Is the World Ready for a Vertical Laser? What’s the first thought that comes to mind when you hear the term laser engraver? Probably a large bulky machine resembling a refrigerator on its side. They are powerful, capable jacks of all trades and have given thousands of families and small businesses a way to make consistent revenues. At the same time, they are huge, difficult to transport, set up and operate. And, if you really think about it, engraving has been stuck in the same horizontal lane much too long. This is especially true for cylindrical engraving like tumblers, mugs, and bottles – or those items that were designed to stand upright not lay flat down. Makers have had to bend, twist, jig, tweak, dial in the rotary, and adjust steps, just to engrave a simple tumbler. Sure, the PiBurn rotaries make the process much easier, but what if it were easier still? What if engraving didn’t have to fight gravity? What if gravity actually helped? And what if the laser and the rotary were ONE DEVICE? VertiGo from LensDigital and OneLaser is the answer to these questions. It is the world’s first vertical laser and the first with a built-in rotary. No more complicated setups. Just place your cup, bottle, urn, or bucket upright, lock it in and let gravity and the laser do the rest. The PiBurn Grip2 powers the whole process with a self-centering jaw designs that eliminates all guess work. Makers spoke out. We Engineered. From hundreds of interviews with high-volume tumbler engravers (including those clearing $100K+ annually), we kept hearing the same pain points: Setting up a rotary takes too long each time. Taking the honeycomb and blades out breaks rhythm. Most lasers can’t handle oversized or weirdly shaped items. They do not fit. They do not want to be laying down. We invented VertiGo to fix all of that. Why It Works: 1. Gravity makes setup easier.VertiGo flips the game by going vertical. Instead of trying to secure something sideways, let the object stand upright naturally. Gravity does the stabilizing, the chuck jaw self-centers the object, and you get perfect alignment every time. Just push the button to engrave perfectly each time. 2. Built for fast, mobile, and high-margin workflows.At markets and events, the real money comes from on-the-spot engraving. It needs to be fast, clean, and portable. VertiGo was made for this. It sets up in minutes, fits on a countertop, and turns curious shoppers into customers in seconds. You do not need a chiller or water cooler as the 38 Watt RF tube is fan-cooled. 3. One machine, endless possibilities.Tumblers make up over 25% of most engravers’ income, but that’s just the start. VertiGo’s innovative design means you can engrave tall bottles, buckets, huge dog bowls, anything that stands up. No hacks or workarounds. Just plop it in, tighten the Grip and engrave. 4. No more fiddling with fixtures.For the first time, the rotary is not an add-on—it’s the heart of the machine. VertiGo combines PiBurn’s industry-leading Grip 2 rotary with OneLaser’s built-in autofocus and firmware tuned for rotary jobs. You get speed, simplicity, and reliability in one unit. 5. Smarter workflows are hereOur goal was to make VertiGo the easiest way to engrave anything that wants to stand upright. Makers who tried it became instant believers. There is only one problem with this machine. Once you engrave a tumbler upright, you’ll never want to fight gravity again. Built Different by Design with a Partnership that Makes Sense. VertiGo is the result of a deep collaboration between LensDigital, creators of the PiBurn, and ONELASER, a U.S.-based laser engineering firm that doesn’t outsource innovation. In fact, they helped design the product in the US. From the first sketch in 2022 to the production-ready prototype in 2025, we’ve made design decisions to improve the user experience for makers, not cut corners, because that’s how you build something truly new and valuable. The VertiGo Verdict Laser engraving is overdue for a new form factor. One that works with gravity, not against it. With VertiGo, gravity becomes your ally. Portability becomes another profit channel. And every tumbler becomes a canvas for your creative outlet, breaking down the barriers of complexity and confusion. You ready to go vertical?  VertiGo ™ — Engrave Upright.

