Why I chose the PiBurn 4.0
I usually just choose quality. But that isn't just the reason I chose the PiBurn 4.0 in this instance.
Taking a slightly different approach to my blog today, I wanted to just let you know that I am not an expert. That their are people out there that know more than me and that crush me in sales.
What I do know, is that some items don’t work, some work well, and some are designed so perfectly that if something goes wrong… It was your fault.
The latter, ladies and gentlemen, is the Pi Burn 4.0.
The 4 Wheel Rotary Axis
Why I ditched my 4 Wheel.
When I started in Laser Etching/Engraving, I knew at some point that my wife would want an engraved cup so I went ahead and packaged the 4 Wheel Rotary Axis with my laser. It was not a big goal of mine, but it was there. Eventually I got to it through customers requests and sales packages.
What I can say about the 4 Wheel is that it is very sturdy and honestly pretty well made. The connections are good, as well as the rubber o-rings. From the very beginning I saw a major flaw.
It’s simple. When you figure in the cost of a Yeti (or similar) cup, a mistake or error means real money. Mis-cut a piece of ply and you are out pennies, do that with a large Yeti and it’s $$$.
- It has no longitudinal (up and down) holding device
- It has no upward (lifting up) holding device.
The first means is that if your cup rolls forward or backward while lasing, your design WILL be flawed. Thus, trash. The same goes for the upward movement. I have noticed that at some “perfect” speeds when you are a different cup, occasionally albeit rarely, they jump. If it jumps, again, garbage.
The solution. PiBurn 4.0
The PiBurn 4.0 by Lens Digital LLC is specifically designed to target these problem. If I was their marketing team I would have a slogan like, “perfect, every time.” The PiBurn 4.0 comes with the following features that fix all issues I experienced:
- Front-End Stop. This is designed to have the cup pushed forward so that it has a natural stopping point that keeps it in place. It does this with a roller so your cup isn’t grinding on a metal bar and works in conjunction with the
- Clamp. Not the most ingenious name… but it works. The clamp both holds the cup down AND pulls it up to the front-end stop. The combination of these two items in my opinion solve the cup disaster scenario.
Everything shown in this article was made on an Omtech MF 2028 60 watt CO2 Laser. Interested in learning more about CO2 Lasers, this is an article from my blog about them.
Does the PiBurn 4.0 work? Yes!
I have laser etched somewhere around two hundred cups of different sizes since switching to the PiBurn 4.0 and all I can say is “wow,” because from the mechanical side of the etching, they are perfect every time. Zero movement. Just, exactly what you program every time.
Of course that is not to say that mistakes are not made. There is a lot that goes into calculating the circumference, steps per revolution and image design, but those are all on you. If YOU make the mistake you will learn from it and never do it again.
With the 4 Wheel Rotary Axis the mistakes were random and very hard to actually improve on. I will say, that their are kits you can buy for that device that will “mostly” fix their flaws. An example is this one from Etsy. But you have to modify your device.
One more feature worth mentioning but not pictured is the adjustable roller in the back of the cup. This roller is just one more failsafe that keeps your cup from coming off of the rotary. I personally think that PiBurn has thought of it all with this product. Truly above standard.
And if that wasn’t enough for you. LensDigital LLC, is out of Old Bridge, New Jersey. They design, assemble, test and ship from the good ol’ USA. Some components come from vendors around the world, but that is close enough to “Made in America” for me!
