5-7 Material cannot be cut through

FLUX Support Team
  • Updated

Description:

When the material cannot be completely cut through, there are many possible causes, such as focus error, optical path misalignment, laser tube attenuation, etc. Please follow the steps below to determine the cause of the problem.

Possible Causes

  1. Optical Path Alignment (OPA) misalignment.
  2. Incorrect focus distance.
  3. Dirty or damaged mirrors.
  4. Dirty or damaged focus lens.
  5. System failure (Update firmware, restore factory settings, or re-flash SD card).
  6. Incorrect power and speed settings in the software.
  7. Laser tube attenuation (aging).
  8. The material is difficult to cut.
  9. Laser Power Supply (Laser PSU) failure.
  10. Honeycomb platform is not level (Low probability).

Step 1 - Clean All Mirrors and Focus Lens

Excessive dirt on mirrors and the focus lens will affect the energy of the laser output. 

  • Please refer to the link below to clean all lenses.

Step 1.1 - Confirm correct parameter settings

Incorrect parameter settings in Beam Studio or on the machine panel can lead to failed cuts.

  • Beam Studio:
    Step
     
  • Machine Panel:
    (Ensure Speed and Power ratios are set to 100%)


     

Step 1.2 - Check the focal length
 

Incorrect focal length will result in cutting or engraving effects that do not meet expectations. Additionally, Beambox 2 can be set with two different focus modes; you must confirm that the focus lens position matches the selected focus mode.

Step 1.3 - Check the optical path

Based on our experience, when materials cannot be cut through, the most common reason is usually optical path misalignment.

  • Please refer to the link to check the optical path. If misalignment is found, please click the link in the text to adjust it.
    Optical Path Check
     
  • After completing the check, please keep the collected tape.
     
  • Before proceeding to the next step, please note:
    All steps after 1.3 assume that the optical path is perfectly aligned.
    If you still cannot confirm if your optical path is good after reading the above article, please stop here and directly contact your local dealer or FLUX technical support for assistance.
    (Collecting tape will be key information for locating OPA issues.)

Step 1.4 - Execute the same task

  • Use the same material to execute your original task and see if it can now be cut.

Determine the next action based on the result:

  • Yes, it can be cut now >> Problem solved
     

Step 1.5 - Prepare test materials

For further testing, please prepare any of the two materials listed below.
 

  • 3mm transparent acrylic board (Recommended) or 3mm wood board

Step 2 - Center cutting test

We will test the cutting capability at the center of the work platform.

  • Place the prepared material (3mm acrylic or wood board) at the center of the work platform and confirm focus is complete.
     
  • Cut the example file in Beam Studio.
    Step


Determine the next action based on the result:

Step 2.1 - Restore Factory Settings

Sometimes firmware glitches can cause abnormal laser output.
To rule out firmware issues, please reset the machine.

  • Restore the machine to factory settings.
    (Home > Machine > Next Page > Factory Reset > Yes)

     
  • After resetting, please cut the example file again, as in Step 2.

 

Determine the next action based on the result:

Step 3 - Bottom-right corner cutting test

In this step, we will test the cutting capability in the bottom-right corner area of the work platform.

  • Place the prepared material (3mm acrylic or wood board) in the bottom-right area of the work platform and confirm focus is complete.

     
  • Cut the example file in Beam Studio.
    Step


Determine the next action based on the result:

  • Yes, it can be cut in the bottom-right area >> Machine should be fine >> The problem may be related to the material. Please adjust parameters yourself (increase power, decrease speed, or increase repeats).

Step 4 - Door sensor test

If the door sensor is not sensitive enough or the magnet is not strong enough to fully trigger it, the laser output may weaken. In this step, we will use two magnets on the door sensor to ensure it is fully triggered.

  • For safety, please set the power to x0.01 to ensure no laser pulses are generated during testing.




     

  • The door sensor is embedded in the chassis LED light. Watch the video below to locate it.

    Step
     

  • The door sensor will have two red LEDs that are constantly ON.
    Step
    Step
     
  • Bring the magnets close to the two red LEDs. When the magnet is detected, the red light should become "brighter." When both LEDs detect magnets at the same time, a door-close signal is sent to the system, and the icon on the panel will change.  
    Step
     
  • After placing the magnets, close the door.
    Step
     
  • Adjust the power setting back to 100%.

     
  • Execute the same task and observe the results.
    • If the center area failed last time, retest the center area.
    • If the bottom-right area failed last time, retest the bottom-right area.
       
  • After executing the task, turn off the machine and remove the magnets.

 

Determine the next action based on the result:

Step 4.1 - Back cover sensor check

  • For safety, set the power to 0% to ensure no laser pulses are generated during testing.




     

  • Open the back cover and locate the back cover sensor.
     
  • The back cover sensor has two red LED indicators that are constantly ON.

     
  • Bring the magnets close to the two LED indicators. When the magnet is detected, the indicator should "brighten." When both LEDs detect magnets at the same time, a door-close signal is sent to the system, and the panel icon will change.
    Note: The LEDs are polarity-sensitive. You may need to flip the magnet or approach from the other side of the LED.

 

  • After placing the magnets, close the back cover.

 

  • Change the power ratio setting back to 100%, confirm the icon shows as closed,
    then perform a laser pulse. (Refer to the  examples to judge burn marks.)
    For HEXA RF 30W, perform 5 pulses.
    For HEXA RF 60W/80W, perform 2 pulses to avoid ignition.

Determine the next action based on the result:

  • Value is always within normal range >> Step 4.3
  • Value is persistently below minimum >> Step 4
  • Value is always above maximum range >> Step 6.1
  • Value fluctuates between normal and maximum >> Step 6.1

Step 7 - Report to local dealer or FLUX support team:

  • Please follow the instructions in the linked article to report the problem to your local dealer or the FLUX support team correctly. [Contact Customer Service] 

Information collected in this article, such as photos or videos showing machine problems, will need to be shared with the dealer or the FLUX support team.
