5-28 Camera Offset Manual Adjustment

Description

If you are experiencing an offset between the actual engraving position and the photo position previewed by the camera, please try to use the following steps to manually adjust the camera's preview position.

_______________

 

Tools：

• A flat A4 printing paper
• Wood/MDF x 4pcs (Must be the same thickness, flat, size: 5cm x 5cm or above)

_______________

 

Step 1 - Firmware Version Check

As this function is only available in firmware version 5.1.9 or above, make sure your firmware version is up to date. 
Please refer to the following instructions to check the firmware version and update the firmware.
Firmware Update

_______________

Step 2 - Perform Camera Calibration

The purpose here is to ensure that the center area in the camera preview is accurate.
Please use the prepared A4 paper and follow the instructions in the link below to perform camera calibration.

Step 3 - Flatten the Aluminum Sheet

An uneven sheet at the bottom will cause the adjustment to be incorrect. Therefore, flattening the sheet with a board will be necessary. 

_______________

 

Step 4 - Place the Wood Pieces in the Corners

Place the wood pieces according to the photo below. Matching the edges of the sheet and the wood will be suggested. The wood pieces are not necessary to be pushed outward to the frame.

_______________

 

Step 5 - Perform Auto-focus at the Top-left Corner

As in the photo below, manually move the laser module to the area circled in red and perform auto-focus. (Use the physical button or the touch panel - main page)

_______________

 

Step 6 - Close the Door and Check if there's any Gap

After closing the door cover, make sure there's no gap between the door cover and the frame.
If it cannot be closed without a gap or rebound, this may be because the door cover is too tight. Please refer to this page to lubricate the door cover.

Good Example - No Gap：

_______________

 

Step 7 - Download the Testing File

Please download the file according to the module you have.

• 10W Diode Laser Module
• 20W Diode Laser Module

_______________

 

Step 8 - Beam Studio Version Check

As this function has to be used with the auto-preview function which is only available in Beam Studio version 2.2.9 or above, make sure your Beam Studio is up to date. 
Please refer to the following instructions to check the BeamStudio version and re-install it if necessary.
Software Download

_______________

 

Step 9 - Run the Testing File

Launch Beam Studio and load the testing file.
Take one shot using the camera preview to make sure those four red cubes are on the wood pieces then start the task.
(Do not open the cover or move the wood pieces as the later steps will be done using the software or the touch panel)

_______________

Step 10 - Take another Shot after Task Finished

After finishing the task, do not move the wood pieces or open the door cover.
Please directly take another shot to see if there is an offset between the actual engraving and the photo. You can zoom in on the corners to check the cubes.

 

Good Example：

Perfect: The black cube matches the red cube	Good: Off a bit but acceptable.

NG範例：

The actual engraving (black cube) is to the lower left and needs to be adjusted.	The actual engraving (black cube) is to the right and needs to be adjusted.

Step 11 - Go to the Adjustment Page on the Panel

• Go to the page using the panel as shown in the video below.
• Please take a photo before changing any parameters in case of a situation that needs restoration.)
  
• Machine >> Settings >> Hardware Settings >> Camera Precision Adjust

Step 11.1 - Camera Offest Function Explained

• These 9 vaules represent the 9 areas in the actual area.
  
  
• Click on one value to adjust a single area.
  
  
  
• The arrows on the screen are for the above-mentioned blocks 1: top-left, 3: top-right, 7: bottom-left, and 9: bottom-right, to adjust the entire area in equal proportions.
  
  This means that when you use arrows to adjust a corner, the system will automatically bring in the values ​​​​in other areas to reduce the gap between the blocks, in case of causing the preview to be uneven or twisted.
  (In most cases, only arrows are used for adjustment.)
  
  
  
• "all 0" is to make all the values to "0".
  
  
  
• "Save" is to save the change. Every time you modify a value or more, it's necessary to click the "Save" button. Otherwise, the changes won't be saved.
  
  
  

_______________

Step 11.2 - The values in relation to the preview explained

Because the principle behind this adjustment is relatively complex, users only need to remember the following formula:

• Increase the value = shrink the screen = shrink the engraving black cube
  (The larger the value, the screen shrinks more)
  
  

  
  Example of Increasing the Value：

  
  
  

 

• Decreasing value = Pushing screen outward = Pushing the engraving black cubes outward
  (The smaller the value, the screen will be pushed more)
  
  

   

  Example of Decreasing the Value：

_______________

 

Step 12 - Enable the Auto-preview Function in Beam Studio

In Beam Studio, after clicking on the camera icon, there will be a circle icon. Click on the circle icon to enable the auto-preview function meaning the camera will continuously take photos.

 

_______________

Step 13 - Start Adjusting

The adjustment method is to first change the parameters on the machine's touch panel and press "Save". After that, check on the software to see whether the actual engraving black cubes are getting closer to the red cubes.
(Moving the computer closer to the machine is recommended for an easier adjustment.)

When the black and red cubes are matching each other, the adjustment will be done.

If you are still confused on how to adjust, you can refer to:

• Videos in Step 11.1 - Camera Offest Function Explained
• Examples

_______________

Examples

Example #1 - Black Cubes are all Located Outwards of the Red Cubes:

Suggestion:
Increase the values in all four corners to make the cubes shirk. You can also refer to the video.

_______________

 

Example #2 - Black Cubes are all Located Inwards of the Red Cubes

Suggestion:
Decrease the values in all four corners to make the cubes shirk. You can also refer to the video.

 

_______________

Example #3 - Only One Black Cube is Off:

 

Suggestion:
According to the offset in the photo above, the bottom-right black cube is off outwards.
Please increase the value for the bottom-right area to make the black cube shirk


As increasing the values for the bottom-right will also increase other areas, please decrease other areas' values slightly.

_______________

Example #3 - The Black Cube is off to the Right or the Left:

Suggestion:
According to the offset in the photo above, the top-left black cube is off to the left of the red cube and the bottom-right black cube is off to the right of the red cube.
Increase the values of the top-left corner to make the top-left black cube shirk.
Increase the values of the bottom-right corner to make the bottom-right black cube shirk.

Increasing those two values would also increase the other two, so decreasing the other two's values slightly would be necessary.

This example may not align perfectly with the red cubes, so the ideal situation may be to adjust to an acceptable range.
(If it cannot be adjusted to an acceptable range, please take a screenshot of your preview photo and contact customer service directly.)

Top-left: Acceptable example	Bottom-right: Acceptable example

 

_______________

 

Example #4 - Irregular Offset

Suggestion:
According to the offset in the photo above, all four black cubes are off in different directions.
This won't be possible to be fixed by adjusting. Please take a screenshot of your preview photo and contact customer service directly.
_______________

 

Example #4 - The Offset is too Big:

Suggestion:
According to the example in the photo above, the offset is greater than the size of a red cube.?
It is not recommended to adjust this.
Please take a screenshot of your preview photo and contact customer service directly.

_______________

Example #6 - The Preview is Twisted after the Adjustment:

Suggestion:
According to the example in the photo above, the difference between the values set may be too big.
It is recommended to reset it to zero ("all 0") first and then readjust it again.
Please give priority to using the arrows to adjust first, rather than making individual adjustments.

After the re-adjustment, even if the red frame and black frame merge, the captured image is still distorted, this would be considered unacceptable.
Please take a screenshot of your preview photo and contact customer service directly.
