The original issue was with an IP camera I bought. Chinese off-brand. Could not get the web-admin to work. I later found out it was incompatible with Chrome. But, it also required a plugin from an unknown Chinese company to view it in a browser. The guy who sold it to me on eBay said he used other options which I might try.
Meanwhile I set up a Raspberry pi and a webcam.
My printer (BOSSDelta300) has a lot of sensors. If anything I'd like a comb brush that rises with the head.
