The Cloud + Remote Emergency Stop

Just wondering if there’s any decent solution to view the CNC working remotely. Similar to how 3D printers have a webcam that pushes to the cloud and you can watch it on your mobile phone.

Also it won’t really help to watch the mayhem unfold if I can’t stop it… so how do I stop the machine remotely? I’m thinking worst case and probably the easiest way is to have a special outlet connected to the internet that depowers it. Any suggestions?

The absolute best possible suggestion is “Don’t do it”.

Seriously, it’s a Bad Idea ™. If something goes wrong, the time from “Looks like something is wrong”, to “Fire! Fire! Fire!” is literally measured in seconds in a worst case scenario.

In this video (shot at 4X speed), the time from stock moving to fire is 6 seconds, equivalent to 24 seconds real time.

I have a spare wifi camera that I used to put at my front door, now I set it next to my CNC outside the acrylic box I made for the CNC. For a long job I typically start the job, watch it for 5 to 10 mins to make sure nothing bad would likely happen, then go back to my desk and watch the camera, so as to avoid the noise and dust - the acrylic box is not perfect and dust do come out.

Like @mhotchin mentioned I don’t think having a remote stop button can save the project if something really bad happens, but I like the idea of having a camera so that I can get away from the noise and dust during a long job.

I work from home a few days a week. On those days I like to run my machine. I have an Arlo Camera Set up so I can watch my project from my home office. This is also cool because I can record the machining and send it to customers if they watch the recording.

I would never leave my machine running without being within earshot of the machine. I have had workholding fail and lots of smoke, but luckily I was able to get to the machine before it went up in smoke.

If you really want to do this, check out Teamviewer.
