Been running for months now in a heated chamber! These cameras should be easy to adapt to most printers. It was only supposed to be a temporary addition to fit for troubleshooting, but it's holding up to almost constant use really well!
What do you use it with? A pi?
Yeah, it runs Klipper so the Pi is doing most of the crunching and also acts as a webserver. A long USB cable to your computer or phone also gets the job done. It's mostly to help with tuning and diagnosis, because you can actually see what's happening rather than just seeing the effects of what happened, and is meant to be removed after use, but I've still been daily driving it!
