Use M10n nuts (14 pcs) , M10w washers (12 pcs) and M10 threaded rods (2 pcs).
Screw the nuts on and place washers, Y-corners and PSU-Y-part on the threaded rod as shown in the picture.
Ensure initial 100mm (3.937inches) distance between a washer after counter-nut and the Y-axis corner. Use the photo as a reference.
The 2 nuts have to be tightened against each other (counter-nut).
Note that there is no gap between parts, they have to fit together.
For the initial position of Y-corners, you can temporarily mount the rods (see step 10, 11).

Screw the nuts and place washers and Y-motor part on threaded rod as shown in the picture.
Y-motor part should be somewhere in the middle of the threaded rod. The precise position doesn't matter at this time.
Ensure the correct orientation of the Y-motor part.

Insert Y-axis stage front and back into Y-axis side elements and lock it with washers and nuts like in the picture.
Ensure the correct placement. The Y-axis rear stage has to be closer to the double-nuts!
!!! Given dimensions are recommended, not absolute. Use them as a guidance for your assembly. Your final values can slightly differ.

Insert the Y-axis stage into the frame as close to Y-corners as possible.
Adjust and tighten the M8n nuts.
Rotate the Y-axis stage and repeat.
After adjusting, the Y-axis stage should cause minimum movement while inserted into the frame.
Tighten the M8n nuts gently or you'll risk damaging the 3D printed parts.
It is incredibly important that the axis is perfectly rectangular at this stage of construction, all rods need to be perfectly straight and level. If not, you'll have troubles calibrating later on!
The aluminium frame is used just to set the proper dimension, do not mount it to the Y-axis, we will do that later.
Insert the Y-axis stage into the frame as close to Y-corners as possible. Adjust and tighten the M8n nuts. Rotate the Y-axis stage and repeat.
Make sure Y-corners are vertical. If not, insert the spanners between the M8 threaded rods. Use any fabric to protect them from scratching. Push the spanners to straighten the corners.

Correct bearing orientation
Correct bearing orientation
When placing bearings onto the Y-carriage, make sure that they are oriented as shown in the picture. One of the tracks has to be in line with the cutout for the bearing!
This orientation has to be followed in all 3 bearings on the Y-carriage!
Marker on the Y-carriage must be facing the table (not visible)!

Begin by locating the marker, at this step the marker should be facing the table (not visible) and only then you can add the bearings. If you place bearings to the same side as marker, you will have issues later!
Insert a 3x20x16 u-shaped bolt into the Y-carriage as shown on the picture.
Place the linear bearings in cutouts.
On side with two bearings slide bearings to the center, towards each other as close as possible.
DON'T tighten the u-shaped bolts!!! Wait for the next step.

Use pliers to tighten the u-shaped bolts.
Step 1: place the nuts (M3nN) on the u-shaped bolt and insert a bearing.
Step 2: using pliers tighten the nuts until you reach the surface of the Y-carriage, then stop tightening!
Step 3: use pliers again and rotate with the nuts only 1/4 of circle to finish the tightening. Tighten all six nuts this way.
Don't tighten the nuts more than it is described above or you will deform the bearings!
Tighten the Y-idler

Step 1: Place the motor temporarily in the frame next to the Y-motor part. See the first picture.
Step 2: Take the Y-motor-distance and place it at the very end of the motor casing. The two half-circle cuts on Y-motor- distance printed part must be facing the threaded rods. See the second picture.
Step 3: Take the motor away and press the Y-motor-distance printed part towards the threaded rods all the way in. See the third picture.
Note the correct orientation of the cutout for motor wires, it's very important!
It is recommended to use motor labeled "Y axis" as you will need it for the next step.

Insert the Y-axis endstop connector between the motor and threaded rods.
Gently pull the connector of the cable in the direction away from the frame (see the picture).
Using the 2.5mm Allen key, secure the motor to the 3D printed part.
Tighten the motor gently to avoid damage to the 3D printed part.
Endstops are part of the box 2.3.4.5.SUP.

Ziptie the cables to the threaded rods as shown in the picture.
Cut and discard excess ziptie.
Tighten the zipties carefully to avoid damaging the wires.
Be careful while cutting the zipties to avoid cutting the wires.
Levelling the Y-axis
Levelling the Y-axis
Levelling the Y-axis
Place the assembled Y-axis on a flat surface.
Check if every corner is touching the ground.
If some corner is in the air, try twisting the axis slightly.
You can also check it by tapping each corner and listen if it's making any noise.
This is your last chance to ensure the Y-axis is perfectly angled and level. It'll save you a lot of hassle later!
You can use aluminium frame for check, but be careful for possible scratches.

Move the Y-carriage as close as possible to the Y-end-motor.
Make sure that you heard the "click" sound and the Y-endstop is triggered as shown in the picture.
The colors on the picture are a bit over-saturated to highlight the endstop button.
Double check the Y-carriage!
Double check the Y-carriage!
This is a crucial part of the assembly. Please check again you can see the marked part of the Y-carriage (as shown in the picture), otherwise your heatbed won't fit properly!
