Runs whole jobs from its own screen, no laptop tied to the bench.

The reason to shortlist this one is the 3.5-inch touchscreen running AlgoOS (the machine’s own onboard operating system). You get hundreds of preset designs, saved custom projects and over-the-air updates right on the unit, so the computer can stay in the house. Money-wise it lands in the budget-friendly tier, which is unusual for a machine with onboard control.

What it does well is the basics. The 10W laser is fine for wood, acrylic, leather, glass and coated metal, and the 0.05mm spot keeps fine detail readable. The 15.7″ x 17.1″ work surface is the surprising part — it is a genuinely large bed for the money. Two connections stand out too: 2.4G Wi-Fi for hooking it to your network, and full compatibility with LightBurn and LaserGRBL if you outgrow the built-in software.

The honest catch is that 10W takes patience on thicker cuts, and a small number of owners hit a mid-job stall with a “lost communication with driver board” error. That is not every machine — most user feedback clusters around how easy it is to run once you learn to set the laser height for each material. Wood engraving leaves a real burning smell, so plan on ventilation or run it outdoors.

A square 400mm bed and a 0.06mm spot for detail work without a laptop.

Square work areas are underrated, and that is exactly what this Longer gives you — 400 x 400mm, equal on both sides. The engraving spot is 0.06mm x 0.06mm, which is what makes fine lettering and detailed line art come out crisp rather than mushy.

Cutting numbers back up the claim. It cuts 0.8 inches (20mm) of wood board and 1.2 inches (30mm) of acrylic, and the dual-beam design reaches 10,000mm per minute engraving speed. A 32-bit core motherboard (the control board that runs the motion) keeps the head moving steadily through long jobs. Connectivity covers Wi-Fi, USB cable, app and TF card, and the 3.5-inch touchscreen means you can run offline.

What makes it easy to live with is the support side. Longer bundles the tools and accessories in the box with installation guides, offers lifetime technical assistance and 24-hour customer service — and the service reputation holds up in the owner feedback. It is not the fastest machine here, and the price sits in the mid-range tier rather than the bargain bin, so it earns its spot on comfort rather than raw speed.

Double the diode power with a color palette the 10W machines cannot match.

Power is the whole story here. The 20W module cuts 15mm (0.59″) pine, 0.05mm (0.002″) stainless steel and 8mm (0.31″) acrylic in one pass, and up to 25mm wood and 35mm acrylic with multiple passes. The maximum engraving speed reaches 24,000mm per minute, twice the pace of the 12,000mm/min class of machines. Under the hood a 240MHz ESP32 chipset (the processor that drives the motion and the jobs) keeps the carriage stable at speed.

Color engraving is where this machine earns its keep. A 256-color palette (the color tones the laser produces on metal) pairs with a 0.08 × 0.1mm spot and 0.01mm precision, giving softer transitions and stronger contrast on stainless steel, metal, leather and glass. A single unit can also drive multiple machines at once, which suits studios running several units in parallel.

Control is straightforward: a 3.5-inch touchscreen shows progress live and lets you adjust parameters mid-job, and it works with LaserGRBL, LightBurn and LONGER’s own LaserBurn software. The dip in the crowd reaction is software cost — one owner’s read is that you will want paid software rather than the free option — so budget for that in your head. There is also a genuine speed-to-noise trade: this is a louder machine than the 10W units because the laser head carries a powerful cooling fan.

A modular frame you can build in about twenty minutes and run from your phone.

Assembly is this machine’s headline, and that matters — the integrated linear guide structure (a rail system that keeps the head tracking straight) means fewer parts to align and better precision once it is built. The aluminum alloy frame and modular design are there for durability as much as looks. Buyers report getting it running in roughly 20 minutes out of numbered part bags.

On performance, the output is 20000mW, the laser class is 4, and the dot compression technology produces 0.08 x 0.1mm dots. Engraving speeds reach 400mm/s, which cuts processing time across wood, acrylic and metal. A cross-line light plus built-in limit switches hold engraving accuracy at 0.01mm, and the modular design supports a removable magnetic protective cover, safety glasses and a tilt-angle safety beep that sounds past 15 degrees.

