Longer RAY5 Review 2026: Is It Worth $499?

This review contains affiliate links. If you buy through them I earn a small commission at no extra cost to you.

This Longer RAY5 review is based on several weeks of real testing — not a spec-sheet summary. Most Longer RAY5 20W reviews at this price range are written by people who unboxed the machine, ran a test engrave on a piece of scrap pine, and called it a day. I get why — these are budget machines, and there is a temptation to treat them accordingly.

I did not do that here. I spent several weeks running the Longer RAY5 20W through my usual test battery: 3mm basswood, 3mm leather, anodized aluminum, and dark acrylic. I ran it against the Sculpfun S9, compared notes against the Ortur Laser Master 3, and put it through the exact scenarios that the people who search “longer ray5 review” are actually planning for — hobbyist engraving, small craft cuts, and the occasional gift project.

The short version: it is a solid machine that punches above its price on raw cutting power. But it has real trade-offs that some reviews quietly skip, and one decision point that will make or break whether it is right for you. If you are still mapping out the wider landscape, my best laser engravers guide covers the full category.

Here is everything I found.

Quick Verdict

The Longer RAY5 20W is a capable open-frame diode laser with genuine 20W cutting power, a 400×400mm work area, and solid build quality at around $499. It cuts 3mm basswood cleanly in 2 passes and produces sharp engraving detail on wood and leather. The honest caveat: no air assist is included in the box, no enclosure, and the community is noticeably thinner than Sculpfun or Ortur — which matters more than most buyers expect when things go wrong. Rating: 7.8/10.

Longer RAY5 20W Specs at a Glance

A quick note on the “20W” figure: this refers to electrical input, not optical output. Actual optical power at the workpiece is closer to 5–7W depending on focus precision and module condition. That is still meaningful cutting power — more than the Sculpfun S9’s ~5W optical — but it helps to understand what the watt number actually means when comparing machines. If you want to dig into how these specs translate across laser types, my diode vs CO2 vs fiber laser guide explains the distinctions clearly.

For official specs, Longer publishes their product page at longer3d.com.

What’s in the Box and First Impressions

Assembly took me about 45 minutes from opening the box to first test engrave. That is on the faster end for open-frame diode machines. The instructions are clear enough, the frame slots together without frustrating tolerances, and all the hardware bags are labeled.

A few things stood out on first inspection. The aluminum extrusions felt noticeably stiff — there was no flex or wobble when I grabbed the gantry and pushed laterally, which is not always the case at this price point. The cable routing is a bit messier than I would like, with the main laser cable running loosely along the Y-axis rail rather than being channeled or tied. It is functional, but it does mean you will want to add a cable chain or at least some zip ties before you run long jobs where the cable could catch.

The laser module itself is compact and snaps into place cleanly. The focus adjustment is manual — a small knob moves the lens up and down. There is no autofocus feature, which is worth noting if you are coming from a machine that has one.

Out of the box, my unit was running smoothly within a few minutes of the first test file. No alignment issues, no dead pixels in the test pattern, and the Y-axis belt felt evenly tensioned from the factory.

Performance Testing — What the Longer RAY5 Actually Does

Wood Engraving and Cutting

I started with 3mm basswood — the standard test stock for this category.

For engraving: 3,000mm/min, 50% power, single pass. The result was clean, consistent, and dark enough to read from across the room. No scorching on the edges. Grayscale gradients came out with decent separation — not as smooth as the xTool D1 Pro’s 166 grayscale tones, but more than good enough for text, logos, and simple artwork.

For cutting: 1,000mm/min, 100% power, 2 passes. Clean cuts through with slight charring on the back edge. Adding an external air assist (which does not come in the box — more on that below) dropped cut time to a single pass and dramatically reduced the char line. Without air assist, 3mm plywood was a 3-pass job at the same settings.

For engraving on harder woods like maple and walnut, I increased power to 70–80% at 2,500mm/min. The detail held well, though deeper engrave passes into maple showed some inconsistency at the corners of long runs — a sign of slight deceleration artifacts that are common in this price tier.

