If there is an error of more than 1mm when you use the fine distance measurement function (close-range camera) around the center of the working area, you can recalibrate it according to this guide.
Things you need: A Windows computer and the calibration tool for IR distance measurement. You can get the tool from customer support (


Calibration Steps

1. Download the calibration software.


2. Put all the slats in position. Make sure they are seated properly, otherwise, the calibration may not be accurate. Remove the drawer and put it right underneath the machine.

3. Connect the machine to the computer with a USB cable.


4. Decompress the zip file and run the software. In the software screen, click on the 'Connect' and the 'Clear data' button.


5. Open the lid of the machine, then click on the 'Red spot on' button in the software.


6. Assemble the calibration tool. There are 5 horizontal surfaces on the tool each representing a level of height. Put the tool between two slats as shown in the photo below. Make sure the red spot falls on the -21mm surface.

7. Close the lid of the machine. Click on the 'Red spot on' button again, and then the 'Auto capture' button. The laser module will move to the other four surfaces for measurement.


8. After the laser module measures all the surfaces, click on 'Generate calibration file'. You should see a graph and a pop-up window that says 'Generating the calibration file succeeded!' If it failed, please check if the slats are completely seated in position, and if the drawer is placed underneath the machine.


9. Click on the 'Distance measure verification' button to see if it works. If not, please repeat the above steps. If yes, please move on to the next step.


10. Upload the calibration file. And the calibration process is all done.
