At AMT you are supposed to stand over your CNC machine as it is doing a job and pay attention. Is it hanging up? Is it breaking itself or the bit? It is on fire? These are all important things to know. However sometimes a job takes…forever. When cutting PCBs the job can take over an hour because I have the bit move so very, very slowly. Faster and the bit shatters into tiny little pieces of carbide all over the room. Not good. I’ve noticed for awhile that inexpensive internet webcams are available, think of it as a BabyCam for non baby owners. Turns out this little $30 wonder does a great job. When setting up the PCB to be cut I can put the camera on it, configure it to talk to my phone over the AMT network and I can be upstairs working on say a soldering job of the last PCB while the next one is being made. Very handy.
I would recommend everyone who has long CNC jobs they need to keep an eye on but don’t always want to stand over the device to try out something like this.