One of the most common questions we receive from makers and engravers is: What’s the difference between a chuck laser rotary and a roller laser rotary attachment—and which one should you choose for your CO2 laser engraving machine? So, which laser rotary should you get? This is a critical question when selecting the best laser rotary solution for your engraving projects. Whether you’re working on tumblers, mugs, or other cylindrical items, understanding the subtle differences between these laser rotary attachments can help you achieve flawless results. Many professionals actually keep both types on hand to maximize versatility for engraving a wide range of objects. What Is a Laser Rotary Attachment? A laser rotary attachment is a specialized accessory for your CO2 laser machine. It rotates cylindrical objects—such as drinkware, tumblers, and even unconventional items like baseball bats—so the laser can engrave them line by line. Unlike flat-surface engraving, which uses two-axis movement, a laser rotary spins the object to enable precision engraving on curved surfaces. Both chuck and roller laser rotary attachments are designed to secure your object inside the laser, connecting to a dedicated rotary port or the Y-axis controller. The Chuck Laser Rotary Attachment The chuck laser rotary attachment (also known as the jaw chuck) uses a robust metal clamping system, similar to what you’d see on a drill, to firmly hold your cup or mug as it rotates. This attachment allows for versatile positioning of the jaws—either on the inside or outside of the object—to leave ample engraving space. Benefits of the Chuck Laser Rotary: Heavy-Duty Handling: Capable of managing heavier objects, especially when paired with a back support system. Precision Techniques: Ideal for advanced engraving techniques such as crosshatching and scoring, where the rotary moves back and forth. Versatility on Small Items: Works well with smaller objects, like pens, ensuring a secure hold. Reliable Stability: Prevents walking or slipping even when dealing with heavy handles. Flexible Clamping: Can grip objects from both the inside and outside, and even handle non-cylindrical items that a roller attachment might struggle with. High-Speed Framing: Allows for higher framing speeds since the object remains firmly in place. Drawbacks of the Chuck Laser Rotary: Tool Requirement: Needs an Allen wrench (chuck key) to adjust the jaws. Bulkiness: Its size may reduce clearance, particularly in smaller laser machines. Adjustment Hassles: Often requires multiple adjustments for uneven objects due to fixed jaw angles. Risk with Delicate Materials: The powerful jaws can damage fragile glass if over-tightened. Higher Cost: The specialized chuck jaw can be expensive, adding to the overall cost. Diameter Settings: Requires manual adjustments for different cup diameters, potentially slowing down your workflow. UPDATE: Our innovative PiBurn Grip2 has been designed to eliminate many of these drawbacks, providing a more efficient and user-friendly chuck laser rotary attachment for your CO2 laser machine.   The Roller Laser Rotary Attachment The roller laser rotary attachment operates on friction, using a motorized wheel to rotate the object. This attachment is highly popular for engraving tumblers, mugs, and wine glasses because of its simplicity and ease of use. However, achieving the right friction is essential—especially when engraving objects with unbalanced weight distribution, such as mugs with heavy handles. High-quality roller laser rotary systems, like our PiBurn V series, include an adjustable metal clamp to increase friction, ensuring that even challenging objects rotate perfectly during the engraving process. Benefits of the Roller Laser Rotary: Versatile Engraving: Perfect for a variety of drinkware—including cups, mugs, wine glasses, and tumblers with handles (when equipped with a clamp). Gentle on Materials: Minimizes the risk of damaging your delicate drinkware. User-Friendly: Fewer moving parts make it an excellent choice for beginners. Adjustable Setup: Premium models offer adjustable height settings, keeping your object level with the laser even on tapered surfaces. Consistent Performance: Once calibrated, you won’t need to change diameter settings for each new object. Compact Design: Its low-profile build allows you to work with larger objects, even on smaller laser machines. Quick Swaps: Efficiently swap objects to boost productivity in high-volume laser rotary engraving projects. Drawbacks of the Roller Laser Rotary: Speed Limitations: Relying on friction means you need to slow down during framing and acceleration to prevent slippage. Heavy Object Challenges: Extremely heavy or complex items can be tricky to manage. Seam Issues: Minor slips can result in seams on full-wrap designs. One-Way Rotation: The roller attachment typically rotates in one direction, making certain techniques like crosshatching unfeasible. Potential for Walking: Objects may shift horizontally, causing skewed designs. However, advanced models like the PiBurn include adjustable stoppers to counteract this issue. Choosing the Right Laser Rotary for Your Projects For those who want the best of both worlds, very few laser rotary attachments offer both chuck and roller systems in one unit. The PiBurn Omni, available at Lensdigital.com, is a powerful solution that integrates the advantages of both designs. Whether you’re engraving tumblers, mugs, or other cylindrical objects, understanding these laser rotary attachments’ unique features is key to optimizing your CO2 laser engraving machine. Use this guide to determine which attachment—chuck or roller—is best suited for your projects, and explore advanced options like the PiBurn series for a seamless engraving experience.

