  • 2 x 660x10mm
  • 3 x LM10UU bearings
  • 2 x 625ZZ bearings
  • 1 M3x16 screw
  • 1 M3 nut
  • 1 x XMI 10 plastic part (Idler support)
  • 1 x XMII 10 (motor support)
  • [Not provided] 1 x hammer
  • [Non provided] 1 x bubble level

Scalar M List of parts :

  • 2 x 435x8mm
  • 3 x LM8UU bearings
  • 2 x 625ZZ bearings
  • 1 M3x16 screw
  • 1 M3 nut
  • 1 x XMI 8 plastic part (Idler support)
  • 1 x XMII 8 (motor support)
  • [Not provided] 1 x hammer

Scalar XL: Take the plastic part marked XMII and 2 660mm long, 10mm diameters smooth rods

 

Scalar M: Take the plastic part marked XMII and 2 x  435 long, 8mm diameters smooth rods

 

 

 

 


Approche the smooth rodes from the plastic part

 

 

 

 


Scalar XL: Push the rods inside the round slot on the plastic part of about 4.3cm . The pictures shows you how much the smooth rod is inside the plastic part.

 

Scalar M: Push the rods inside the round slot on the plastic part of about 2.5cm .

 

 


If you struggle in pushing the smooth rod inside , use a hammer and give some small sharp hits on the other side of the smooth rods. They will get inside little by little.

 

 

 


Here the pictures shows 1 smooth rod completely inside and the other one in the process of getting inside.

 

 

 

 


Once both smooth rods are in place, you will have something similar to the picture.

Notice on the picture that the top of the plastic part is indeed at the bottom of the picture.

 

 

 


Scalar XL: Once both smooth rods inside their slots, insert 2 x LM10UU bearings on the top rod and only 1 on the bottom rod.

Scalar M: Once both smooth rods inside their slots, insert 2 x LM8UU bearings on the top rod and only 1 on the bottom rod.

 

You can figure out what is the top side easily. The marking is made so that when you read it on the proper side.

 

Pre assembled kit: Inside the pre assembled kit, the X carriage will already be mounted with the Linear bearings .You need to position it as shown on this picture.

 

 


Scalar XL: Once the bearings are in place, take the other plastic part marked XMI 10 And push the available sides of the smooth rods inside.

Scalar M: Once the bearings are in place, take the other plastic part marked XMI 8 And push the available sides of the smooth rods inside.

 

This side should be easy to insert.

 

 


Once the smooth rods inside push the plastic part so that the rods are on the edge of the plastic part.

 

 

 

 


You can use a hammer and hit the middle of the plastic part if you struggle doing it!

 

 

 


Here is the result if you have it right.

X axis with the pre assembled X carriage

X axis belt setup

List of parts

  • 3 M3x20 screw
  • (Scalar XL) 1 M3x50 screw
  • (Scalar M) 1 M3x30 screw
  • 1 M3 nut
  • 1 M3 washer
  • 2 plastic washers
  • 1 625ZZ bearing
  • 1 plastic cage for 625ZZ bearing
  • 1 plastic fork stretcher
  • 1m40 GT2 2mm belt
  • (Scalar XL) 1 XCA 10 plastic support
  • (Scalar M) 1 XCA 8 plastic support
  • 1 GT2 16 teeth pulleys
  • 5 cable ties
  • 1 stepper motor
  • [provided] 1 allen key
  • [not provided] 1 cruciform screw diver
  • [not provided] 1 cutting pliers or pair of scissors

 

Insert the bearing inside the plastic cage

 

 

 

 


Insert the plastic washers on the bearing

 

 

 

 


Place the bearing block inside the Fork plastic support as shown on the picture

 

 

 

 


Insert a  M3x20 screw + M3 washer and then close the whole system with a M3 nut.

 

 

 

 


If the carriage is already mounted you can scroll down to skip this part.

On X Axis slightly space the linear bearings and move them on the center on the axis.

 

 

 

 


The following steps explain how to assemble the X carriage called XCA 10 for Scalar XL and XCA 8 for Scalar M. You can now check that it properly fit on the bearings.

 

 

 

 


Place on the carriage 3 cable ties. In order to make things easier, be careful to properly place the cable tie heads on the outside of the plastic part as shown on the picture.

Also make sure the heads have at least 1 or 2cm of free length, this will makes things easier later on when you will tight them up.

 

 


The back view will give you more access to the cable ties and will make it easier to handle them.

 

 

 

 


Tight the cable ties so that the ties heads stay at the outside of the part.This will allows to have more free room for the belt later on.

 

 

 


Front view, the carriage looks like the picture.

