Pronterface can be used to control ATOM:

1.  Click the left side buttons to move 3 axis or heat up the hotend.

2.  Test the end-stops' statuses by typing in the command inthe text box.

Follow the directions below to test your ATOM's end-stop status.

 

[Cautions] :

Double check that all wires are connected and plugged in the right places.
Make sure the main power terminals are not reversed.
Make sure the orientations of the DRV8825 chips are correct.
Make sure the pins are correctly plugged in.

Incorrect installation of any of these items may cause permanent damage if powered on!


End-Stop Test

1.  Lower the effector by hand so the 3 carriages are         not touching the end-stops at the top.

2. Download Pronterface from the URL or Google it.

3. Plug the printer to your computer via the USB cable,       power on the printer.

4. Install and run Pronterface.

 


5. Select the right COM Port that is used to                       communicate with the printer .
    [To find the COM Port # in Windows, right click "[My]     Computer" > Manage > Device Manager > Ports COM     & LPT > Look for "USB Serial Port (COM ####)"]

6. Select @250000.


7. Click the [Connect] button.


8. If the connection is successful, messages should             appear in the text box. If there is no response, check     your USB connection, printer power, and click                 [Connect] again.

9. Test the end-stops' statuses by typing in the                 command [M119] in the console and clicking [Send].


10.  The console should report that all end-stops are             open:

      X_max: open
      Y_max: open
      Z_min: open
      Z_max: open

 

 

If all end-stops report correctly, click the [Home] icon on the bottom left corner and the 3 carriages should move to the very top.

 

Troubleshooting

If an end-stop is reporting triggered, make sure that the corresponding end-stop switch is not in contact with anything. If an end-stop is not in contact with anything and is still reporting triggered, then check for faulty connections to the main board or the wire connections at the end-stop terminals. If neither are the problem, then check to make sure the wires are intact. If wires are cut, then it will require a reconnection or soldering.



10.  If all end-stops report correctly, click the [Home]           icon on the bottom left corner and the 3 carriages         should move to the very top.

11.   Type the [M119] command again and press [Send]
 

 

 

12. The console should report that all end-stops except Z_min are triggered.

      X_max: triggered   (X axis' end-stop )
      Y_max: triggered   (Y axis' end-stop)
      Z_min: open          (Nozzle's end-stop )
      Z_max: triggered   (Z axis' end-stop)

 

While pressing in and holding the bottom of the hotend (do not do this when the hotend is hot), use the the [M119] command again and Z_min should report triggered:  

      X_max: triggered   (X axis' end-stop ) 
      Y_max: triggered   (Y axis' end-stop)
      Z_min: triggered    (Nozzle's end-stop )
      Z_max: triggered   (Z axis' end-stop)

 

13. If all steps were completed without problems, you are now ready for the next test!


Troubleshooting

 
fig.1 - Stepper Motor Cable Plug Orientation


fig.1 - Stepper Motor Cable Plug Orientation


If a stepper motor runs in the opposite direction to the other axes, power off the printer before any collisions occur.

1.  Check the orientation of the corresponding motor         cable plug on the main board to see if they match         the diagram (fig.1)

2.  Check the orientation of the corresponding                    DRV8825 chip to see if it matches the diagram on          the manual (fig.1)

 

Hotend Heating Test

 

1.  Make sure your printer is powered on and connected     to your computer via USB, and that Pronterface is           connected to your printer.

2.  In the [Heater] selection menu, choose [185 (PLA)] or      input 185 if the selection is not there.

3.  Click the [Set] button directly left of the selection          menu.

4.  Click the [Check temp] button to monitor the                hotend’s temperature.

5. If everything is operating normally, the temperature       graph should rise up and eventually reach 185               degrees.

6. Press the [Off] button next to the selection menu           once the temperature successfully reaches 185.

 

 

 

 


[Cautions] :
Even after you press the [Off] button the hotend will still take time to cool down, touching it while it is cooling down will still result in burns.
