What is the problem?
Hello, I set up octopi / print on a pi3B. It seemed happy. I connected to the Lulzbot workhorse @ 115200. I saw some text go back and forth. It looked connected and happy. I got called to the front of the office to deal with something. When I came back the shop was filled with smoke. The printer seems to be working but the extruder / body have a nice ash coating from the smoke that I need to clean. I realize getting Lulzbot support is difficult nowadays and I may be one of the few with a workhorse printer... What did I do wrong and how do I keep this from happening again?
