1. Find the calibration software
Open the EzCad2 file directory and double-click “Corfile2” to enter the 9-point calibration software.
2. Set the calibration parameters
Click “F1 设置激光器参数” to set the laser type and marking parameters (normally, the marking parameters are default). In general, the fiber laser type is IPG, SPI, and is checked separately. Click “OK” to return to the previous interface.
3. Corrective operation method
Lay the black paper on the workbench and make sure the paper is flat. Then click on “F3 标刻9点测试矩形” and the following graphic will be marked.
The following dialog box will appear after each marking, and the next steps will be taken if the dimensions are appropriate. If the size of the corrected graphic is not suitable, click “Cancel” to return to the previous menu, click “F1 设置激光器参数“, find
, change the standard test rectangle size to large or small, confirm and return to the upper interface, then re-marking until the size is right.
The observation dialog box displays whether the image is consistent with the marking pattern. If they are consistent, continue with the subsequent steps; if they are inconsistent, click “更改图像类型” until the software display graphic matches the graphic marked on the black photo paper.
According to the coordinate position of each point corresponding to the graphic and the graphic displayed by the software, the 5th point is taken as the central coordinate (0, 0). Use a ruler to measure the coordinates of each point on the black paper, take the absolute value (accurate to one decimal place), and fill in the corresponding coordinate bar of the dialog box. Click “OK” to return to the previous interface.
4. Generate calibration files
Click “F6 保存参数到指定文件” to display the following dialog box. Please specify the file name for the file, otherwise the save will not be successful, such as “9 points“. Be sure to remember the file directory location.
5. Verify the correction accuracy
Click “F7 打开指定参数文件” to open the calibration file you just saved.
Replace the workbench photo paper and re-tilt it. Then click “F8 校验校正后的标准矩形“. At this time, the device will mark the following pattern. The standard pattern is a square shape fill with a fill pitch of 5mm.
The above figure clearly shows that there is a significant error in the coordinate value measured by coordinate 6. It needs to be recalibrated and return to step 4. If the pattern is correct overall, use a ruler or a tool with higher precision to measure whether the spacing of each line is 5mm, and measure horizontally and vertically. The corrected image measurement value should be as close as possible to 5mm. If the error is too large, please recalibrate. Note: This measurement error depends on the customer’s requirements and is usually within ±0.1mm. If it does not meet the customer’s requirements, please return to step 3 to re-correct, and vice versa.
6. Import correction file
After the calibration is completed, enter the EzCad2 software, click “F3 参数“, check the use of the calibration file, and click the arrow (as shown in the figure mark position) to import the calibration file saved in step 4.
Click “确定“, the calibration file has been loaded at this time, the galvanometer has been corrected, and normal marking processing can be performed.