  The Yeti Chick: How Engraved Tumblers Bought an $83,000 Tesla Cybertruck   A year ago, nobody knew about the Yeti Chick. And now she runs the largest Yeti Marketplace on Facebook and is the engraver most people turn to for the best customized Yeti products in the world. AND she purchased a little battery-powered something just from her tumbler earnings this past December. How did she do that in just one year?!             Alexandra, aka The Yeti Chick, has built a thriving business out of customizing full-wrap Yeti tumblers and exceptional customer service. What's incredible is that she did this in just one year. She is married to Stan (that's me!) from LensDigital and often helps us beta-test brand our new PiBurn products. We have three beautiful boys and live in New Jersey.   She’s the driving force behind the boutique customization business mycup.io and leads a Facebook community (www.facebook.com/groups/bstmarket/) of 90,000 members. But her story goes far beyond the numbers—this mom of three boys once worked in the corporate world as an actuary at MetLife and Pacific Life before deciding to focus on family and her creative energy. Now she’s turning her passion for the art of laser engraving into a profitable enterprise, all while sharing her knowledge with fellow makers.   How did she start this business?     By the Numbers: $18 Profit Per Tumbler Add up to Cybertruck in Eight Months of Hustle   When you do the math, it’s pretty mind-blowing. Alexandra charges, on average, $18 of profit per full-wrap engraved tumbler. It took roughly 4,611 of these tumblers to reach the $83,000 needed for her brand-new Tesla Cybertruck (83,000 ÷ 18 ≈ 4,611). She did this over eight months in 2024, including the Holiday Season, which was big for her. That’s a lot of Yetis - around 575 full wraps each month, or 20 per day. It's a huge testament to her dedication, hustle, and customer service. Took two more months for taxes ;)   Sometimes she engraves larger, more unique items like the Yeti Beverage Bucket. She often charges double the price of retail for those unique items. While these items are very profitable, they do not command the same volume and demand as the standard 20, 30oz tumblers. Also, a bucket is tricky to get right. A full wrap that does not meet perfect at the ends will not go out to customer. Instead it will be either auctioned off at a discount or given away to a friend, or husband who could really use one (hint hint).         This incredible full-wrap Yeti Bucket is only possible on the PiBurn Grip2 with the double extender jaws. It takes almost two hours to run at 300mm/sec.   But it's worth it. This item will sell for about double price of retail:     From Actuary to Engraver Extraordinaire   Before she was The Yeti Chick, Alexandra spent her days crunching numbers in the insurance industry. She worked as an actuary at MetLife and Pacific Life, a role that demanded precision and analytical thinking. Though the corporate career was stable and lucrative, it left little room for family time and creative freedom. Ultimately, she decided to pivot to a lifestyle that allowed her to be more present for her three boys—and she hasn’t looked back since.   How to Approach Customer Service.   