When you use the jig processing, the ArUco codes are engraved directly onto the jig during processing. The ArUco codes contains coordinate data that helps you position the jig. Before processing, the software must calibrate the ArUco codes on the jig, as shown in the figure below.

If, after calibration, the xTool Studio software displays a pop-up window with the error code "ArUco Code Detection Failed" (Error Code -504), please refer to the article for troubleshooting.
