Learn all about the Acmer Ascarva 4S CNC Routing Machine from unboxing, setup and getting started!

Acmer Ascarva CNC Router Machine

I was asked by Acmer to review one of their new tools, I asked for the Laser Cutter...what arrived was the Acmer Ascarva 4S CNC Routing Machine.

Getting the wrong tool in the mail is… not exactly the dream start to a review. 

But sometimes those curveballs end up being surprisingly useful—and that’s honestly where I landed with the Acmer Ascarva CNC router.

I originally expected a laser machine, something right in my crafting comfort zone. 

Instead, I opened a surprisingly big box and found myself staring at a full CNC machine. 

Not exactly what I had planned to add to my workspace—but as a reviewer (and curious maker), I decided to lean in and give it a fair shot.

First Impressions & Unboxing

Right out of the gate, the packaging was solid. 

The Acmer Ascarva 4S CNC Routing Machine arrived in good condition, neatly organized, and well-protected. 

The components felt thoughtfully packed, and nothing appeared damaged or loose during shipping—which is always a good sign when dealing with precision tools.

The Acmer Ascarva has a modular design, which is great in theory and in practice—but it does mean assembly is required. 

And by “assembly,” I mean quite a bit of it.

Acmer CNC Assembly Experience

It took my husband and me about an hour to fully assemble the machine. There are a lot of screws. Like… a lot. It’s not overly complicated, but it is time-consuming, especially if you’re new to building machines like this.

The included tools technically get the job done, but they’re not the highest quality. We quickly switched to our own tools, which made the process smoother and faster.

That said, the instructions were clear enough, and we didn’t run into any major roadblocks—just the occasional minor issue like aligning parts or tightening everything evenly.

➡️​Once assembled, the build quality really stood out. The frame feels sturdy, and the overall construction gives you confidence that it can handle consistent use. It’s not flimsy or toy-like—it feels like a great machine meant for real projects.

The “Now What?” Moment

Here’s where things got a little… interesting.

After assembly, the CNC machine sat on our table for about a month. Why? Because it doesn’t come with its own dedicated software. That was honestly one of the biggest hurdles in the overall user experience.

If you’re brand new to CNC routing, this could feel overwhelming. There’s a bit of a learning curve just figuring out what software to use and how to get started.

I ended up watching a tutorial from The Laser Channel, which helped point me in the right direction.

Walking viewers through the software, Easel and configuring it with the Acmer machine.

From there, I started up Easel, which offers a 14 day free trial without requiring a credit card—super helpful when you’re just testing the waters.

Getting It Up and Running

Once I finally dove in, things started to click.

Connecting the machine and getting the spindle going wasn’t too difficult once I had the right setup, and after a bit of trial and error, I was able to run my first test.

That moment—when the bit starts spinning and the machine actually begins carving—is incredibly satisfying.

Working Area & Capabilities

The AAcmer Ascarva 4S CNC Routing Machine offers a decent working area for hobbyists and beginners. 

It’s not massive, but it’s large enough for small to medium projects like signs, decorative panels, and craft pieces.

For someone just getting into CNC routing, the work area feels like a sweet spot—not too overwhelming, but still capable of handling larger projects when needed.

Materials & Testing

I tested a few different materials to see how the machine handled them.

First up were the sample materials included with the CNC machine. These appeared to be some sort of resin composite. While they cut fine, the dust had a strong smell—which immediately made me think, “Yeah… I probably shouldn’t be breathing this.”

That’s not necessarily a fault of the machine, but it does highlight the importance of proper ventilation and safety precautions when working with various materials.

Next, I moved on to birch plywood. This gave me much better results. The cuts were cleaner, and the overall finish looked more polished.

If I were to continue using this CNC machine regularly, I’d likely stick with MDF or mm base wood for consistency. MDF, in particular, seems like it would be ideal for achieving smoother results and better fine details.

Project Results

I completed three routed projects during my testing phase. None of them turned out absolutely perfect—but they were good enough to show the machine’s potential.

With more time to get everything dialed in—like feed rates, depth settings, and material selection—I’m confident the results would improve significantly.

