The Story

Since I got my first laser machine, I always wanted to engrave tumblers so I knew I needed a rotary attachment. But I soon discovered that my options were very limited.

These devices available were either super expensive, some selling close to $1K or, on the other extreme, cheap and poorly made. Those that were less expensive, had absolutely no indication of how they would work with my laser machine or how I would connect and configure them. There was zero instructions and zero communication with the manufacturer.

Frustrated, I set out to design a better rotary attachment that can engrave anything I throw at it, and will not break the bank. After much testing, tinkering and trial and error, I finally came up with a functional design that’s simple to operate, very durable, can be adopted to a wide range of objects, and is compatible with most laser engravers.

The Design

Designed from scratch by us at LensDigital, PiBurn utilizes a V-slot rail system, something that’s frequently found on 3D printers. V-rollers allow for effortless movement on both horizontal and vertical axes, allowing the rotary to fit a huge variety of objects. Wine glasses, tumblers, drumsticks, mugs, and much more can be securely installed on the rollers.

The integrated head clamp holds hollow objects in place, preventing slippage of heavier items. The clamp can be rotated out of way if needed, to accommodate bottles, for example.

Our stepper motor is the most expensive and critical part of the rotary attachment and we spent a lot of time testing various motors from several manufacturers. What we found was that the cheaper ones, while providing sufficient torque, may overheat to dangerous levels. For our final design, we use industrial, extra low heat steppers produced by Leadshine (a leader in motors for laser machines).

The final design is so flexible and versatile, it can support almost any size object, from large 30 oz. tumblers to thin champagne flutes. And the quality of components means the rotary can take a beating and serve you well on your biggest orders.

Compatibility and Support

Probably the most common question we hear is how will PiBurn work with my laser machine?

There’s not a single rotary attachment on the market that can guarantee you that it will work any laser engraver out there. Most Laser machine manufacturers will offer an attachment that works ONLY with their machine. The goal of PiBurn is to be compatible with as many machines as possible.

While we could not possible have access to every single laser engraver in the world we can say with confidence that it will work with most Ruida controller based machines. PiBurn has been tested with Boss Laser machines as well as so called “50 Watt Chinese Laser” array of machines. So, if you have a Boss Laser or something like the SH-G350 or “Red Sail” lasers, you are all set!

For everyone else, we are willing to work with you on identifying and customizing PiBurn rotary attachment to work with your laser engraver.

Available space inside your laser machine is something to keep in mind. If PiBurn cannot physically fit, it will obviously not work for you. Please make sure you have enough clearance between bottom of your bed and focal point of your laser. You will need about 4 inches plus diameter of your desired object like cup or tumbler.

Most important is that you need to know what kind of stepper motor is supported by your stepper driver, so we can ship you the correct one. It’s either a 2-phase or a 3-phase stepper. Boss Lasers for example use 3-phase steppers, and cheaper Chinese lasers use 2-phase. Please visit this guide that will help you to identify which motor your machine has.

A manual and user configuration guide will be provided as well. It will explain everything you need to know and how to setup PiBurn with your laser (i.e. things like circle pulses, diameter, etc.) as well as guide with useful settings for various engraving materials.
