I have had the same thing happen twice where my printer is about 7 hours into a print and it just stops. The printer stays on but the extruder cools down as well as the bed. I haven’t been there right as it stops so I’m not sure exactly what it’s doing. I am printing the longest print I have ever tried before (close to 3 days) and I’m wondering if that could be part of the problem or maybe it’s part of the gcode or something like that. I’m using a tevo tornado and cura 3.2.1. Any input as to why it did this TWICE would be great!!!
