¶ 1. Symptoms
When using the Photo Positioning feature, if the real-world image displayed on the canvas does not fully match the actual position of the material, you may observe one or more of the following:
-
The live image on the canvas appears slightly shifted vertically or horizontally
-
Material edges appear overlapped or misaligned in the image
-
The crosshair position shown on the canvas does not correspond to the actual position on the material
-
The design appears correctly aligned with the material in the software, but the actual processing result is offset
These observations typically indicate that the captured image is not fully aligned with the device’s internal coordinate system, which can affect the accuracy of photo positioning.
¶ 2. How to Troubleshoot
¶ 2.1 Ensure the Material is Placed Flat
- Please make sure:
- The material is not warped or lifted
- The honeycomb tray or base plate is properly seated and flat
- If the material is thick, or you recently switched to material with a different thickness, the camera image may become visually inaccurate (similar to how your eyes see objects differently at various distances)
Inconsistent material height can also cause slight distortion.
¶ 2.2 Re-measure Material Height Using “Select Point Measurement”

Steps:
- In Aliencell Space, click the Measure
icon and select [Measure by select point] from the dropdown menu. The cursor will turn into a red crosshair within the canvas. - Move the red crosshair to a location on the material surface and click to confirm. The device will automatically detect the precise height of that point and calibrate the camera view.
- In Aliencell Space, click the Measure
¶ 2.3 Take a New Photo
Sometimes lighting or angle can momentarily affect the capture. Retaking the photo often resolves minor distortions.
¶ 2.4 Perform Photo Capture Calibration
If you carefully completed Step 2 but the image still shows noticeable offset or misalignment, the camera’s physical position may have shifted slightly from its original factory alignment. In this case, perform a full calibration on the machine’s touchscreen.
¶ Why this step is needed
The camera is mounted on the machine’s lid. Frequent opening/closing or vibration during transport can cause the camera to shift by a fraction of a millimeter.
Even this tiny displacement is enough to cause visible misalignment.The calibration process lets the camera “look at” the six alignment markers on the bottom plate again and re-establish its correct reference position.
¶ Steps:
-
Clear the work area:
Remove all materials so the six circular calibration markers on the bottom plate are fully visible and unobstructed.
-
Open the Maintenance Menu:
On the touchscreen home page, tap Setting > Maintenance. -
Start the Calibration Program:
Tap Photo Capture Calibration.
-
Begin Calibration:
When prompted, make sure the bottom markers are not blocked, then tap Start Calibration. -
The system will automatically:
-
Home — The laser module moves to a predefined location to clear the camera’s view
-
Capture images — The camera photographs all six calibration markers
-
Correct coordinates — The system recalculates and updates the camera alignment parameters
-
-
Finish:
After the screen shows a success message, exit the menu.
Your next camera capture will use the newly calibrated parameters.