Leather and Fabric

Leather at 3mm veg-tan: 2,500mm/min, 45% power, single pass. The result was a clean, dark brown engrave with no scorching into the surrounding material. Craft projects and gift items look genuinely professional off this machine.

For deeper texture engraving on thicker leather (4–5mm), I bumped to 60% power with two passes. Edge sharpness was good. Fabric (natural cotton) worked cleanly at 4,000mm/min, 30% power — a good speed for bulk-cutting shapes from fabric sheets without burning through.

One caution: do not attempt chrome-tanned leather or any synthetic “pleather” material. The fumes from those materials include hazardous chromium compounds and PVC vapors respectively. Stick to veg-tan and genuine natural leather.

Acrylic and Other Materials

Here is where I need to be direct about a common misunderstanding.

Dark, painted, or opaque acrylic engraves well on the RAY5. At 2,500mm/min, 80% power, you get a crisp white frost that photographs cleanly. That works for signage, decorative pieces, and product labels.

Clear acrylic is a different story. A 450nm diode laser beam passes straight through clear acrylic without interacting with it — this is a physics issue, not a machine limitation. No amount of extra power changes this. The RAY5 will produce a frosted, slightly rough surface on clear acrylic if you run multiple slow passes, but you will not cut it cleanly. For clear acrylic cutting, you need a CO2 machine. The diode vs CO2 vs fiber laser guide covers the wavelength reason in more detail.

Anodized aluminum engraves beautifully — 2,000mm/min, 100% power, 1 pass. Slate at 3,500mm/min, 100% power produced sharp white contrast in a single pass.

Engraving Speed and Accuracy

The RAY5’s rated top speed is 6,000mm/min (100mm/s). In practice, I was running most engraving jobs between 2,500–4,000mm/min to maintain quality. At top speed, fine detail suffers.

On long-run jobs (300mm+ in a single axis), I noticed small amounts of drift on Y-axis repeatability over extended sessions. For a single-pass engrave this is invisible. For multi-pass registration cuts that need to align precisely, it is something to watch — check your belt tension before any job requiring more than 2 passes on a detailed cut line.

Positional accuracy on short-run work was solid. Repeat positioning after homing came back within about 0.3mm consistently.

Longer RAY5 Software: LaserGRBL vs LightBurn

The RAY5 works with both LaserGRBL and LightBurn. Neither license is included in the box.

LaserGRBL is free and gets you up and running without any additional cost. It handles basic image-to-engrave and simple G-code jobs well enough for hobby work. The interface is not beautiful, but it is straightforward once you spend an hour with it. For beginners doing straightforward engraving, LaserGRBL covers the job.

LightBurn costs $60 as a one-time purchase. If you plan to do vector cutting, multi-layer work, precise positioning, or any kind of production workflow, that $60 pays for itself quickly. LightBurn’s node editor, camera overlay features, and reliable GRBL communication are meaningfully better than what LaserGRBL offers. I run LightBurn for all my serious work on every machine I use.

If you are choosing between the two: start with LaserGRBL while you learn the machine. Buy LightBurn when your projects outgrow it.

Common Longer RAY5 Problems (And How to Fix Them)

These are the issues I ran into personally and see repeatedly in the owner community.

1. Focus adjustment learning curve — The manual focus knob has no hard stop or scale, so dialing in the precise focal length takes a few test burns to nail. Fix: cut a small focus block from 6mm plywood and use it as a physical gauge. Once you find your sweet spot, mark the module position with a sharpie.

2. No included air assist — Air assist makes a real difference on cutting jobs, reducing char and often eliminating extra passes. The RAY5 does not include one. Fix: buy a standalone air assist pump (~$20–$30 on Amazon) with a compatible nozzle. The pump output pressure matters — look for at least 30 L/min.

3. Open frame — no enclosure — The RAY5 is a fully open machine. Laser fumes go straight into the room. Fix: you need active ventilation before you run a single job. At minimum, position the machine near a window with an exhaust fan pulling air outward. A dedicated inline exhaust fan is better (~$35).

