Using the guide I created earlier, I've now got the second webcam running on my printer. I needed a quick-and-dirty method of monitoring my filament feed for this print job since that roll's gone a little brittle and I need to keep an eye on it.
I decided to just drop the external webcam feed as a background graphic for the temperature graph and I'm using Themeify of course to do that.
It's actually getting its 5V power from the mining rig's extra USB connections on the back and it's now strung from the filament holder.
