Thank you for letting me join the group.
I have an Anet A6 and Ender 3 3D printers operated by separate Pi 3B+ and wanted to see printing progress without going up and down my basement stairs constantly. I started reading up and found lots of solution but being a retired cheap steak it needed to be cheap. On ebay I found these web cam's for $3.77 each shipped so I ordered two of them. Notice it says no drivers required...
They arrived yesterday and I couldn't wait to try them out. After booting both pi's automatically saw them when and when I choose the control tab they they were!!!. One was slightly out if focus but I found turning the lens was easy. Next is finding and printing mounts for them.
My pi's are loaded slightly different, after setting up the image I could not get wifi to work so I connected KB, monitor and mouse to the pi and there were instructions on loading a desktop. That made setting up Wifi easy and that might be possibly be why the cameras were no brainers to set up.
Sorry for the long first post.