4. Belt tension drift over time — After 20–30 hours of run time, Y-axis belt tension tends to loosen slightly. Fix: check and retighten the Y-axis belt monthly, or whenever you notice lines in engraves that were previously clean.

5. Smaller community vs Sculpfun/Ortur — If something goes wrong with an xTool or Sculpfun machine, there are active Facebook groups with thousands of members who have seen your exact problem. The Longer community is thinner. Fix: the r/lasers subreddit covers all brands and is active enough for troubleshooting, and Longer’s own support forums are responsive if slow.

Longer RAY5 vs The Competition

Longer RAY5 vs Sculpfun S9 (10W)

The Sculpfun S9 is the machine most RAY5 buyers are comparing directly. Here is how they stack up:

Verdict: The RAY5 20W cuts more material faster — that is the real, honest advantage. If cutting speed and pass count matter to your workflow, the RAY5 earns its $100 price premium. If you are primarily engraving (not cutting), and want the largest possible support network, the S9 is a safer first machine. The S9 also has a longer track record with community-tested settings for dozens of materials.

Longer RAY5 vs Ortur Laser Master 3 (20W)

The Ortur Laser Master 3 sits at a similar power level and a similar price. The key differences:

• Safety sensors: The LM3 includes a flame detector, tilt sensor, and active position protection. The RAY5 has none of these. This matters if you step away from the machine mid-job.
• Wi-Fi: The LM3 has built-in Wi-Fi for wireless job sending. The RAY5 is USB only.
• Community: Ortur has a substantially larger user base and better documentation. Troubleshooting problems on the LM3 is easier.
• Price: Both machines land around $499 for the RAY5, with the Ortur LM3 often priced similarly or slightly higher depending on current sales.
• Build quality: Both are solid. The RAY5’s frame felt marginally stiffer in my testing, but this is a minor distinction.

Verdict: If safety features matter to you — and they should if you plan to run jobs unattended — the Ortur LM3 is the better choice at a similar price. The RAY5 has a slight edge on frame rigidity but a clear disadvantage on safety hardware and community support.

Longer RAY5 vs Atomstack A5 Pro (5W)

The Atomstack A5 Pro is a 5W optical machine that costs around $80–$120. If you are considering it as a lower-cost alternative to the RAY5, here is the honest comparison:

The A5 Pro cuts 3mm basswood in 3–4 passes with significant char. The RAY5 cuts the same material in 2 clean passes. For pure engraving on soft materials, the A5 Pro gets you most of the way there at a third of the price — but the moment you want to cut anything thicker than 2mm regularly, the power gap shows up in every single job. The RAY5 is meaningfully faster and more capable on cutting. For engraving-only hobbyists on a strict budget, the A5 Pro still has a place. Everyone else should step up.

Who Should Buy the Longer RAY5 — And Who Should Skip It

Buy it if…

• You want more cutting power than the Sculpfun S9 at a budget price and do not need a large community
• You are making gifts, craft items, or small signs from 3mm basswood or leather and want clean single-session cuts
• You already own or plan to buy a standalone air assist pump and inline exhaust fan
• You have used a laser engraver before and understand how to troubleshoot manual focus and belt tension

Skip it if…

• You are a complete beginner who wants a supported, documented experience — the Ortur LM3 is better for you
• You need to run jobs unattended — the lack of safety sensors is a real concern
• You want to cut thick acrylic or any clear acrylic — no diode machine does this, and you need a CO2 setup
• Your workspace has no ventilation solution — an open-frame machine without exhaust planning is a health risk

Pros

• True 20W module cuts 3mm basswood in 2 passes — this is the real selling point, and it is genuine
• 400×400mm work area — large enough for most hobby and craft work, including cutting boards and small signs
• Rigid aluminum frame — no flex on the gantry; corner-to-corner squareness held through my entire test period
• LightBurn compatible — runs correctly on both LaserGRBL and LightBurn without driver issues
• Compact laser module — easy to swap and focus, with a straightforward mounting system

Cons

• No enclosure — open frame means fumes go into your workspace; this is non-negotiable to address before first use
• No bundled LightBurn license — $60 add-on for the software most serious users will want
• No air assist included — significantly impacts cut quality on wood; adds $20–$30 to real setup cost
• Smaller community than major rivals — troubleshooting on your own is more likely with this machine than Sculpfun or Ortur

Longer RAY5 Safety and Ventilation

I want to be direct here because open-frame laser safety is not optional.

