Description

The reasons for not being able to use the camera function are complex and may be caused by hardware, software, poor connection environment, network speed, etc. This article will show you how to determine a hardware or software issue.

The applicable models of this article are HEXA, Beambox Pro, Beambox, and beamo.

 

If your camera displays the images but the image shifts, blurs, or the previewing process is way too slow, etc., please check the following articles.


Possible Causes:

  1. The system fails (Re-update the firmware, reset to factory, or reflash SD card.)
  2. The internet speed is too slow.
  3. The network environment is not healthy.
  4. The software, Beam Studio is having a problem.
  5. The physical connection of the camera cable is improperly connected.
  6. The camera cable is having a problem. 
  7. The camera module is having a problem. (Less likely)
  8. The RPi/RK board is having a problem. (Less likely)

 

Step 1

Please refer to the following video to test whether the camera image on the screen is normal when the laser head moves in control mode.
Please place a board or paper in the middle of the bed to facilitate observation of the camera's image.
"Control" panel > "Camera" > Open door cover > Click "D" > Click "B" > Click "C" > Click "A"
(Note that the camera updates the image every 3 seconds)

 

Determine the result and the next action to take:

  • The image is normal, as in the video. >> Step 2
  • It has an image, but when moving, it freezes. >> Step 3
