Atom Printer Inspection


       Inspection 1 :  

       Ensure that there are no gaps between the aluminum                    extrusions and the corner pieces.




       Inspection 2 :

       Ensure that the carriages are tightly fastened onto
       the X, Y, Z axis slider tracks and make sure the belts
       are not too loose.





        Inspection 3 :

        Ensure that the end-stops of the X, Y, Z axes
        are pushed to the top ends and that they are
        securely fastened.




        Inspection 4 :

        Ensure that the headless hex screw on the
        timing pulley is securely fastened.




          Inspection 5 :

          Ensure that the wire tube has enough slack so
          that there will be no tension when the effector is
          extended to the most extreme range.



Nozzle Inspection

Inspection 1 :
Ensure all the ball joints are fastened as
close to the hub’s surface as possible.
Screw threads should not be visible.

Inspection 2 :
Ensure the hotend assembly is securely
fastened to the top cover of the effector.

Inspection 3 :  
Ensure top cover securely
fastened to the effector.

Inspection 4 :  
The screw with the spring must be mounted
with a washer to prevent interference.

Inspection 5 :  
Ensure the appropriate sleeve and washer are
properly installed between each side fan and  the top cover.


Inspection 6 : 
Press the hotend from below with your index finger. A clicking sound should be heard at every light press, which indicates the Auto Level function will be ready to use.

Inspection 7 :  
Ensure that the fans are securely fastened and that the fan shields are properly installed.

Wire Connections Inspection

               fig.1 - Wire Connections At The Top Of The Printer



Inspection 1 :

Ensure that all connections match the colors as seen in the assembly manual or below (fig.1). If components seem to not work during the print test later on, be sure to check the connections. If you have a multi-meter, it is good practice to check if current can run through connections.

Inspection 2 :

Ensure that all connections match the colors as seen in fig.2 .

Make sure the side fan's (Black & Red) connection is well connected to metal instead of plastic skin


Adding Lubrication

Before your first print test, it is recommended to apply lubricant on all joints of the moving parts if you have not done so already:

1. Apply a drop of lubricant to each tip of the rods

2. Apply some lubricant to the top of each slider and slide it up and down

After applying lubricant, friction in the moving parts should be noticeably and significantly reduced.Proper lubrication is important to printing quality and ensuring key components’ longevity. Be sure to check lubrication regularly (weekly if frequently used) when using your ATOM 3D printer.


(ATTENTION: If the carriage is linked to the motor and the motor is linked to the main control board, be sure to only slide very slowly, as sliding faster will cause reverse current and may permanently damage your main board.)

Selecting a Lubrication

WD40 works well for removing rust and adhesives, but it is not a suitable as a lubricant for use on the ATOM 2.0 parts. When parts such as bearings are sprayed with WD40, it washes out the heavy duty lubricants housed inside and will shorten the bearing’s life by increasing wear and tear.

Non-corrosive lithium-based grease is recommended for lubricating ATOM 2.0 metal parts. The lubricant provided in your package is suitable for use on the ATOM 2.0.

Keep in mind that sewing machine oil has a relatively low viscosity and may evaporate quickly. Sewing machine oil may also contain substances that will corrode some plastics and rubber.
