¶ E210 - L Nozzle T does not change during heating
¶ Left heating cartridge, PCB on left extruder assembly, cable of left heating cartridge inside left 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 left 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 left 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 heater. (Step of replacement)
