For the following steps, please prepare:
Notice that you have received three different lengths of smooth rods. We recommend arranging them all side by side, for easier comparison of their sizes.
Smooth rod 8x370 mm (2x) the longest couple
Wipe off the preservative oil from the smooth rods with a paper towel or a piece of cloth.
LM8UU bearing (3x)
The bearings come pre-lubricated from our factory and do not require additional lubrication upon initial use.
Assembling the X-axis: Marking the bearings
Assembling the X-axis: Marking the bearings
Wipe grease from the outer surface of the bearing with a paper towel.
Position the bearing so that you can see two rows of balls. Like in the picture.
Make a mark with a permanent marker on the outer surface of the bearing, in the middle above two rows of balls.
Use the same procedure for the remaining two bearings.
We will use these markings in the upcoming chapters to achieve the desired bearing orientation.

Insert the smooth rods all the way into the X-end-idler.
Insert the rods very carefully. Do not tilt the rods too much.
Through the inspection hole check if the smooth rods are in touch with the screws inside the part.
Carefully and gently slide three bearings onto the smooth rods. One bearing on the upper rod and two bearings on the lower rod. See the picture. Orientation of the markings doesn't matter at this moment
In case you manage to push out balls from the bearings, please count them. One or two balls are ok, if there are more of them, please consider ordering new bearings.

Insert two M3n nuts to the X-carriage-back.
Use the screw pulling technique.
From the opposite side, insert the M3x10 screw into the X-carriage-back. The screw must protrude from the "front" side of the part.
Attach the hex spacer on the M3x10 screw and tighten the screw. Note the cutout of the same shape as the spacer. It must fit perfectly and must not rotate.

CAUTION: Make sure you have the parts oriented correctly:
X-end-idler on the left.
X-end-motor on the right.
Two bearings on the "lower" smooth rod (closer to you).
Attach the X-carriage on both bearings on the lower rod. See the orientation of the X-carriage-motor on the picture.
Slide both lower bearings all the way into the pockets in the X-carriage and align them with the outer surface of the X-carriage.
Rotate both bearings so that the marking is facing you (down). Leave the upper bearing out of the X-carriage for now.
Cover the bearings with the X-carriage-clip and secure it by four M3x10 screws. Notice the orientation of the part. Do not fully tighten the screws at the moment.

For the following steps, please prepare:
X motor (1x)
Ensure you are using the correct motor, there is a label on the bottom of the casing. The reason is, each motor has different cable length.
GT2-16 pulley (1x)
M3x18 screw (3x)
M3x10 screw (1x)

Insert the M3x10 screw into the X-end-motor. Line up it with the edge of the plastic protrusion. Do not tighten the screw, there is no thread inside, just insert it freely.
Place the X-end-motor on the X motor. Secure it by three M3x18 screws. Tighten the screws just slightly. We will adjust them later on.
Note the correct X motor orientation. The cable must be facing you.
Make sure that the "tension" screw on the X motor side does not fall out during handling.
Position the motor so that the screws are at the inner end of the oval holes.

There is a flat part on the motor shaft. Rotate the motor shaft with the flat part facing through the opening in the X-end-motor.
Slide the Pulley on, note the CORRECT orientation. Compare it with the second picture!
Place any of the Allen keys on the top surface, like in the picture and align the pulley with the Allen key.
One of the grub screws must be facing directly against the flat part of the shaft. Tighten the grub screw.
Rotate the pulley and tighten the second grub screw.

Guide the X belt around the Idler pulley.
Insert the "clamped" pulley with the belt inside the X-end-idler.
Align the hole in the pulley with the left hole in the plastic part.
After aligning the pulley, push the pin through the plastic part and the pulley. Push the pin all the way in using the Allen key.
Do not apply excessive force when pushing the pin, as this could cause the pin to push through the plastic part, resulting in its breakage.
Pull lightly on the belt to secure the position of the pulley. You will see the pin in the hole slide inside the part. Once the pulley is secured, the pin is not visible at all.

Insert the "upper" end of the belt into the groove in the X-carriage. Push it all the way in using the Allen key.
Push the "lower" end of the belt through the belt channel in the X-carriage.
Guide the belt through the X-end-motor around the pulley and back to the X-carriage.

Guide the X belt to the X-carriage and push it to the groove in the plastic part as far as possible. Push it all the way in using the Allen key.
The belt must not be too loose (sagging). We will adjust its tension later.
Place the upper bearing into the recess in the X-carriage. The marking must be facing you, like in the picture.

Move with the X-carriage side to side several times to check that the movement is smooth.
After you ensure that the movement is smooth, fully tighten the screws on the X-carriage-clip in this order:
Upper left screw
Lower right screw
Upper right screw
Lower left screw
Move the X-carriage several times to both sides and check the movement is still smooth.

Eat five gummy bears.
Did you know that the original gummy bears were inspired by the dancing bears of Europe, and Riegel named them "Gummibärchen," which means "little rubber bears" in German.
It's done!