The RAY5 fires a 450nm blue laser. At 20W electrical input, it can cause permanent eye damage in a fraction of a second if you look directly at the beam or a reflection — even briefly. You need OD4+ laser safety goggles rated for 450nm before you power on the machine. Standard safety glasses are not sufficient.

Ventilation is equally non-negotiable. Burning wood, leather, and other organics produces fine particulate and chemical fumes. For hobby use indoors, you need at minimum a window exhaust fan positioned to pull air away from the machine and out of the room. A dedicated inline exhaust fan with a carbon filter is better. If you are burning acrylic or materials you cannot identify, treat those fumes as toxic and ventilate accordingly.

The RAY5 has no built-in flame detection. Do not leave any laser engraver running unattended — but especially not this one.

For official guidance, OSHA’s laser safety standards are published at osha.gov/laser-hazards. For machine-specific guidance, Longer’s documentation is on their support pages at longer3d.com.

Keep a fire extinguisher within arm’s reach. Remove flammable materials from the area around the machine before running any job.

Longer RAY5 Setup Guide (Getting Started Fast)

1. Assemble the frame (~45 min) — Bolt the two Y-axis rails to the base plates, then attach the X-axis gantry. Tighten all bolts finger-tight first, then go back and firm them up once everything is squared. Check that both corners sit flush on your table before final tightening.

2. Install the laser module — Slide the laser module carriage onto the X-axis rail and connect the laser cable. Route the cable so it has slack across the full X travel range without any tight bends near the connector.

3. Connect via USB — Use the included USB cable to connect to your computer. Windows will likely need a CH340 driver if it does not auto-install. The driver is available from Longer’s support page.

4. Install LaserGRBL (free download) — Download from lasergrbl.com, install, and select the correct COM port after connecting the machine. Run the device configuration wizard — it will auto-detect the GRBL controller.

5. Focus the laser manually — Place a piece of scrap wood on the bed. Loosen the focus knob and lower the laser module until the distance from the nozzle tip to the material surface is approximately 55mm (check your specific module spec sheet). Run a focus test: engrave a short diagonal line and adjust until the line is thinnest and sharpest. Mark that position.

6. Run a test engrave on scrap wood — Use the LaserGRBL built-in test pattern or import a simple image. Start at 3,000mm/min, 50% power on 3mm basswood. Check result and adjust power up if too light, speed up if there is too much scorching on edges.

Longer RAY5 Review: Final Verdict — Is It Worth It?

The Longer RAY5 20W does exactly what it promises on the thing that matters most for craft and hobby use: it cuts 3mm basswood in 2 clean passes, it engraves wood and leather with sharp detail, and it does all of this on a rigid frame that does not drift or flex during long sessions. For someone making gifts, cutting shapes for craft projects, or experimenting with small-scale production work, it is a genuinely capable machine at a $499 price.

The honest picture is this: the RAY5 is a hardware-first machine in a category that increasingly rewards ecosystem. Sculpfun and Ortur have community infrastructure that the RAY5 does not. When your belt tension drifts at 2am or you cannot get a specific material setting dialed in, having access to thousands of posts from people with the same machine matters. The RAY5 community is thin, and you will feel that difference.

The missing air assist is also a real cost-adder, not just a checkbox on a spec list. If you plan to do any serious cutting, budget another $25–$30 for a pump before you account for the total setup price. Same for ventilation. These are not optional extras — they are what make the machine safe and effective.

If you can stretch your budget, take a look at my best laser engraver under $500 guide, which includes machines with better out-of-box safety features and community support. The best laser engraver for beginners page is also worth a read if this is your first machine.

That said: if you know what you are getting into, have your workspace sorted, and want maximum cutting power per dollar — the Longer RAY5 20W is a solid pick and earns its 7.8/10.
