You will be mounting the blower fan assembly on the extruder later in the following steps.

Make sure the motor cable passed behind the bulge and under the cable canal over the extruder fan on the previous step.

Hold the hotend thermistor and heater cartridge cables as seen in the picture.

Add the 5015 Blower Fan cable to the harness.

Pass the Inductive Sensor cable through the canal at the back of the extruder body. Ensure to leave some space on the sensor cable to be able to adjust the height of it later.

Pass the stepper motor and heatbreak fan cables through the canal.

Pass a zip tie behind the cable harness.

Zip it and cut the excessive part.

Insert four M3 x 22 mm Screws from the backside of the X carriage and while holding the cable harness, align the bottom two screws with the holes on the extruder body and screw those two bottom screws first. Ensure that the cables are aligned with the vertical harness gap.

Now tighten the upper screws. The screw distances are precise, depending on your printer the plastic part may have less tolerance. Press and squeeze with your hand from the front if necessary while tightening.

Connect the X-Axis Endstop Sensor and add its cable to the harness.

Insert the Zaribo Filament Sensor connector and add its cable to the harness. If there is a rib behind the connector, feel free to trim it with a cutter. Some connectors might have a small rib at the back.

Collect the cables and prepare for the sleve.