When I asked her about her order flow and how she thinks about customer service, this is what she shared:         The PiBurn Grip2 Advantage   A major part of Alexandra’s success lies in the tools she uses—specifically, the PiBurn Grip2 rotary attachment. LensDigital has relied on Alexandra to Beta-test the Grip 2 and provide feedback on possible improvements. The rotary proved reliable and its user-friendly design lets her engrave tumblers quickly and consistently. If you’ve followed our PiBurner of the Week blog series, you’ll know the PiBurn has been essential for many entrepreneurs looking to scale their custom engraving operations.   Building a Supportive Community   Alexandra doesn’t keep her methods to herself. She actively shares tips, tricks, and tutorials with other makers in the community. Whether it’s a first-time engraver wondering if expensive tumblers are worth the risk, or a seasoned pro looking to streamline their process, Alexandra offers guidance with an open heart. It’s this generosity that helps her community thrive—and it’s one reason she’s so admired in the laser engraving community. She even welcomes other engravers to share in her HUGE market - the demand for tumblers is too great for any one engraver to handle. So, other makers and engravers are welcome to participate through her online marketplace - EverCrafter.shop.       A Lifestyle of Family, Creativity, and Freedom   One of the biggest draws to this business model for Alexandra is time. She gets to spend more of it with her three boys—something her former corporate career didn’t allow as much. Now, she can create, earn an income, and be a present mom all at once. The Tesla Cybertruck purchase is just icing on the cake—proof that a passionate side hustle can become a life-changing venture.   What’s Next for The Yeti Chick?   With the Cybertruck acquired, Alexandra’s looking ahead to even bigger possibilities. But for now, she is taking our youngest on a road trip down to Disney World! (Also fully financed by her engraved cups!) Check out her shop at mycup.io and on Etsy.   If you need help getting started or have any questions on the PiBurn and the tricks she has learned, reach out to her at mycupengraving@gmail.com, or find her on the PiBurn Labs group on Facebook.      

    What is the bottle effect?   When using a laser engraver, one common issue you might encounter with a roller rotary is the "bottle effect."   This occurs when you place a bottle with a narrow neck and wide body onto the rotary.   If you position the narrow neck on the roller wheels, the engraving on the wider body may come out stretched. This happens because the laser doesn't account for the difference in the distance traveled by the narrow and wide parts.   How do you fix the bottle effect?   To fix this, simply turn the bottle around and place the wider body on the roller wheels. You can also use the Mega Clamp to help increase the friction if you need to do a full wrap and can't have any slipping.     The setup pictured will eliminate the bottle effect and reduce any slipping to a minimum. Make sure to use the stoppers on your PiBurn!   What else can you do?   It's important to note that the bottle effect only impacts roller rotaries. With chuck rotaries, the neck diameter isn't a concern—only the diameter of the body matters, making them a better choice for objects with varying diameters.     If you are setting up the same bottle on the Grip or Grip 2, you only need to measure the diameter of the body, not the neck. There will be no bottle effect on the Grip or any other chuck rotary.   How about something crazy like this Jug?     Still, no bottle effect on the Grip2. Just measure the wide body diameter and you're good to go.

