I tried to print a thin model for the entire area. Plastic PLA, the temperature of the first layer is 220, the second is 215. When switching to the second layer and turning on the fan, the nozzle temperature drops below 200 degrees. After a while, the temperature rises, but Marlin issues an accident: "THERMAL RUNAWAY: E1" "PRINTER HALTED" "Please Reset". I flashed back the factory firmware. The same thing happens on it, only the printer does not issue an accident.
