A print I had left going overnight went spaghetti and got gunk all over the nozzle, as I was cleaning off the nozzle the power suddenly shut off and I haven’t been able to get it back on since. The power switch glows when I turn it on and I can hear the clicking of the power supply turning on and off but nothing else happens. Anyone know what’s wrong and how to fix it?
Yes, you blew a fuse. NEVER clean your nozzle with the power on. At least with nothing conductive. Heat it up, turn it off then clean it. You’ll need this as the replacement. https://www.lulzbot.com/store/parts/5-amp-nano-polyfuse-x3.
This post fits your scenario and has a little bit information about the fuses and their functions.
