Step 2. Securing materials with Rotary Extension

  • Press the "Lock Button" (highlighted as part 1 by the red arrow in the diagram) to secure the "Rotary Head chuck", avoiding rotation.

  • Rotate the "Chuck Gear" (highlighted as part 3 in the diagram) to adjust the grip diameter.

  • Upon securing the material, release the "Lock Button".

Note: Once the material is secured, release the Lock Button to enable rotation of the Rotary Head chuck during preview. Failure to do so will impact subsequent engraving.

Step 3. Activating Rotary Extension in Mobile Application

Please ensure the accessory and main unit are powered on before activating the Rotary Extension for normal use.

If you activate the Rotary Extension in the Setting before powering it on, it will not work normally. Please restart the mobile application and connect the Rotary Extension to the power supply. Here are two signs to check if your machine is properly connected to the rotary extension

Sign 1: Successful LP4 Bluetooth connection is indicated by a solid blue light.

Once you power on both the Rotary Extension and main unit, the former's indicator light will turn blue, confirming its power status.


Sign 2: Two beeps from the machine

Activate the Rotary Extension in the Setting interface of the mobile application. You will then hear two beeps from the machine. Please check the operations in the diagram below.

  1. Click "Preview" in the top right corner of the Creation interface.

  2. Click “Preview” in Rotary Extension Mode, and input the perimeter or diameter (in mm or inch) of the object.

Tip: Incorrect or void values of diameter/perimeter may cause engraving deformation or overlap.

Please note that millimeter or inch is the unit of length in mobile application. You can click “Settings” in the bottom toolbar of the Creation Interface and swipe left to switch from inch to millimeter.

During Preview

During the preview in Rotary Extension Mode, a straight blue beam will be emitted to the object to be engraved, indicating the image's X-axis width in the mobile application: X:83.36mm.

The Rotary Head chuck will rotate after clicking “Continue”, and rotation path corresponds to the image's Y-axis height: Y:79.14mm.

Release the Lock Button before starting previewing. Otherwise, the Rotary Head chuck is unable to rotate. If the Rotary Extension doesn’t work properly, please check if there is any misoperation in step 1 and 3.
