¶ E211 - R Nozzle T does not change during heating
¶ 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 left extruder assembly ( Figure - 2 ), make sure the heater has no short of circuit by measuring the 2 pins of heater, then measuring the resistance through the 2 pins as well (Figure - 3), the normal value should be around 8.5Ω@25°C. If there is short of circuit, or resistance value is too big or too small, please replace the nozzle heating cartridge. (Step of replacement)

(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 right 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.