Notice the cable ties that enroll the bearing.

 

 

 


Now take a stepper motor and 3 M3x20mm screws

 

 

 

 


Place the stepper motor on the left of the X axis.

The wires from the stepper motor needs to be oriented toward the machine .

 

 

 


Screw it entirely on it’s support.

 

 

 

 


The back view shows you how to position the cables. They will then be place inside the aluminum extrusion slot later on.

 

 

 


Now , install the pulley on the motor axis. Place it as shown on the picture so that the thicker part of the pulley is facing the opposite of the motor. This will allow you to properly align the pulley’s teeth with the belt slot on the stepper motor support.

 

 

 


This side you should help you understand how to align the pulley with the belt slot.

 

 

 

 


Now take the belt stretcher that you assembled at the beginning of this chapter.

 

 

 

 


Scalar M: Take also a M3x30 screw, a washer and a M3 nut.

Scalar XL: Take also a M3x50 screw, a washer and a M3 nut.

Place the nut inside the belt stretcher, there is a dedicated slot on the side of it.

The washer will be mounted on the screw and will help to tighten the stretcher.

 

 

 

 

 

 


Use the tensioner support and place it at the end of the X axis smooth rods.It’s purpose is to make sure the tensioner will force on the X axis smooth rods ends and not on the Horizontal Z axis smooth rods.

 

 


Place the screw and it’s washer on the side of the right side of the X axis.

She should be free and be fully inside.

 

 

 


Now place the stretcher inside the dedicated slot on the same plastic part.

Notice the triangular shape slot. The stretcher should be able to get inside properly.

 

 


Slightly screw the stretcher with the side screw.

The purpose here is to make sure the stretcher is in place and that we have the maximum amount of possible movement to stretch the belt later on.

 

 

 


A side picture showing the gap between the stretcher and the X axis plastic part. The screw should be able to move freely when moving the stretcher. (the tensioner support is missing on this picture)

 

 

 

 


This picture shows you how much length is available once the stretcher is fully pushed inside it’s slot. (the tensioner support is missing on this picture)

 

 

 

 


Depending how the belt is provided you will need to cut the 2.5m meter length of it or they will already be provided with the proper length.

 

 

 


Take the 1m40 belt (cut the 2.5meter belt at 1m40 if the belt is provided uncut).

Also take 2 cable ties

 

 

 


Insert the belt inside the slot of the stepper motor holder plastic part.

Insert it at the bottom of the bearings, the belt’s teeth facing the bearings.

 

 


On the other side, handle the belt so that it goes around the pulley.

With the belt’s teeth always facing the pulley.

 

 

 


Another view showing the belt

 

 

 

 


Take care to push the belt on top of the bearings. The bearing will keep the belt straight to the X axis carriage so that when the motor pull or push the belt, it’s always rectilinear and parallel to the smooth rods.

Then pull the belt so that at least 10cm are available in the void.

 

 


Now go the other side of the X axis, and take the bottom part of your belt.

Push it behind the X carriage.

 

 

 


Now insert it behind the stretcher. If you struggle you can unscrew the stretcher, pass the belt and then screw back the stretcher.

 

 

 


Here is a picture of the belt once inserted behind the stretcher.

 

 

 

 


Bring both ends of the belt together.

Those 2 ends must be located at the top of the overall belt assembly.

If you have the proper length, the belt should slight cross  with enough free belt.

Place it in the center of the X carriage

 


Take one end of your belt and push it inside the tight gap dedicated to keep the belt into position, between the 2 linear bearings.You might need to force a little bit so that the belt is slightly smashed between the plastic.

You can use your nails to push the belt up to the end of the slot.

 

 


Then round it so that the belt teeth can join. make sure you have extra length, you will need it to secure the belt later on.

 

 

 

 


Do the same on the other side of the belt.

At this moment try to pull the belt a maximum already so that it’s quite stretched .

Whatever you do, the belt will keep a small flexibility. It’s normal, the side stretcher will cope with that later on.

 


Insert a cable tie and start to close it but keep it loose. One side of the belt must fully be inside the closing cable tie. the picture illustrate this..

 

 

 


Now close the cable tie but make sure the belt stay aligned and parallel to the smooth rods. The belt must always be aligned at the top to keep the mechanical motion of the carriage linear.

 

 

 


Do the same with the other side of the belt.

 

 

 

 


Once finished it should look like the photo.

 

 

 

 


Take a screw diver and stretch the belt max . Make sure not to bend the Z axis however.

You know that your belt is stretched when it seems very hard by pressing on it.

