Genmitsu is the CNC line from SainSmart, and it has become one of the names people run into first when they search for a desktop CNC router for beginners. A CNC router is a computer-controlled carving machine: you draw a design on your computer, the software turns it into instructions called G-code, and the machine moves a spinning cutting bit along three directions (left-right, front-back and up-down) to carve it into wood, plastic or soft metal. Genmitsu machines run on GRBL, a free, widely supported control system, so there is a big community of tutorials behind every model here.
The six machines below differ mainly in three things: how big a piece they can carve (the work area), how strong the spinning motor is (the spindle or router), and how the axes are driven, ranging from the small 3018-PRO starter kit to the large PROVerXL 6050 Plus and the tall, powerful PROVerXL 4030S.

Genmitsu 4040-PRO CNC Router Machine
Best for: Hobbyists wanting a bigger desktop bed
Pros
- 435 x 400 x 80mm work area
- 32-bit controller, silent drivers
- About 15-minute assembly
- Accepts 65mm or 69mm spindle mounts
Cons
- Spindle not specified in listing
- Lead screws, not linear rails
The Genmitsu 4040-PRO CNC Router Machine is a step up in size from starter kits, with a 435 x 400 x 80mm (17.13 x 15.75 x 3.15 in) working area. That is roomy enough for house signs, carved reliefs, prototypes and general woodworking. The listing names wood, acrylic, MDF, nylon and carbon fiber composites as workable materials with the right bits and settings.
Its motion system uses dual 16mm steel tubes on each axis with lead-screw drives, and a 32-bit controller with silent Toshiba drivers keeps things quieter. A reinforced hybrid spoilboard (the sacrificial board you cut on top of) has a center aluminum support bar to reduce sagging. Pre-assembled modules let you build it in about 15 minutes, according to the listing, and the Z-axis carriage accepts 65mm or 69mm spindle mounts, with 3-pin ports for accessories like air assist and handheld MPG controllers. The listing does not specify which spindle is included or its power, so check the product page before buying.
This suits someone who has outgrown a tiny machine, or a gift for a woodworker ready for bigger pieces. Buyers who want linear rails and a stronger router should look at the 4040-PRO MAX next.

Sain Smart
SainSmart Genmitsu 4040-PRO MAX CNC Router with 710W Trimmer
Price and specifications are read from the Amazon product page and can change.
SainSmart Genmitsu 4040-PRO MAX CNC Router
Best for: Makers wanting 4040 size with more power
Pros
- 710W trimmer included
- Linear guideways on X and Z
- 100mm pass height
- T-track in spoilboard
Cons
- Heavy at 24 kg
- Listing voltage details unclear
The SainSmart Genmitsu 4040-PRO MAX CNC Router keeps a similar footprint, with a 410 x 405 x 77mm work area, but upgrades the hardware. It ships with a 710W trimmer with a digital display, a compact router much stronger than a small hobby spindle. The X and Z axes use linear guideways, rail systems that resist wobble better than round tubes, which the listing says improves stability and precision.
The spoilboard gets a central aluminum bar that doubles as a T-slot, so you can clamp pieces in more ways. The pass height, meaning how tall a piece can fit under the gantry, is 100mm, which SainSmart says is over 40% higher than the PRO version. The machine weighs 24 kg. The listing shows 24 volts in its specs, which likely refers to the control electronics rather than the trimmer, so the exact power setup is not clearly specified.
Pick this if you like the 4040 size but want to cut harder materials and work faster. If you want an even taller clearance and a 32-bit brain, the PROVerXL 4030S is the alternative.
Genmitsu PROVerXL 4030 V2 CNC Router for Accurate Small-Shop Work
Genmitsu
Genmitsu PROVerXL 4030 V2 CNC Router Machine with Closed-Loop Stepper Motor
Price and specifications are read from the Amazon product page and can change.
Genmitsu PROVerXL 4030 V2 CNC Router
Best for: Small shops wanting closed-loop motors
Pros
- Closed-loop NEMA 23 steppers
- 1204 ball screws
- Up to 5000 mm/min travel
- 110mm Z height
Cons
- 400 x 300mm bed is mid-size
- 8-bit controller per 4030S listing
The Genmitsu PROVerXL 4030 V2 CNC Router is the model built around closed-loop stepper motors. A normal stepper motor moves in tiny steps but cannot tell if it missed one, which can shift your cut. A closed-loop motor checks its own position and corrects, so the listing promises no step loss and lower noise. It uses NEMA 23 motors, 1204 ball screws for precise movement, and reaches travel speeds up to 5000 mm/min.
The work area is 400 x 300 x 110mm, and the item highlight lists a 400W spindle. A T-slot hybrid table helps hold odd-shaped pieces, and the GRBL-based board connects over USB to software such as Candle or Universal Gcode Sender. Materials named include wood, plastics, soft metals, PCB and MDF.