Control options are the flexible part — Type-C or USB stick for job files, plus the ATOMSTACK app, PC software, LightBurn and LaserGRBL. The honest limitation is documentation. The free app cannot set travel speed and engraving speed separately, so the head moves at engraving feed when you would rather it hustle, and the paper instructions are thin enough that most owners end up in LightBurn. A few note the gantry cables can snag without added drag chains.

Arrives pre-assembled with a camera that picks settings for you.

For a first laser, the Falcon A1 strips out almost every setup headache. It comes fully pre-assembled — zero build required — and the built-in camera recognises the material in front of it and applies the recommended engraving or cutting settings, so you are not guessing at power and speed. Precision holds at 0.05mm with an advanced CoreXY system (a belt layout that moves all four corners together for faster travel), and speed reaches 600mm/s.

The enclosure is the part that matters most in a home. It is a Class 1 machine, blocks 99% of laser light, and reduces smoke and noise, so you can run it without goggles. The double-door layout with transparent panels lets you watch the job and load material from the side, and a Falcon roller kit lets you engrave curved and round objects like tumblers and bottles. It cuts 6mm wood in a single pass.

Software is where the split in feedback shows. Setup and beginner-friendliness draw the strongest praise, and the enclosed design is repeatedly called out as the reason people chose it over open-frame options. The friction points are real and worth naming: several owners hit connection issues, initially over USB-C and, on some units, over Wi-Fi, and the included cables run short enough that the machine wants to sit near your computer. The camera also needs calibrating before the full-area view lines up accurately.

The CO2 route: a sealed tube cutter built for acrylic and leather.

This is a different animal from the diode machines above. A CO2 tube laser (a sealed glass tube filled with gas that produces the beam) cuts acrylic and leather cleanly in a way diodes struggle to match. The 45W tube slices 0.4″ (10mm) acrylic and 0.31″ (8mm) wood, and the maker claims 1.5–2× faster cutting and 15–20% more depth than the lower-power version. Engraving tops out at 300 mm/s, which is the slowest speed in this roundup and honest for a CO2 design.

The setup details are suited to a real workshop. A compact 12″ x 8″ workspace takes both flat and irregular materials, with a honeycomb bed for flat items and a detachable base plus optional rotary axis for cylinders and taller pieces. A built-in 45° air assist adjusts airflow based on laser power to clear smoke, protect the lens, reduce wood carbonization and lower fire risk. It runs LightBurn and LaserGRBL, and safety covers door protection, water protection, an emergency stop and a flame-retardant acrylic panel.

Two things a buyer should weigh honestly. First, a CO2 laser needs the tube and water cooling maintained, and setup is not a beginner task — the machine carries a Class 2 rating and the manufacturer cites a 0.827 mW output power figure. Second, this one shows up occasionally with shipping damage and alignment issues. Support earns its reputation, though: an owner who was new to CO2 work got a video consult that walked them through alignment.

A 3.39kg laser you can carry to the job and align in seconds.

Portability is the entire pitch, and the numbers back it. The LP2 Plus weighs 3.39kg — 24% lighter than the maker says comparable machines run — so it can travel in a bag rather than being bolted to a bench. A multi-angle laser head open up engraving on angled or hard-to-reach surfaces, from car interiors and walls to furniture that never leaves the room.

Speed is the other headline. It engraves at 4000mm/s, which the maker claims is 6x faster than the older LP2. A 10W 450nm laser paired with an upgraded F-theta lens (a flat-field lens that keeps the beam sharp across the whole work area) delivers 4K-detailed engraving, 1.5× stronger cutting power and cuts up to 6mm basswood in a single pass. Dual red-dot focus lets you line up the material in seconds without a ruler.

Where it earns its keep over a fixed machine is material range — wood, leather, acrylic, coated metal, glass, stone, cork, rubber, paper, and even food. The app draws strong comments for simplicity, and setup is quick enough that a beginner can run it the same day. Its small size is also its limit: this is not the machine for large signage, and a few owners mention units arriving that needed a return. At 11.22 x 7.01 x 11.42 inches, storage is not a problem — the bench footprint just has to be planned around.

