I would like to start with the fact that I am a very new and inexperienced 3d printer operator. just few weeks of experience.
I started a print which was going to take a fair amount of time and I had to leave it unattended overnight. When I woke up the first thing was to check the printer from the control tab in octoprint.
The job appeared to be finished but through the camera I can see that the nozzle was still on top of the print and the scariest thing was that the heated bed was on 60° and the nozzle was also on 195°. It was just sitting there no movements and not extruding just heating what was left of the filament.
In the Temperature tab of octoprint the target temperature was off but the actual temperature was 195° and 60° as I mentioned
In the connection box I could see that the printer was disconnected
I hit the emergency stop button to cancel the job
After that I started another print and on purpose disconnected the USB cable and the printer did the same thing just stopped in place with heating still on which is a huge fire hazard.
This leads me to believe that there was a communication error and the print did not complete to the end even though it looks finished.
Does anyone have suggestions how can I setup unattended prints without worrying that I will burn the place down?
