Description

The reasons for being unable to use the camera function can be complex, potentially caused by hardware, software, a poor connection environment, network speed, and other factors. This article will guide you on how to determine whether it is a hardware or software issue.

Possible Causes:

  1. System failure (Update firmware, restore factory settings, or re-flash the RK mainboard).
  2. The camera parameter is missing (Do advanced camera calibration.)
  3. Network speed is too slow.
  4. Unstable network environment.
  5. Issues with Beam Studio software.
  6. Abnormal hardware connection of the camera cable.
  7. Camera cable failure. 
  8. Camera module failure (Low probability).
  9. Issues with RPi/RK mainboard (Low probability).

Step 1

Please refer to the video below to test whether the camera image on the screen is normal when the laser head moves in Action mode.
Place a board or a piece of paper in the center of the work platform to observe the camera image.
"Action" > "Camera" > Unlock Motor > Open door > Move to four corners.
(Note that the camera updates the image every 3 seconds)

 

Evaluate the result and take the next action: 

  • Image is normal, as shown in the video. >> Step 1.1
  • Image is present but freezes when moving.>> Step 3
  • Image is present but turns blank when moving.>> Step 3
