Powerful but pricey CNC upgrade with strong value only at the low end

Is the Lunyee 3018 Pro Ultra worth buying? Yes, if you want a more capable 3018-class CNC with upgraded hardware and can justify the £645.36 price; no, if you are expecting entry-level pricing or a plug-and-play machine.

First impressions

At £645.36, the Lunyee 3018 Pro Ultra sits in a serious hobbyist-to-prosumer price bracket, especially for a 3018-format machine. Its 4.2/5 rating from 325 reviews suggests buyers generally like what it does, but the score also leaves room for real concerns. The listing positions it as an upgraded metal-capable engraving machine, and the feature set backs that up: a 500W spindle, 80mm Z-axis height, HGH15 linear guide on the X-axis, and 2040 X-axis / 4040 Y-axis profiles.

What the upgrades actually mean

The biggest selling point is the move beyond a basic desktop engraver. The 500W spindle should give it more headroom than lower-power hobby machines, while the HGH15 linear guide and heavier-axis profiles are aimed at improving rigidity and precision. That matters most when cutting or engraving harder materials such as metal, wood, acrylic, PCB, and MDF, which are all explicitly listed as supported materials.

The scale grid aluminum plate platform is another practical upgrade. A one-piece machined and molded aluminum work surface is a better sign than a flimsy table because flatness and strength affect both accuracy and repeatability. If you plan to do repeat jobs, jigs, or small production runs, that kind of platform is more useful than flashy marketing language.

How does it perform in real use?

On paper, this is a more capable machine than a basic 3018 Pro model because the improvements focus on the parts that affect rigidity and consistency. The higher 80mm Z-axis should help with clearance, and the upgraded guide system should reduce flex compared with simpler rail setups. Those are the right places to spend money if your goal is cleaner engraving and less chatter.

That said, the product is still a compact CNC, not an industrial mill. The listing’s own wording points to “engraving” and “milling” in a small-format context, so expectations matter. If you want to work across metal, wood, acrylic, PCB, and MDF, this machine is designed to broaden material compatibility, but the buyer should still treat it as a desktop tool with limits rather than a heavy-duty fabrication machine.

Build quality and setup

Build quality looks like a strong point. The integrated switching power supply is meant to improve installation efficiency, and the machine includes pre-assembled main parts plus clear cable management. Lunyee also provides installation and wiring videos, along with a paper user manual, which is helpful for a machine class that can otherwise be frustrating to assemble.

The inclusion of limit switches and an emergency stop is also important. Those are not glamorous features, but they matter for safety and repeatability. The machine also uses GRBL offline control, which is useful if you want to run jobs without keeping a computer tethered to the machine.

Is it good value for money?

This is where the review gets mixed. The current price of £645.36 is close to the average price of £641.37, so the machine is not overpriced relative to its own recent history. However, the all-time lowest recorded price was £404.00, which is dramatically lower than today’s figure. Since the price data shows 40 points over about 40 weeks, the current price looks normal, but not cheap.

Compared with the listed alternatives, the value picture is very different. The competitor products shown are inexpensive accessories and consumables: a 3D printer enclosure at £39.99 with a 4.6★ rating, and Creality PLA filament at £22.09 and £17.99, both also rated 4.6★. Those items are not direct CNC competitors, but they highlight how expensive this machine is relative to common maker purchases. In other words, this is a major tool investment, not an impulse buy.

How does it compare to alternatives?

There are no direct CNC competitors in the supplied data, so the fairest comparison is against the broader maker-tech spend. At £645.36, the Lunyee costs many times more than a printer enclosure or filament, yet it targets a much more advanced job: precision cutting and engraving. If your workshop needs CNC capability, those cheaper items are irrelevant; if you only dabble in maker projects, this price is hard to justify.

Final take

The Lunyee 3018 Pro Ultra looks like a thoughtfully upgraded desktop CNC with real hardware improvements, not just cosmetic changes. Its strongest points are the 500W spindle, linear guide upgrade, solid aluminum platform, and safety/control features. The main drawback is simple: £645.36 is a lot to pay for a 3018-class machine, especially when the all-time low was £404.00.

Bottom line

Buy it if you specifically want a compact CNC with better rigidity and are comfortable paying for the upgrade path. Skip it if you want the lowest cost entry into CNC or if you need a machine that clearly outclasses the limitations implied by a desktop 3018 format.
