1. In the laser flat mode, place a piece of flat material 3mm thick on the baseplate and do a scoring job.
2. After the processing is complete, click the "Refresh" button. Measure the shift distance between the scored pattern and the designed pattern. That distance is considered to be the position error.

Generally, the error value is less than 1mm when the thickness of the processing material is 3mm.

This article applies to troubleshooting the issues below.

1. Large errors in M1 camera positioning.
2. Significantly deformed baseplate image with M1 camera in laser flat mode.
3. Camera refreshing failure due to missing calibration file.

 

Tools Needed

1. Some pieces of A3 white paper.
2. A transparent or white tape.
3. One piece of acrylic sheet, A3 size, 3mm thick, or two pieces of acrylic sheet, A4 size, 3mm thick.

  Note:

• The acrylic sheet should have a flat surface, or it will affect the calibration result and the camera positioning accuracy.
•   A3 paper size stands at 297mm*420mm, while A4 is at 210mm*297mm.

 xTool M1 First Calib

 

How to Do

1. Download the calibration program and unzip it to a place other then the C Drive.

Note: In some conditions, your computer may forbid the software to access the C Drive.

 

2. Place two pieces of acrylic sheet, A4 size, 3mm thick, or one piece of acrylic sheet, A3 size, 3mm thick on the baseplate.

 

3. Spread a piece of A3 white paper on the acrylic sheet and fix the paper with tape.

Note: Make sure the paper is spread evenly.

 

4. Close the lid, and connect M1 to XCS with the USB cable.

 

5. Open the calibration file and run the main program below by double-clicking.

Note: If it fails, please run this program as an administrator.

 

6. Click "Connect".

 

7. Click "Process" and wait until the processing is complete.

 

8. Click "Snapshot" to capture the image.

 

9. Click "Generate" to generate the calibration file.

 

10. Check the calibration grid point.

• If red circles show up, it indicates there are large errors in the calibration result. Please calibrate the camera again.
• If yellow circles show up, it indicates there are slight calibration errors in this area. Please check if the grid line is deformed.

•  If the number of yellow circles is less than 20 and the grid line is not significantly deformed, please move on to the next step.
• If not, please calibrate the camera again.

 

11. Click "Update" to upload the calibration file.

When the uploading is complete, close the pop-up window.

 

12. Check M1 camera positioning accuracy with XCS according to steps in Camera Positioning Error above.

•   If the result is inaccurate, please calibrate again.
•   If not, please calibrate M1 auto-measure according to the link.