Ever had a tough time getting that perfect design on your tumbler? You're not alone. Many folks struggle with it, but there's an easier way—use a high quality roller rotary.   Higher quality roller rotary systems can help you get those designs just right. They spin the tumbler as the laser machines engraves, making sure every part of the tumbler gets engraved evenly.   In this blog post, we'll show you how to set up and use a roller rotary system for tumblers. We’ll also tackle common problems. Ready to learn more?   Key Takeaways   Roller rotary engraving helps you get even designs on tumblers by rolling them as they engrave. Adjust the roller diameter and set steps per rotation to make sure your tumbler fits snugly and engraves accurately. Use the right laser power and speed to avoid poor quality engravings and errors. Testing on simple straight and cheap tumblers. Using painters tape at 10% power helps find the perfect settings. Position your tumbler evenly before starting, and always frame to check the engraving area. Different tumbler sizes can change how designs look. Adjust rollers and steps per rotation for each size.   Preparing Your Tumbler for Engraving   First, you need to get your tumbler ready for engraving. This means adjusting the roller and setting the steps per rotation... it’s easier than it sounds!   Adjusting the Roller Diameter   Adjusting the roller diameter is key. This step ensures your tumbler sits snugly on the engraver. Measure the circumference of your tumbler first. Use this number to set the correct roller size.   It helps avoid wobbles and keeps your engraving clean.   Never underestimate a good fit! A stable tumbler means sharp designs every time.   Check if rollers are adjusted for different sizes too. Not all tumblers are equal in width and shape. So, tweak as needed to match each one perfectly... less guesswork, more precision!   Setting Steps per Rotation   Get the steps per rotation right for a good engraving. First, find your tumbler's circumference. Measure it with a tape measure or calipers. Then check your roller's diameter. PiBurn wheels are 63mm. Now run the 100mm test to dial in your steps. You can use this alignment tumbler to make things really easy. Make sure to check the manual for suggested starting steps.   Set these values in your laser software next. Each machine might differ, so check the manual. This ensures smooth and accurate engraving on any tumbler size. If you get everything right here, you'll avoid many common errors later!   Selecting the Right Laser for Tumbler Engraving   Choosing the right laser for your tumbler is key. Consider power and speed to get the best results.   Considerations for Power and Speed   Different tumblers need different laser settings. The power of the laser affects how deep it cuts. Higher power burns deeper but can also damage your tumbler. Aim for a balance to get good results.   Speed is just as important! A slower speed gives the laser more time to cut, which means deeper engraving. But too slow and you risk overheating... and no one wants a melted tumbler! Test small areas first to find what works best.   Too much power can ruin your design, while the right speed brings it to life.   Step-by-Step Guide to Engraving a Tumbler   4. Step-by-Step Guide to Engraving a Tumbler: Get ready to learn how to position your tumbler, and start the engraving process, with some simple steps—let's make this fun!   Positioning the Tumbler   First, place the tumbler on the roller rotary device. Align it so that it sits evenly. Check for any tilting or wobbling. Use the right clamps to hold it steady. Make sure the tumbler's circumference is centered.   Next, adjust the rollers so they fit snugly against the tumbler. Turn on your laser engraver at low speed first to see if it's stable... no one wants a rolling mess! That’s about it—time to move on and start engraving!   Running the Engraving Process   With the tumbler in position, start the engraving process. Make sure your laser settings are right for your tumbler's material. Use a test run on a scrap piece to check these settings.   Click “Start” on your machine’s software and watch it engrave. Keep an eye on it to ensure it's running smoothly. The rotary roller will spin the tumbler as the laser etches your design all around.   Troubleshooting Common Issues   5. Troubleshooting Common Issues: Sometimes, the tumbler might not fit right or the design looks off… read on to solve these common problems!   Proportion Issues with Different Tumbler Sizes   Different tumbler sizes can mess up engraving proportions. The size of the tumbler’s circumference affects how your design wraps around it. Bigger tumblers need adjustments in the roller diameter to keep the design looking right.   Smaller tumblers might make text look squished or stretched. Adjusting steps per rotation helps a lot with this issue. Always test on a blank before starting on your final piece.   Conclusion   So, that's how you engrave a tumbler using a roller rotary! It's not too hard, right? Just set your tools and follow the steps. If things go wrong, check for common issues. Happy engraving!   FAQs   1. What does it mean to engrave a tumbler with a roller rotary?   Engraving a tumbler with a roller rotary means using a special machine that rotates the tumbler while engraving its surface. This ensures even and precise designs around the entire circumference.   2. How do I measure the circumference of my tumbler for engraving?   To measure the circumference, use a flexible tape measure and wrap it around your tumbler at its widest point. This measurement helps in setting up your roller rotary engraver correctly.   3. Can any type of tumbler be engraved using this method?   Most tumblers can be engraved as long as they fit within the size limits of your roller rotary engraver and have an even surface along their circumference.   4. Is it hard to learn how to use a roller rotary engraver for tumblers?   Not really! With some practice, you can get the hang of it quickly. Start by following simple steps from guides or tutorials, and soon you'll be creating amazing designs on your tumblers' surfaces.
