Start by placing the plastic part over the stepper motor.

For some wiring consideration, make sure that the stepper motor wires are placed on the same side as the big hole on the side of the plastic part as shown on the picture.

 

 


Insert and screw the 4 M3X8mm screws at each corners of the plastic part.

If you have a magnetized screw diver, this will help you achieve that.

If not you can use the cylindrical imprints on each corners to slide the screws up to it’s final location.This should help you to screw everything together

 


Once all 4 screws in place, you should have something like on the picture:

 

 

 

 


Then insert the pulley on the motor shaft. The small slot at the bottom of the picture should be aligned with the middle of the pulley

Then insert the bearing inside the dedicated plastic cage.

 

 

 

 


Here is a back view of the assembly.

 

 

 

 


Take the fork shaped plastic stretcher and place in the middle of the fork the bearing assembly. Then add a M3x25with a washer on one side and close it with a washer and a M3 Nut.


Now insert on the small slot on the side of the fork stretcher a M3 Nut that should fit perfectly inside.


Take a moment to make sure that the hole of the Nut is aligned with the one of the Fork stretcher at the back of it.

 

 

 


The final part should look like the picture:

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

  • 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.
