⬢Y-axis-corners
⬢Y-belt-holder (can also look like in the third picture)
⬢Y-motor-holder (can also look like in the second picture)
⬢Y-idler
⬢PSU-Y-part
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 100mm distance between a washer after counter-nut and the Y-axis corner. Use photo as 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).
Use M8n nuts (8 pcs), M8w washers (8 pcs) and M8 threaded rods (2 pcs).
⬢Screw the nuts and place washers and Y-motor-holder on threaded rod as shown in the picture.
Y-motor-mount should be somewhere in the middle of the threaded rod. The precise position doesn't matter at this time.
Ensure the correct orientation of Y-motor-holder.
Use M8n nuts (6 pcs), M8w washers (6 pcs) and M8 threaded rods (2 pcs).
⬢Screw the nuts and place washers and Y-idler on threaded rod as shown in the picture.
Y-idler should be somewhere in the middle of the threaded rod. The precise position doesn't matter at this time.

⬢Prusa i3 frame
⬢Y-axis stage
⬢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!
⬢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.

⬢Place Y-belt holder on the Y-carriage as shown in the picture.
⬢M3x12 screw (2 pcs)
Be aware of the orientation of Y-belt holder (belt entry should face towards single bearing).
There's no thread in Y-carriage, just push the screws all the way in.
⬢Use the mid-sized smooth rods (330 mm).
⬢Insert the 8mm smooth rods into the linear bearings on Y-carriage.
Be very careful! Insert the rod straight into the bearings, do not apply too much force and do not tilt the rod!
⬢Insert the assembled Y-carriage into the Y-axis stage.
Ensure the correct orientation of parts (Y-motor mount on the right and the single bearing on the bottom).
⬢Note location of the Y-carriage orientation marker - it's important Y-carriage is oriented as in the picture !
⬢Insert zipties into holes in Y-corners.
Ensure the correct orientation of zipties (head of the ziptie should be facing out from the Y-axis stage).

⬢Veďte řemen kolem kolíčku tak, jak je znázorněno na obrázku.
⬢Push the belt all the way into the belt holder.
⬢Place a GT2-16 pulley on the Y-motor shaft as shown in the picture.
One of the screws must be facing directly against the pad (flat part) on the shaft. Note you don't have to remove the motor from the frame.
Don't tighten it yet, we'll get to that later.
⬢Run the Y-axis belt through the Y-motor pulley and the Y-idler part.
⬢Undo the M3x10 screw.
⬢Otáčejte motorem, dokud nedosáhne na zem, jak je znázorněno na obrázku.
This step is illustrative, you don't have to remove the belt
⬢Using the pliers, insert the belt and insert the flat part it into the Y-belt holder as shown in the picture.
⬢Then guide the belt around the bottom pit as shown in the second picture.
⬢Using the pliers insert the belt all the way into the belt holder.
Do not cut any excess of the belt, it should be evenly distributed on both sides as shown in the picture.
The belt shouldn't be tight at the moment.
⬢Otočte motor zpět
⬢Screw in the removed M3x10 screw.
If you have to apply too much force and experiencing troubles, rotate the motor back, repeat previous step while making the belt more loose.
The belt should be quite tight, check it by pressing together both sides in the middle of the frame by gentle force.
⬢Insert the Y-GT2 belt (shorter one) in the Y-belt holder. Run the Y-axis belt through Y-idler part and the Y-motor pulley. insert the belt all the way into the belt holder.
⬢The belt should be quite tight, check it by pressing together both sides in the middle of the frame by gentle force.
Video is available in an online (digital) version only.
Video is showing belt assembly on slightly different version of the printer, but the principle and components for this step are identical.
⬢Adjust the Y-idler as shown in the picture (623h bearing housing should be in axis with the belt).
⬢Move the Y-carriage as close as possible to the Y-end-motor.
⬢Before tightening the nuts, ensure the Y-idler is in horizontal position.
Tighten the M8n nuts gently to avoid damaging the 3D printed part.
⬢Adjust the Y-motor-mount as shown in the picture (the belt must remain straight and the motor should not collide with the Y-belt holder part).
⬢Make sure that you heard "click" sound and the Y-endstop is triggered.
The belt part of the pulley has to be in axis with the belt itself.
Tighten the M8n nuts gently to avoid damaging the 3D printed part.
⬢Tighten the screws in the pulley.
One of the screws has to be tightened directly against the pad on the shaft.
Keep a small gap between the motor and pulley.
⬢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.
⬢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.
⬢Stick the felt pad on each Y-corner.
Felt pad is in the box 2.3.4.5.SUP
⬢Move the Y-carriage as close as possible to the Y-end-motor.
⬢Make sure that you heard "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.
This is crucial part of the assembly. Please check again you can see marked part of the Y-carriage (as shown on the picture), otherwise your heatbed won't fit properly!
⬢Congratulations, you have assembled Y-axis !
⬢You can continue by assembling X-axis in the next chapter - 3. X-axis assembly [Překládá se]
