Take the black plastic connector on the two white wires emerging from the back of the
new thermal core and plug it into the black connector coming out of the active cooling
fan assembly.
19. Push the heater wire connector and the slack on the heater wires into the cavity
formed by the active cooling fan mount.
Make sure the fan wire connector from the front extruder fan is also pushed into this
space.
20. Add the fan assembly.
With the fan assembly fully assembled, slide the
ends of the fan assembly bolts into the two
holes at the front of the bar mount. Slide the fan
assembly all the way on, so that a small portion
of each bolt emerges on the other side of the bar
mount.
21. Add the motor assembly.
Slide the motor assembly under the extruder
cap. The black plastic drive block should be at
the side closest to the heat sink and the two
holes at the lower corners of the motor should
line up with the ends of the bolts from the fan
assembly. Use the 2.5 mm hex wrench to tighten the fan assembly bolts into the
motor.
The heater wires may get in the way when you try to secure the motor. Push them as
far as you can to the side.
22. Plug in the motor wire.
Add the white plastic cable connector from the extruder cable to the top of the
extruder motor.
23. Return the wire wrapping to the extruder cable.
Wrap the black wire wrapping around the entire length of the bundle of extruder wires.
24. Zip-tie the wrapped extruder cable to the extruder.
Position the zip tie as close as possible to the extruder cap and tie it as tightly as you
can.
