Why Use a Rotary Attachment?

Before we get into the nitty-gritty, let's discuss why a rotary attachment is crucial for this project. Yeti tumblers have a cylindrical shape, which presents a challenge for standard flat-bed laser engravers. A rotary attachment solves this problem by rotating the tumbler as the laser works, ensuring even and precise engraving around the entire surface.

The rotary attachment is essential because it:

• Allows for 360-degree engraving
• Maintains consistent focus and power across the curved surface
• Prevents distortion of your design
• Enables you to engrave various cylindrical objects

A rotary paired with the right laser engraver makes tumbler laser engraving simple and easy. Optimize your Yeti laser engravings with a suitable rotary attachment for your laser engraver. 

Which Laser Engraver For Yeti Tumblers? 

You can use both CO2 and fiber laser engravers for tumblers. CO2 lasers are able to mark on coated metal, whether you’re applying a special laser marking spray or utilizing a painted stainless steel tumbler. Fiber lasers, on the other hand, engrave uncoated metals directly. They also offer the advantage of faster engraving times and the ability to work on both power-coated and uncoated stainless steel tumblers. 

When selecting a laser engraver, it's also important to consider software compatibility. Many engravers come with their own proprietary software, but you may prefer to use popular design programs, which offer more advanced design capabilities. Ensure that the engraver you choose can easily integrate with your preferred software, allowing for a smoother workflow and more creative freedom. Additionally, look for machines that provide user-friendly interfaces and comprehensive customer support, as these features can significantly enhance your engraving experience, especially as a beginner.

How to Laser Engrave Yetis

Now that we’ve discussed the importance of rotary attachments and finding the right laser engraver for your tumbler engravings, it’s time to get started! 

Step 1: Gather Your Materials and Equipment

Before you begin, make sure you have the following:

• Laser engraver with rotary attachment
• Yeti tumbler (or any stainless steel tumbler)
• Laser-safe cleaning solution
• Microfiber cloth
• Masking tape
• Design software (e.g., LightBurn, CorelDRAW)
• Safety gear (protective eyewear, gloves)

Step 2: Prepare Your Workspace

Safety first! Ensure your workspace is well-ventilated and free from flammable materials. Put on your protective eyewear and gloves. Set up your laser engraver in a clean, dry area with a stable power source.

Step 3: Clean the Yeti Tumbler

Thoroughly clean the surface of your Yeti tumbler using a laser-safe cleaning solution and a microfiber cloth. This step is crucial for achieving the best engraving results. Any dirt, oils, or residue can affect the quality of your engraving.

Step 4: Set Up the Rotary Attachment

Now, it's time to set up your rotary attachment. This process may vary slightly depending on your specific laser engraver model, but here are the general steps:

• Lower the workbed of your laser engraver to make room for your rotary. You may have to remove the bed entirely, depending on your machine. 
• Place your rotary on the honeycomb workbed.
• Plug the rotary attachment into your laser engraver according to your machine's instructions.
• Connect the rotary attachment to the laser engraver's control board.

Once you’ve connected your rotary to your laser machine, open up LightBurn or your chosen software on your computer. 

• Go to Tools and select Rotary Setup. Choose the type of rotary you have, and turn on Enable Rotary. 
• For the settings, start at 3000 steps per rotation and 2.5 in. for roller diameter. 
• Click OK, and you’re ready to start prepping your design.

Step 5: Secure the Tumbler in the Rotary Attachment

Carefully place your Yeti tumbler in the rotary attachment. Most attachments have adjustable roller wheels to accommodate different tumbler sizes. Ensure that the tumbler is centered and sits snugly between the wheels. The tumbler should rotate smoothly without any wobbling.

Pro Tip: Use masking tape to mark the area you want to engrave. This will help you align your design correctly and protect the surrounding surface from potential scratches.

Step 6: Prepare Your Design

Using your preferred design software, create or import the image or text you want to engrave on the tumbler. Keep in mind the following tips:

• Use vector graphics for the sharpest results.
• Consider the tumbler's curvature when designing—text or images may appear distorted if not properly adjusted.
• Keep your design simple for your first attempts.
• Adjust the design size to fit the tumbler's engravable area.

Step 7: Configure Laser Settings

Proper laser settings are crucial for achieving the best results on stainless steel. While exact settings will vary depending on your specific laser engraver, we utilized a 60W OMTech CO2 laser engraver with these settings: 

• Power: 30%
• Speed: 300 mm/s
• DPI: 390
• Passes: 1 (depending on desired depth)

It's always a good idea to test your settings on a scrap piece of similar material before engraving your Yeti tumbler.

Step 8: Focus the Laser

Proper focusing is essential for crisp, clear engravings. Most modern laser engravers have an auto-focus feature, but if yours doesn't, you'll need to manually focus the laser. 

• Move the laser head to the center of the tumbler.
• Use the focus tool provided with your laser engraver to set the correct distance between the laser head and the tumbler surface.
• Fine-tune the focus by making small adjustments and running test engravings on scrap material.

Step 9: Perform a Test Run

Before engraving your final design, it's wise to do a test run. Use the "Frame" or "Boundary" function in your laser software to trace the outline of your design without actually engraving. This step ensures that your design is properly aligned and fits within the desired area on the tumbler.

Step 10: Start Engraving

Now for the exciting part – it's time to engrave! Here's what to do:

• Double-check all your settings and alignments.
• Close the laser engraver's lid.
• Start the engraving process through your software.
• Monitor the process closely, but do not open the lid while the laser is operating.

Step 11: Post-Engraving Care

Once the engraving is complete:

• Allow the tumbler to cool before handling.
• Gently clean the engraved area with a damp microfiber cloth to remove any debris.
• If desired, apply a food-safe sealant to protect the engraving.

Congratulations! You've successfully engraved your Yeti tumbler using a CO2 laser engraver and rotary attachment.
