Back with Frickin' Laser Beams!

I am back. And now I have a laser. 

I purchased the Creality Falcon2 22-watt laser with all of the trimmings. I have used a laser in the past, however, that machine was very next-level and way out of my price point. If you have the means, the Epilog series of lasers are amazing. I do not have the means but I set one up for the Buffalo Science Museum in 2013. 

I have dreamed of having my own machine and the Falcon2 was at my price point. 

Delivery was super quick and set up was "easy". I've had this machine for nearly two weeks and thanks to the Crowdstrike issue nuking every computer at work, I didn't get to unbox the Falcon2 for 12 days after delivery. 

I wanted to do an unboxing video, but I was too excited to film it and unboxing videos are not a habit I want to start. I will say the packing is excellent for both shipping and unboxing. They really thought out the consumer angle of this product. 

Setting up the laser is simple, but I would like to share some tips based on my background experience. These tips will draw on my time at Mattel/Fisher-Price and my experience with the Epilog laser. 

First, the Falcon2 has 60% of the power of the Epilog 35-watt system. This means the Falcon2 has less power needs and fewer protective systems. The Epilog is in a massive metal and glass box with specific venting methods set right into the frame. 

The Falcon2 only needs a tent with a fan to separate you from the laser. Additionally, the Falcon2 requires protective glasses despite having a plastic window on the tent AND a shield around the laser. Seriously, you only have two eyes so 3 layers of protection is good. 

Let's start with two issues I had with the tent. The tent sits on a plastic frame. The frame parts appear to be 3d printed plastic. It does require a bit of care assembling. Me and my hulk hands snapped one of the support tubes. 

This was laziness on my part. I could have used a little care or a dot of soap. 

The second issue I had was with the fan assembly for the tent. It comes with a fan shield.

PUT IT ON! 

Fans are devices with spinning blades. Despite everything Star Wars has taught me, they usually have covers. This prevents items like Jedi from jumping through them to destroy your Imperial Plans. 

It is a little-known fact that if you stick your fingers into a tiny fan to see if it is sucking or blowing, the blades always SUCK! 

In addition to the Falcon2 laser, I also purchased a very nice set of bandaids. If I had put the shield on the fan from the start, I could have saved a couple of bucks on bandaids.

Live and learn. 

Now we are to the third issue I had with this product. On my first try, the laser didn't work. It wouldn't even move. This indicates a firmware update is necessary. The process is pretty well documented, you simply load the file on to the provided SD card and stick the card in the SD card slot. This updates the main driver motors. 

Next, you load the laser head file on to the SD card and plug that into the laser head unit using the provided SD to USB-C connectors. It's odd, but it works. 

Having completed the update, the laser head moved and the air assist worked. But the laser would not fire. This one flummoxed me. I reached out to support to get help.  

They were ridiculously fast. I emailed at 9:45 pm and they responded by 5:00 am the next day. I was taken aback by the speed and the comprehensive support. They had me disassemble the laser head and check the internal connectors. This would have been daunting, but for the fact they provided all of the tools necessary to perform this check. They provided tools! 

Sadly, this was not my problem. 

Let's back up a bit and go to the same problem I always have... me. Remember how excited I was to assemble the product? I disassembled the whole thing and started over. This was not that hard. 

Before I go any further, I would like to explain the symptoms as they presented. 

Symptom One: the laser head and arm wouldn't move until I updated the firmware. Also, all of the lights blinked oddly. This was the red herring. After the update, the head and arm would move correctly including home and frame, and all of the lights gave correct/ready indicators including the laser, but the laser would not fire. 

On reassembly, I noticed something was off. There connector box on top of the arm for the laser head. When I pushed the connector in, it felt squishy. It also has a locking tab that would not lock. I couldn't see anything wrong until I used my camera.

In my haste, I bent a pin. It wasn't all that hard to push the pin back into place. I first tried the provided tweezers. That didn't work, they were a smidge too big. 

The next tool I reached for was an X-acto blade. It seemed like it would work, but I had just slashed my finger open on the fan so I put that down. What did do the trick was a clay sculpting tool. It has no sharp edges. 

I pushed the connector in and got the same squish. I thought I was being ham-handed again. Considering I already broke one part and stuck my finger into a spinning fan, this was highly probable.  

I fixed the pin again and took a better look at the problem. 

There are three cable management clips on the arm and the third leaves barely room to push the connector into the plug. Remember I mentioned they sent tools with the laser? 

One was an Allen wrench, the right size to remove the cable management clips. With that one clip removed, the connector was easy to fit, click and all. 

The last step was to put the clip back. I gave myself a lot of slack by homing the laser head and pulling the lines out of the way. The clip went back home and I had good cable management again. 

My Mattel/Fisher-Price training tells me they could have put this in the instructions but this isn't the typical consumer product. It's not like you are expecting a child to survive first contact with the beam.  

Since I was in troubleshooting mode, I simplified testing by loading one of the sample images to the SD card and disconnecting the laser from my computer. One problem at a time, right? 

I was immediately rewarded with the air assist powering up, the laser head homing and framing, and a brilliant blast of light. 

Within a few minutes, I had my first engraving. 

The image to the left shows the final product, not the process. You need to have all of that safety gear in place to use the laser. 

Like so: 

And so: 

And, also so: 

Ok. The smoke and CO detector was not actually provided with the device and is more of a nod to the fire that burned my house down once before. 

While you can read that as humor, it isn't. With the tent and fan in place and one window open, you can run this thing in your home without terrible odor problems. Even if your home includes 3 survivors of a fire who are sensitive to burning smells. So long as you have good ventilation. I would also like to point out the laser doesn't trigger a smoke detector 10 feet away in the same room. 

I suspect when I goof, it will trigger the detector, but I'll have to try harder to do that. Also, the product does have a built-in fire detector, so I'll have to try real hard. 

I polled four people on the smell and got some surprising reactions. 

Me, the guy who was not at home for the fire: It smelled alarming bad, like I was going to send my family into PTSD mode. 

Nathan, the kid who was outside but present for the fire: "The laser smells like smoke."

Catherine, the girl who got out last: "It smells like incense."

Kitty, my wife, ran back into the fire to save the cat and collapsed from smoke inhalation: "I can't smell anything." 

So, it does clearly smell funny but not that bad. 

I'd like to close with a final image, an improperly run speed vs power test. 

I cannot wait to get the hang of this and start making products.
