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!
I had one of these on my MK3 previously and the footage they record is incredibly mesmerizing to watch.
Never bothered adding one on my Voron, mostly because it’s always a pain to route the cable properly but I might just give it another try at some point
There’s a really nice nozzle cam available for Voron now. You have to print the front cover part again, but it has a housing for a 4K nozzle cam. Much more pricy, but incredible quality, invisible and a bit easier to connect.
