¶ E313 – Right nozzle heat speed is too slow
¶ Right heating cartridge, PCB on right extruder assembly, cable of right heating cartridge inside right umbilical track, mainboard or else could trigger this error.
¶ Steps:
(1) Turn off machine, unplug the main power cable. Unplug the cable on the top of right extruder, toggle the buckle of extruder and take it off.
(2) Use 2.0 mm hex screwdriver to remove the 4 screws fixing the black cover of right extruder. (Figure - 1)
(3) Unplug the black plug in interconnection board of right extruder assembly ( Figure - 2 ). Then, measuring the resistance through the 2 pins as well (Figure - 3), the normal value should be around 8.5Ω@25°C. If resistance value is bigger than 11Ω, please replace the nozzle heating cartridge.

(4) After confirming the right heating cartridge is fine, check the PCB on right extruder assembly. Swap it with the left one or replace it directly for diagnosis. (Step of replacing nozzle heating cartridge)
(5) Please refer to E307, confirm if the nozzle temp sensor of rightt extruder is fine, replace the sensor as needed.
(6) If the interconnection board & temp sensor work fine, please replace the main board. ( Step of replacement )
(7) If issue persist after replacing the main board, please check the cable of right extruder inside the umbilical track.
