If you're experiencing troubles with getting nut into the top hole, just follow these simple steps.
Screw M3 nut a bit on a long screw (M3x40 from 9.SPARE bag works in most cases).
Push the screw with the nut into the hole where it is supposed to be.
Grab the screw with pliers and gently hammer the nut in place using a wrench.

Place the M3 nuts (2 pcs) into the traps on the left side of the extruder body.
Slide the M3nS square nuts (4 pcs) into the traps on the right side of the extruder body.
Place the nuts as deep as possible.
Ensure you have placed all nuts (from both sides of the body).

Slide the extruder body on the nozzle as shown in the picture.
Push the nozzle all the way down and make sure that cables are on the side as shown in the picture.
Be careful with all extruder cables from now on.

Place the M3 nuts (2 pcs) into the traps of the extruder cover.
Top nut needs to be pushed all the way down! (the nut trap has 2 diameters, only last 3 mm have correct diameter for the nut trap).

Mind the correct orientation of cables leading from the extruder heater.
Using the 2.5mm Allen key tighten both screws to mount the extruder cover on the extruder body.
Make sure to use the proper length of screws when mounting the extruder cover. Check all nuts are in their places.
Tighten until the nozzle stops moving in the extruder, if there's still a gap between the cover and the body it's alright.
The M3x18 screw needs to reach just the first square nut. The second square nut is for a different screw used in another step.

Preparing the extruder motor
Press the pulley on the motor.
The screws must be facing directly against the pad (flat part) on the shaft.
If you're experiencing trouble, loose the grub screw a bit.
Note the correct orientation (the screw has to be closer to the motor).
Don't tighten the pulley at the moment, we have still time for that.

Using the 1.5mm Allen key tighten the pulley.
Make sure that the part with smaller diameter is perfectly aligned with the nozzle entrance.
Make sure the pulley can rotate freely.
Use a piece of 1,75 mm filament (from the spool) to align the pulley with the openings for the filament (see the picture).

Screw the extruder screws into the extruder body using the 2.5 mm allen key as shown in the picture.
Length of the springs should be circa 13 mm when tightened.
It is alright to tighten the screws with higher force, we need to induce pressure on the idler.

5015 print fan
M3x20 screws (2 pcs)
Screw the fan on to the extruder using the 2.5 mm Allen key as shown in the picture.
Do not tight fully at this moment, fan should just be secured in place.
Front print fan is in the box 2.3.4.5.SUP

M3x20 screw (1 pc)
Tighten the fan nozzle using the 2.5 mm Allen key. Gently tighten screws holding up the fan in place.
DON'T tighten the screws too hard, all parts are made of plastic and you can break them.
Double check that the fan can rotate freely.
P.I.N.D.A. probe preparation
P.I.N.D.A. probe preparation
Prepare the P.I.N.D.A. probe (autocalibration) by removing both of the nuts (if included in delivery)
P.I.N.D.A. probe is in the 2.3.4.5.SUP box.

Pass the P.I.N.D.A. probe through the mount.
Guide both cables through a cable clip on the extruder body as shown in the picture.
Exact position of the P.I.N.D.A. probe will be adjusted later (in Chapter 9, Preflight check), so there is no need to adjust or tighten fully at this point.
The best position for mounting at this point is to align the last thread of the probe with the end of the mount
Note the loop on the cable from the probe, it's necessary to apply it correctly!

Please tighten the screws in the order described below:
First, tighten the top screw. Don't tighten it fully!
Now tighten the left screw. This one you can tighten fully.
Tighten the right screw fully and then return to the top screw and tighten it as well.
After tightening all screws mentioned above tighten the last screw, which will be used for cable management.

Guide the cables as shown in the picture.
Make sure that the wires from the thermistor are going above the heater wires.
Running them below will cause issues later, don't do that!

Insert a ziptie (longer one in package) in the right side of the X-carriage so that cables from the extruder motor and the fan are below the ziptie and held in place.
Double check the orientation of the ziptie.
Once all cables are neatly arranged, finalize it by tightening the ziptie and cutting off the excessive piece.
Use pliers to cut off any excess ziptie.
Preparing the filament
Preparing the filament
Starting mid of February 2018, there will be only one 50cm NYLON filament included.
There are two NYLON filaments included in the kit with lengths 50 and 30 cm. Both have Ø 3 mm. For this step please use the longer one and DON'T CUT any of them!
Push it all the way down. If you experience difficulties when inserting the filament use pliers to make a sharp tip on the filament.
The filament is for the support of the whole harness. Don't cut it, it'll go all the way with the wires to the cover for electronics.
Note the correct orientation of nylon filament, it needs to point up as shown in the picture!
Nylon filament is pictured in orange colour, but in your kit can be the black version, which is the same, just different colour.
Spiral wrap ziptie

Wrap the spiral wrap (the largest and the longest one) around the cables and the nylon filament.
Start with cables from the upper part, after 1 turn add cables from the hot end.
Double check by moving the extruder fully to the left or right that spiral wrap does not interfere with the printer frame.
Use zip ties and tighten the wrapped cables and spiral wrap. Tight the spiral wrap to the cable stiffener.
Use one piece at the beginning of the spiral wrap.
Tighten zip ties carefully, too much pressure can damage cables inside! Don't tighten the zip tie over cables only!
Finalizing the extruder
Finalizing the extruder
Check for free movement of the X-carriage and inspect cables in the full left and right positions.
Once you are satisfied with organisation of the extruder cables finalize spiral wrap to the full length.
Separate the filament at the last whirl of the spiral wrap.