That’s an important thing to understand about CNC machines: there’s a learning curve. You don’t just hit “go” and get flawless results immediately. It takes a bit of practice and experimentation.

Software Experience (Easel)

Easel ended up being a great starting point.

One of my favorite features is that it estimates how long a project will take before you begin. 

That’s such a nice feature, especially when you’re planning your time or deciding whether to start a project late in the day.

The interface is beginner-friendly, and it made the transition into CNC routing much less intimidating.

Safety & Practical Considerations

CNC machines create dust—sometimes a lot of it. And depending on the material, that dust can be unpleasant or even unsafe to inhale.

The dust was super well managed. The spindle bit is really fine and it only routes a small amount at a time, so the dust does not kick up or even leave the platform, so it's easy to clean up.

I definitely recommend using a dust collection system or at least working in a well-ventilated area. A smoke air purifier or shop vacuum setup would go a long way here.

The machine itself includes basic safety features, and while it doesn’t have a full enclosure, you can absolutely build or buy one if needed.

Who This Machine Is For

This is where my perspective really shifted.

At first, I wasn’t excited about receiving a CNC machine. It wasn’t what I wanted, and it pushed me out of my comfort zone.

But after spending time with the Acmer Ascarva 4S CNC Routing Machine, I can honestly say it’s a great product for the right person.

If you’re a beginner looking to get into CNC routing, this is a solid entry point. It’s approachable, reasonably easy to assemble, and capable of producing quality results with a bit of practice.

It’s especially well-suited for:

• Hobbyists
• DIY enthusiasts
• Small business owners making custom signs or decor
• Anyone curious about CNC without wanting to invest in a high-end machine right away

Customer Support & Brand Impression

While I didn’t have to rely heavily on support, it’s worth mentioning that Acmer’s team has a presence online and appears to be actively engaged with their community.

Having access to a support team and resources—like tutorials and forums—makes a big difference when you’re learning a new tool.

A Quick Note on Acmer Laser Machines

Even though I ended up with the CNC machine instead of a laser machine, I was originally excited to explore Acmer’s laser lineup—and honestly, it’s easy to see why they’ve become so popular with makers. 

Acmer offers a wide range of options, from the acmer p series like the Acmer P 3 48W to the acmer s models and the s pro line, all designed to give users flexibility depending on their needs and budget.

Many of these machines feature a powerful laser module with different watt laser configurations, including a 48 w laser and other w module options, making them capable of both laser cutting and detailed engraving. What really stands out are the thoughtful key features, like a built-in camera for precision placement, air assist for cleaner cuts, and compatibility with LightBurn software—something every laser enthusiast appreciates. 

Their systems are designed to handle various materials, from mm pine and mm base wood to cast 3 mm acrylic and even stainless steel with the right setup. The corexy structure helps improve speed and accuracy, putting them in the running for the best budget laser engraver category.

Acmer also leans into a modular design, offering upgrades like a 2-in-1 laser head, blue diode laser, laser lens enhancements, and accessories like an air pipe or smoke air purifier for a better workspace.

Newer models like the acmer ap expand the work area and offer options like a full enclosure, making them great for batch work, intricate designs, and even large wooden signs. Backed by acmer’s customer service team, a month exchange warranty, and ongoing updates through social media, exclusive content, early sale access, and new arrivals, Acmer is clearly focused on building a connected ecosystem. 

From a new startup to experienced creators, their lineup delivers a good experience with clever design, reliable components like the main board, power supply, and power cable, and the flexibility to grow—whether you're using a 10 w diode head, experimenting with an IR laser, or exploring hybrid setups alongside something like the Ascarva S CNC router machine.

That's it--let's sum up!

So… did I end up loving the fact that I received a CNC machine instead of a laser? Not exactly.

But did I gain a new appreciation for what CNC routing can do? Absolutely.

The Acmer Ascarva 4S CNC Routing Machine is a great machine for beginners and anyone curious about expanding their creative toolkit. It’s not perfect—there’s a learning curve, and the lack of included software can slow you down at first—but once you get past those hurdles, it opens up a whole new world of possibilities.
