1. Set up the laser rotary attachment: Connect the rotary axis to the laser engraving or cutting machine and secure it in place. Then, place the object you want to engrave onto the roller and adjust the roller to fit objects of different sizes. Tip: Do not tighten the drum too tightly when rotating, as it may slip.
   
2. Prepare the design: Use laser engraving or cutting software to prepare the design to be engraved on the cylindrical object, ensuring that the design or pattern is adjusted to fit the object’s circumference. Note that there will be some deviation between the starting and ending points after one rotation, making it difficult to perfectly align them. It is not recommended to design a pattern that fits the exact circumference.
   
3. Adjust settings: 4400 steps per rotation is a good benchmark. Your roller diameter may vary depending on the model, so be sure to measure and input the correct value. Adjust the laser settings, such as power, speed, and focus, to match the material and thickness of the cylindrical object. Tip: Use USER ORIGIN together with the rotation, not the current position or absolute coordinates.
   
4. Start the laser and rotary attachment: Activate the laser and rotary device, then begin the engraving or cutting process. Monitor the process to ensure that the laser accurately engraves or cuts around the object’s pattern.
   
5. Complete the work: After the engraving or cutting is complete, turn off the laser and rotary attachment. Remove the cylindrical object from the roller and inspect the finished product.
