#913 Abnormal Air Flow Detection

FLUX Support Team
  • Updated

 

Possible causes:

  1. The system fails (Re-update the firmware, reset to factory, or reflash SD card.)
  2. The air hose is bent or damaged.
  3. The 3-way transparent tube (T-joint) on the sensor is bent or damaged.
  4. The mainboard/MB/motherboard is malfunctioning.
  5. The air pump is too weak.
  6. The air pump is too strong. (Less likely)

 

Step 1

Test if there's air blowing out from the laser nozzle.

  • Enter the Maintain mode on the panel and enable the air pump.
  • Use your hand or a piece of paper to test if there's air blowing out from the laser nozzle.

 

Determine the test result and the next action to take.

  • Yes, there's air blowing out >> Step 2

 

Step 1.1

Remove the side cover to check or re-connect the two air pump wire pins and the air hose connected to the top of the air pump.

  • Turn off the machine. Remove the side cover by unscrewing these T8 screws and unplug the two USB extensions. (Refer to the diagram if your PCB board is not the same as the photo.)

 

  • Check or re-connect the two air pump wire pins.

 

  • Check the air hose on the air pump.

 

  • Check the air hose on the laser nozzle. (The shield has to be removed.)


 

  • Turn on the machine and enable the air pump to test whether air is blowing out from the laser nozzle.


Determine the test result and the next action to take.

  • Yes, there's air blowing out >> Step 2
  • No, there's no air blowing out >> Step 1.2

 

Step 1.2

Reset the machine to the factory and test if there's air blowing out from the laser nozzle.

5-30 Reset to Factory

 

Determine the test result and the next action to take.

  • Yes, there's air blowing out >> Step 2
  • No, there's no air blowing out >> Step 1.3

 

Step 1.3

Reflash the SD card and test if there's air blowing out from the laser nozzle.

Determine the test result and the next action to take.

  • Yes, there's air blowing out >> Step 1.4
  • No, there's no air blowing out >> Contact Customer Support
    • Possible cause:
      1. The air pump is faulty and needs to be replaced
      2. The mainboard is faulty and needs to be replaced

 

Step 1.4

Enable the airflow value on the panel and move the laser head around the work area to see if the value changes while moving the laser head.

 

Determine the test result and the next action to take.

  • The value is always within the normal range >> Step 1.5
  • The value is always smaller than the Min. value>> Step 3
  • The value is always bigger than the Max. range >> Step 4
  • The value changes within normal and the Max. value >> Step 4