Considering the length of the belt, even when properly stretched, it might still seem a little bit flexible or might vibrate a little bit. It’s normal it shouldn’t bother that much the printing but might impact the maximum acceleration you can use on that axis.

 

 

Setup of End stops

List of parts :

  • 1 smooth rod support integrating the pre wired end stop.
  • 1 x 8mm (Scalar M) or 10mm (Scalar XL)  smooth rod compatible end stop support
  • 1 End stop with a wheel
  • 2 sets of M6x12mm screw and it’s T-Nut
  • 2 cable ties

 

Assembly of the Y axis end stop

Take the plastic part looking like a hook and clips it over the smooth rod near the X axis motor support .

Here we placed it on the top rod, but you can place it on the bottom one if you feel the end stop doesn’t hit the X carriage

 

 

 


Now take the end stop with the wheel and place it so that the wires are on the outside of the machine toward the stepper motor, and make sure that the wheel is heading toward the smooth rod.

The main prupose here is that the wheel would hit the X carriage to signal to the electronic that the carriage has reached the MIN position on X axis.

 


In order to allow the more natural position of the end stop’s wire, just make sure they go behind the threaded rod, between the threaded rod and the aluminum extrusion as shown on the picture.

Also secure the end stop on it’s support using 2 cable ties.

 

 


Bring the X axis carriage against the end stop and check that the wheel is properly pushed by the carriage and that the probe wire is well positioned.

If the probe wire is causing trouble, you might consider placing this end stop on the bottom smooth rod.

Also check that the end stop support is  not moving on the smooth rod to avoid possible future issues.

 


This picture shows the front view. The end stop is pushed against the x Carriage.

At this moment check that the nozzle position over the heat bed is reaching the border of it. If it’s not the case, just readjust the location of the end stop a little bit in order to achieve this goal.

 


In order to make sure tat the end stop is properly attached to the smooth rod, you can constraint it using the cable tie and secure the end stop lead wire with it as on the picture making sure it’s going behind the threaded rod.

 

 


Y Axis End stop installation

We are going to install here the end stop of the Y axis .

This items should already be assembled . You might need to remove the protective scotch however before using it.

You should have on your chassis 3 identical heatbed smooth rod supports and 1 other with the integrated end stop holder.

It is to be placed on the opposite side of the power supply, also on the opposite side of the Y axis motor on the same extrusion profile.

 


These 2 pictures should help you to locate the proper position of it.on your machine.

 

 

 

 

 

 

 

 


Now take the M4x20 screw and it’s 2 M4 nuts.

 

 

 

 

 


Place the nut at the middle of the screw thread.

 

 

 

 


Under the heatbed, you should have a special LM8UU linear bearing holder with a hole dedicated to this screw .

 

 

 

 


You should have this support aligned with the end stop holder.

 

 

 

 


Now insert the screw inside up to the nut

 

 

 

 

.


Adjust the screw depth so that the nozzle tip reach the edge of the heat bed.

 

 

 

 

 


Secure the Screw using the left over M4 nut.

 

 

 

 

 


(Goodies) Assembly of the Y axis end stop

Now you are going to assemble the Y axis end stop.

Take the plastic support that is compatible with 30×30 slots.

Prepare a set of M6x12mm screw and a T-Nut.

Place the end stop so that the contact side is placed toward the outside of the part. Also  center the end stop so that the dedicated holes on the plastic part for securing the end stop are aligned with the end stop holes.

The photo shows you how to place it.

 


secure it wit 2 cable ties.

A good tip is to make sure that the cable ties heads are placed on the left of the plastic part. The picture should help you to place them properly.

 

 

 


Place the whole assembly on the side of the Y axis motor near the YMI marked plastic part.

The lead wire of the end stop can be placed like on the picture, afterward the motor wires and the end stop wires will follow the some path.

 


 

The inverted view shows how the end stop contact is located and how the wires are going to be placed.

This position is also nice to protect the contact metallic plate from being broken.

 


 

Installation the Y axis end stop finger

Under the heat bed, make sure to be on the opposite side of the heat bed power cable.

Now take as reference the linear bearing support located the closest to the Y axis end stop.

On this photo the Top left linear bearing support

 


 

From this starting point, measure 100mm (10cm) on the right of it and then go down 25mm (2.5cm). Then make a mark.

Then go right again for 10 mm (1cm) and make a 2nd mark.

Both marks will be used to locate the screws for the Y axis finger holder

 


Now take the finger holder and place the 2 wooden screws to secure it in place at the location of the previous marks.

 

A M3X20mm screw and 2 nuts are to be used in order to adjust the Y MIN position of the heat bed.
