  • Updated

Note:

The first-level calibration of the camera modifies the underlying data of the system.
Once done, the original data can't be restored. Please proceed with caution.
If you are not sure whether the camera needs first-level calibration or not, please contact support@xtool.com for further advice.
 

Camera Positioning Error

  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.

After the first-level calibration is complete, please calibrate the auto-measurement to avoid significant errors in the measurement result.
 

Application Scenario

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.

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.

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.

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.
