3. Setup
The WAINLUX MD1920 is designed for quick and easy setup, featuring a plug-and-play modular design. Follow these steps to integrate it with your compatible laser engraver:
- Placement: Position the main rotary unit and the adjustable support unit within the engraving area of your laser engraver. Ensure they are aligned to securely hold the cylindrical object.
- Connection: Connect the USB cable from the main rotary unit to the designated port on your WAINLUX K10 or X1 laser engraver.
- Object Loading: Carefully place the cylindrical object (e.g., wine glass, tumbler) onto the rollers of the main rotary unit and adjust the support unit to firmly hold the other end. Ensure the object is level and stable.
- Height Adjustment (if necessary): For optimal engraving, you may need to adjust the height of your laser engraver or the rotary attachment itself. The K10 engraver can be raised to accommodate the rotary setup.
- Software Configuration: Refer to your laser engraver's software manual for specific settings related to rotary engraving. This typically involves enabling rotary mode and inputting the object's diameter.