The fiber laser that marks 30+ colors directly into stainless steel.

Fiber lasers do the one thing diodes cannot: mark bare metal, permanently, in color. This G2 Plus uses a 1064nm fiber laser (a wavelength absorbed by metal, unlike the diode machines above) at 20W, and it produces over 30 different colors on stainless steel and titanium. A high-speed precision galvanometer (a mirror system that steers the beam instead of moving a head) pushes engraving speeds to 15000 mm/second, which is a different order of speed from the gantry machines.

Resolution options are 2k, 4k or 8k, with engraving accuracy of 0.001mm — fine enough for detailed work that would blur on a diode spot. The engraving area is 150 x 150mm, and an electric lifting column means you press a button to focus instead of turning a dial. Dual red light positioning and a fully digital Galvano scanning system support square and graphic previews for quicker setup. It connects over Wi-Fi and USB, is compatible with LightBurn, and the detachable structure lets you take the head off the bench for awkward jobs.

The trade-offs are honest ones. It is a Class 4 laser, so eye protection, the included protective cover and a proper exhaust setup are not optional. The 150 x 150mm area is small, which is standard for fiber galvo machines but still worth knowing before you buy. There was one report of a unit that burned out after 20 minutes, though GWEIKE replaced a machine with a power supply issue within days in another owner’s case.

Twice the fiber power of the G2 Plus for deeper marks and faster batches.

If you already know you want fiber, this is the step-up. The 50W 1064nm fiber laser (50,000mW) doubles the output of the G2 Plus above, and the difference shows in the depth — it deep-engraves into metal, cuts metal, and does 3D carving that shallower modules cannot. That power increase matters most on challenge coins and dense metal parts, where the extra watts translate directly into penetration rather than a slower multi-pass run.

The speed and accuracy numbers mirror the G2 Plus at 15000 mm/s and 0.001mm accuracy, with HD 8K engraving resolution for fine detail. Color capacity is higher too: over 90 vibrant colors on stainless steel and titanium, versus the 30+ on the smaller unit. The engraving area is 150 x 150mm with an electric lift column for one-button focusing, and dual red light positioning speeds up material preview. It supports GLaser and LightBurn and covers Wi-Fi and USB file transfer.

Where a buyer should be careful is reliability at this power level. The setup draws the strongest positive feedback, and support is responsive — in at least two cases where a unit failed, the company sent a replacement quickly. But a mixed pattern shows up in the reliability feedback, with some owners reporting a failure within a few weeks of use. That is worth knowing if the machine is going straight into a paying job. One buyer also noted it works well on stainless and plastic but struggles on bare aluminum, which only carries anodizing or coating marks.

Metal and wood from one machine, without switching hardware mid-job.

This is the only machine here that runs two lasers in one housing. A 60W MOPA fiber laser (a fiber laser whose pulse timing can be tuned, which is how it produces consistent colors) and a 40W diode handle metal, wood, acrylic, leather, glass, rubber and fabric from the same setup, so you are not swapping units between a metal job and a wood job. The fiber cuts 2mm metal; the diode cuts 20mm acrylic and 23mm wood.

Color engraving reaches over 100 consistent colors on metal, and the preset color files let you engrave a color matrix in one click instead of testing one tone at a time. The fiber side also supports black marking on aluminum, laser cleaning and thin metal welding. Industrial speed sits at 15,000mm/s, and the maker says the 60W MOPA cuts 3D embossing time by up to 80% compared to 20W fiber lasers. Two 48MP AI cameras (48MP describes the camera resolution) lift positioning accuracy to 0.2mm.

The catch is the learning curve and the work area. The 8.7″ x 8.7″ space expands to 8.7″ x 19.7″ if you add the auto conveyor for batch work, but the base bed is the smallest in this roundup alongside the fiber galvos. And it is a Class 4 laser at 60,000mW fiber and 40,000mW diode output, so ventilation and eye protection are mandatory. Beyond that, tuned-up performance is genuinely industrial: production users describe clean, permanent multi-color results on metal coins with consistent batches once settings are dialled in.
