Carverall K15 Pro Laser Engraver Review – Great Budget Laser

Over the last few years I’ve tried to identify “The Best Budget Laser”. Typically, my definition of that is around a $300 machine. The Carverall K15 Pro comes in at just over $300 with a safety shield. It can however be configured without one. No shield and you can add on a 12 watt laser module for around $200. That my friends is a bargain.

The machine Carverall provided me to review came in the following configuration:

• Safety Shield
• 7 watt laser module
• US Plug

This build comes in at around $328 which is a good price for a machine of this size/power/safety configuration.

Build Time

I took a video of the build, or at least I thought I did. The camera died during the process. I did however check how long it took to build just the laser. Only 12 minutes.

The safety enclosure took me around 20 minutes as those acrylic shields typically are coated with protective films. Additionally, there are lots of screws and a little head scratching involved when reading the instructions. The instructions are good, but there is always that feeling of “Am I doing this right?” involved.

There was one gotcha during the safety enclosure build. When I put it all together I noticed that the access door wasn’t hitting the safety micro switch on the machine. When I started visually inspecting why I noticed there was an area that seemed to be missing something on both sides.

I reviewed some photos I had taken earlier and saw these magnetic pieces on the enclosure portion. The access door swings down and the magnets on it snap to these pieces which are now missing.

What I THINK happened is that when I ripped the protective film from the acrylic those pieces went flying. The reason I think that is that I found both of them in my deep pile carpet nowhere near where I was assembling the K15 Pro.

Once I located them I reattached them with a drop of super glue. All is well and perfect again. I notified Carverall and they were appreciative of the feedback and seemed to have been aware of some instances where they had shaken loose during shipment. I discuss this in the video below.

THIS IS WHY MANUFACTURERS HAVE BETA TESTERS AND REVIEWERS

Not just to get the good word out but to get feedback from experienced users.

7 Watts?

In a world of 60 watt diode lasers now 7 watts seems dated. Let me tell you this. It is not. 95% of the stuff I do with a diode laser can be done on a FIVE WATT LASER. And in fact I do some stuff on a 3.5 watt laser sometimes.

Features And Software

The Carverall K15 Pro has a working area of X=200mm, and Y=300mm. An optional rotary may be added. Additionally, the safety enclosure has a cut out to add an overhead camera. Cool!

The K15 Pro works with LaserGRBL, Lightburn, and CutLabX which has an app available for Android or IOS.

CutLabX looks pretty basic but it is free whereas the best laser engraver software in the world, Lightburn, is not. And you have to consider that the Carverall K15 Pro is a budget machine and most likely will be used by a first time laser engraver hobbyist or as a backup machine.

I allowed Lightburn to “Detect My Machine”. It found it perfectly and all I had to do was give it a more specific name (Carverall K15 Pro).

Laser Spot Size Rule

It goes like this: Essentially, the small the wattage of the laser module the smaller the laser spot size. What this means is that you can get a more detailed engraving with a low wattage machine.

Note that I did NOT say you can get a deeper, darker, catch the wood on fire burn.

If you engrave very detailed and very busy widgets then low wattage is the way to go. Don’t let marketing hype fool you. Yep, there is a place and situation for a 60 watt laser but burning the words “Happy Birthday” on a cardboard gift tag at Hobby Lobby isn’t one of those places.

I actually do a lot of tags and place settings when we entertain. It adds a nice touch and the Carverall K15 Pro is the right size for the job.

Quick Trip Around The Carverall K15 Pro And Demonstration

Who Is This Machine For?

Well, certainly anyone, but I’ve always been stunned to find out that someone wakes up one day and decides that they will make a million dollars in a side hustle with a laser engraver. They then proceed to buy the $4000 machine that they have no idea how to operate and have no understanding of how to use the software. Instead of becoming millionaires they become $4000 in debt.

START SMALL. Get an inexpensive machine and learn your craft. The Carverall K15 Pro is PERFECT for this. Then once you have a good idea of what you are doing and LEARN BASIC LASER ENGRAVER MAINTENANCE AND CLEANING, then buy up to a bigger and better, and faster machine.

Do you have any idea how many machines I have seen destroyed over the years due to a lack of preventive maintenance?

Then once you buy up, KEEP YOUR BUDGET MACHINE. No one can run a laser side hustle with one machine unless they hold spare parts sufficient to keep the single machine running.

I challenge you to go to ANY laser engraver forum and just scroll down the list. It won’t be long until you read, “My machine broke and I have orders to fulfill. This is unacceptable.”

Yeah, what is unacceptable is that you never cleaned your lens or let your laser module cooling fan get caked with soot.

Support

I don’t have any experience with Carverall Support other than a discussion I had with them about the magnets on the safety enclosure. That went extremely well.

Here is the deal though. All these laser engravers, with very few exceptions are made in China. It has been my experience that they all work. I’ve been reviewing lasers since 2019 and I’ve only seen one machine that was a dog and I was able to fix that.

When you need support, China is probably around 12 hours in time difference to you. When your machine breaks at noon no one is going to answer the phone.

Also the Chinese have some holiday periods that last a week or so. They shut down, it is cultural and that is simply the way it is. I lived in Asia (Japan) for over 16 years. It is cultural and you aren’t going to change it because your fan crapped out because you never cleaned it. Just as we revere New Years for like 2 days max, they revere it for a week. And here’s the kicker. It isn’t on January first over there. This year it starts on February 6th, 2026. That is right at the height of your Valentine’s Day order fulfillment.

Take a day or so and understand the cultural differences where you laser manufacturers are.

Lastly, like I said earlier all these lasers work. They just do. The thing that makes one company better than the others is After Sales Support.
