¶ Nozzle Set, Hot End, Heating Cartridge, T Sensor
Taking extruder assembly off to replace nozzle set, heating cartridge & T sensor is more convenient and comfortable. While, it’s fine to do replacement without taking the assembly off. Choose the one you prefer.
¶ Steps:
a. Turn machine off, unplug main power cable, and wait till nozzle temperature gets close to indoor temperature. Then remove the rear cover of extruder.
b. Unplug the cable connector (J2/J9) of heating cartridge (front hot end) on interconnection board (Figure 2.2-1). Remove the 2 screws with 2.5mm AllenKey that fixing the front hot end (Figure 2.2-2). Then the front hot end and nozzle set can be removed.
c. Turn over the hot end, loosen the 2 set screws (Figure 2.2-3) with 1.5mm AllenKey, and then the heating cartridge (Figure 2.2-4) in front hot end can be pulled out.
d. Similar way to take rear heating cartridge off. Loosen 2 set screws (Figure 2.2- 5) with 1.5mm Allen-Key. Then, pull rear heating cartridge out of the rear hot end.
e. Nozzle temperature sensor. Loosen the 2 set screws (Figure 2.2-6) a bit in rear hot end, and pull nozzle temperature sensor (Figure 2.2-7) out of rear hot end.