It suits hobbyists and small business owners making repeat products such as coasters, name plates or small parts, where accuracy over many runs matters. The newer 4030S listing notes that the V1 and V2 use 8-bit controllers, so those wanting the faster 32-bit board should consider the 4030S.
Genmitsu PROVerXL 6050 Plus CNC Router for Big Projects
Genmitsu
Genmitsu PROVerXL 6050 Plus CNC Router Machine for Big Projects
Price and specifications are read from the Amazon product page and can change.
Genmitsu PROVerXL 6050 Plus CNC Router
Best for: Large signs and furniture parts
Pros
- 600 x 500 x 115mm work area
- Dual HG-15 linear rails
- Aluminum T-track grid
- Extra 65mm spindle holder
Cons
- 300W spindle is modest
- Needs a large bench
The Genmitsu PROVerXL 6050 Plus CNC Router has the largest bed here at 600 x 500 x 115mm (23.62 x 19.69 x 4.53 in). It uses dual HG-15 linear rails with a single Y-axis T10 lead screw, an all-metal frame and a 300W spindle motor. The spoilboards sit on aluminum T-track extrusions, so individual MDF boards can be replaced when worn.
The core system arrives pre-assembled, and all NEMA 23 stepper motors have manual jog wheels, letting you nudge the spindle into position by hand. An extra 65mm spindle holder is included for a future upgrade, and SainSmart offers add-ons like an offline controller and dust shoe, sold separately. If you enjoy browsing shop gear, our look at a metal fabrication laser welder covers another big-project tool.
This is for makers who want large signs, cabinet doors or tabletop inlays. The 300W spindle is the modest part, so buyers who mostly cut small but hard parts may prefer the 710W models.
Genmitsu PROVerXL 4030S CNC Router Machine for Tall and Tough Jobs
Best for: Tall workpieces and harder materials
Pros
- 710W router, up to 30000 rpm
- 130mm pass height
- 32-bit MCU
- Genmitsu App wireless control
Cons
- Heaviest here at 33 kg
- Work area not stated in listing
The Genmitsu PROVerXL 4030S CNC Router Machine is the newest-looking PROVerXL here. It pairs a 710W compact router (up to 30000 rpm) with a 130mm pass height, the tallest clearance in this lineup, which helps with thick stock and rotary projects. The listing claims repeatable positioning accuracy of plus or minus 0.05 mm, thanks to an upgraded Z-axis linear guideway.
A 32-bit MCU replaces the 8-bit controllers of the 4030 V1 and V2, and operating speed rises from 2000 to 5000 mm/min with noise kept under 65 dB. The modular design assembles in about 20 minutes, and the Genmitsu App offers wireless control and monitoring from your phone. It weighs 33 kg. The listing does not specify the X and Y work area, though the name suggests the 4030 family size.
Choose it if you want power, height and phone control in one machine. Beginners on a small bench may find it more than they need.
Genmitsu CNC 3018-PRO Router Kit for First-Time Makers
Best for: Absolute beginners and classrooms
Pros
- Compact 300 x 180 x 45mm area
- Offline controller included
- GRBL with Candle support
Cons
- Low-power spindle for hard materials
- Small, shallow work area
The Genmitsu CNC 3018-PRO Router Kit is the classic starter. It is a compact 3-axis machine with a 300 x 180 x 45 mm working area, 15.3 pounds in weight, and a spindle listed at 120 watts and up to 20000 rpm. Materials named include wood, acrylic, PVC, plastic, PCB and soft aluminum.
The big beginner-friendly touch is the included offline controller, which runs basic functions and compatible G-code without a computer attached. When you want more control, GRBL and Candle software take over. The upgraded assembly and raised base make it an approachable first build for home workshops, classrooms and maker spaces.
It is the easiest gift for a curious teen or a first-time hobbyist. Once projects outgrow the small bed or light spindle, the 4040-PRO or PROVerXL models are the natural next steps.
How to Choose the Right Genmitsu CNC Router
Work area. Measure the biggest thing you want to carve. Coasters and PCBs fit the 3018-PRO; signs and trays suit the 4040 or 4030 machines; big panels need the 6050 Plus.
Spindle power. More watts means cutting harder materials and deeper passes more easily. The 710W routers on the 4040-PRO MAX and 4030S sit at the top, the 400W and 300W spindles are mid-range, and the 3018-PRO is for light work.
Motion system. Linear rails and ball screws resist flex; closed-loop motors avoid lost steps. If accuracy on repeat jobs matters, the 4030 V2 and 4030S are strong picks.
Height and space. Z height decides how thick a block can go under the bit. Also check your bench, electrical setup and whether you need wireless control; if you plan to run the Genmitsu App, a strong home network such as a WiFi 7 router helps in a garage workshop.
