Before these steps, it is recommended to protect the heatbed!
Insert and tighten the two screws. Tighten carefully, you can crack the plastic frame of the fan, also ensure no cable is pinched.
Merge all cables leading from the hotend together and guide them up. Don't pull the cables, leave some slack around the fan.
Start by rotating the lead screw until the X-axis is all the way up.
Add the EXTRUDER motor cable to the bundle and use the textile sleeve to cover the cables all the way down to the electronics.
