Process
1.1
From the underside of the (02) Printer Base, insert 2x M5x45
hex socket cap screws through the predrilled holes on the left
of the frame, so the thread is sticking out through the top face
of the aluminium profile
1.2
Identify each of the Z-axis vertical profiles to be used in this
step: (15) Z-axis vertical profile left (2040) and (16) Z-axis
vertical profile right (2040). While they may look the same there
are subtle differences:
The (15) left vertical profile can be Identified as having two
threaded holes, one next to the other, positioned close to the
end. The end with these two holes is the base of the upright and
will be attached to the (02) Printer base;
The (16) right vertical profile features two threaded holes, one
on-top of the other. Positioning of these screw holes are not
symmetrical, with the hole closest to the end of the profile
being the bottom hole. This end, with the screw hole closest to
the end, is the base of the upright and will be attached to the
(02) Printer base.

Creality Ender 3 Pro Assembly Instructions V1.0 10 www.rb42.blog
1.3
Position (15) Z-axis profile left on the left-hand side of the (02)
Printer Base, directly above the two M5x45 cap screws (from
step 1.1) protruding through the base. Using an M4 hex key
(Allen key), proceed to screw the M5 cap screws into the base
of the Z-axis upright and tighten until upright held firmly in
position.
1.4
Repeat the process for the opposite side and (16) Z-axis profile
right. The process will remain the same albeit now on the right-
hand side of the base. Orient the upright so the channel with
the holes is closest to the printer bed

1.5
Confirm each of the Z-axis uprights are squared to the base by
using a Square (e.g. machinist square, set square, rafters square
etc.) to ensure an angle of 90°. If not exactly square, untighten
the screws and attempt to reseat the upright. If still not square
after this, additional frame bracing or gussets may be required.

Process
2.1
Set the power supply to the required mains voltage. The
voltage is altered by toggling the red switch on the back of
the power supply from either reading 230v for 230v 50hz
mains supply or 115v for 115v 60hz mains supply. Ensure
voltage is set correctly as incorrectly selected voltage will
cause damage to the printer and may cause further electrical
hazards.

2.2
Mount the (03) power supply to the reverse side of (16) Z-
axis vertical profile right (from step 1.4), the power supply is
held in place with 2x M4x20 hex socket cap screw which are
inserted from the front face of the Z axis profile using a M3
hex key (Allen key).
2.3
Attach the (01) LCD display to the front face of (02) printer
base on the right-hand side with 2x M5x8 hex socket button
head screws using an M3 hex key (Allen key) to screw
securely in place.

Step 3 - Z axis limit switch
Tools for this
step
M3 Hex Key (Allen Key)
Parts for this
step
1x (09) Z axis limit switch assembly
Process
3.1
(09) Z axis limit switch assembly is installed on the left-hand
side of the frame, at the perpendicular junction where the
vertical (15) Z-axis vertical profile (left) and the horizontal
(02) printer base meet.
3.2
Insert the T-slot nuts of the (09) Z axis limit switch assembly
into the channel on the side of the Z-axis vertical profile by
rotating the nuts so that they are in the same orientation as
the channel on the profile so that they are placed into the
channel without obstruction.
3.3
Position the (09) Z axis limit switch assembly so that the
positioning tab is resting on top of (02) printer base
horizontal profile.

Creality Ender 3 Pro Assembly Instructions V1.0 15 www.rb42.blog
3.4
Once in the channel, using an M3 hex key (Allen key) rotate
the orientation of the T-slot nuts by 90 degrees, making
them perpendicular to the channel of the vertical profile.
Continue to tighten the hex socket cap screws so the limit
switch is firmly held in place. Confirm both the T-slot nuts
are remaining at 90 degrees to the vertical Z axis profiles
once the screws have been fully tightened.
Step 4 - Z axis lead screw
Tools for this

Fixings
2x M4x18P hex socket countersunk screw
Consumables
Loctite 222
Process
4.1
On the reverse face of the (15) Z-axis vertical profile (left),
position the (08) Z-axis motor assembly on the (02) printer
base with the stepper motor resting on the top surface of
the aluminium extrusion and shaft pointing directly
upwards.

Creality Ender 3 Pro Assembly Instructions V1.0 16 www.rb42.blog
4.2
Secure the stepper motor into place with the 2x M4x18P hex
socket countersunk screws and tightened into place using
the M2.5 hex key (Allen key). These screws are feed through
two holes on either side of the plastic mounting block
attached to the top of the stepper motor and screwed into
the matching threaded holes in the (15) Z-axis vertical profile
(left).
4.3
Insert the (17) Z-axis lead screw into the Z-axis shaft coupling
on top of the (08) Z-axis stepper motor.
4.4
Slightly torque the grub screws using an M2.5 hex key (Allen
key) enough so the lead screw is held in place. At this point
in the assembly process do not tighten too much as we will
need to set the final position of this screw in a later step
(step 9.3).

Step 5 - X-axis and Extruder (XE) stepper motor assembly
Tools for this
step

Kit Open Ended Wrench
Parts for this
step
1x (06) XE stepper motor kit
1x (18) X-axis profile (2020)
Fixings
2x M4x16 hex socket button head screw w/ captive
washer
1x 1.75mm Bowden Coupler fitting
Consumables
Loctite 222
Process
5.1
Attach the 1.75mm Bowden Coupler fitting to the (06) XE
stepper motor kit by screwing into the threaded hole on the
extruder housing attached to the top of the extruder stepper
motor. Tighten the coupler into place using the open-ended
wrench from the tool kit supplied with the printer.

Creality Ender 3 Pro Assembly Instructions V1.0 18 www.rb42.blog
5.2
Using an M2.5 Hex Key (Allen Key), fix the (06) XE stepper
motor kit on to the reverse side of the (18) X-axis profile using
the 2x M4x16 hex socket button head screws. Make sure the
XE motor kit is positioned correctly on the left-hand side (right
on the reverse) of the (18) X-axis profile, using the 2 predrilled
and threaded mounting holes.

Step 6 - X-axis Synchronous Belt
Parts for this
step
1x (14) Synchronous Belt (77cm)
Process
6.1
Feed the (14) Synchronous Belt (77cm) under the plastic cover
and around the X-axis pulley (GT2, 20 teeth). The easiest way
to wrap the belt around the pulley is to feed the belt through
the cover, going in one side and out the other, then bending
the belt around and feeding back through the cover once
again.

Creality Ender 3 Pro Assembly Instructions V1.0 20 www.rb42.blog
6.2
Loosely wrap the (14) Synchronous Belt (77cm) around the
opposite end of the (18) X-axis profile. At this point the build
there is no pulley for the belt to go on, it will be installed in
step 8.
6.3
Approximately position the (14) Synchronous Belt so that the
end tabs are in the centre of the X-axis profile. The belt should
roughly be in line with the centre channel of the X-axis profile.
