Stock Air Assist Nozzle: Light-weight aluminum air nozzle delivers improved engraving speed and quality, protects your optics from smoke and dust for better performance and laser lifespan.

SainSmart Blue Laser Module perfectly match the SainSmart Genmitsu CNC router kit. With this module, it can absolutely give you different ways to unleash your creativity. It is also an accessory kit for laser engraver or laser cutter.

@beamer3.6 LOL yes, its own in the sense that I get a beam by setting it up incorrectly (as first mentioned), but other than that no real joy at the moment. ref wiring the laser wiring corresponds to the board i.e. PWM to PWM GND to GND 12V to 12V

I was having problems with the laser firing on seting up le5040 engraver from sainSmart

(barely visable at 100% and not burning)

checked $30 there was a mismatch and changed the speed It now works

appears that even though it is a laser engraver machine it shipped with cnc settings

thanks for the insight

Widely compatible design: The SCULPFUN laser module has a clever and widely compatible structural connection device, which can be well adapted to different laser engraving machines, laser cutting machines, 3D printers,...

I currently have what I thought was the most powerful for the price range blue diode laser on my MPCNC and it is maybe 4 watts. I assume this laser is not 10 times as powerful or equivalent to a 40 watt CO2 laser correct?

You really have to watch the china stuff and descriptions. It does not make sense that it is 40 watt laser output. They are claiming 83% efficiency.

The specs say 12V input and 4amp current, this is 48 watt input. They say 40watt output and

25 watt focus. I have no idea what that means. Then a line says 40 watt at 10%.

My guess is you will be able to run only for a very short time, maybe 10% pulse, maybe 10 watts

I figured as much, thanks Robert. I really want something more powerful to strap to my primo because I like dragging the exhaust hose around with the head which lets me have an open machine instead of the standard CO2 enclosure. Waiting for someone to be the first to strap a fiber laser from an engraver machine on one.

This is a 5.5W blue diode laser with a wavelength of 445nm. In order to ensure sufficient cooling, the laser is mounted in a heat sink, which is additionally equipped with a powerful yet quiet cooling fan.

The laser head is connected to the laser control unit by two cables of about 30 cm length each. The yellow/black cable provides the connection to the laser diode. The red/black cable is for connecting the cooling fan.

This component acts as an interface with your CNC, containing all the necessary electronics for processing the PWM signal coming from your CNC, resulting in the laser being supplied with the required voltage at the right time to meet the demands of your projects.

The Laser Control Module is meant to be mounted to the aluminum extrusion profile on the back of your X axis of your CNC by means of the supplied T nuts and M3 screws. A 2.5mm hexagon wrench is required for mounting those screws.

This is connected via the supplied 3-pin connection cable to the corresponding red 3-pin port on your 3018 Pro CNC Controller. Before switching on for the first time, make sure that the signals are connected to the correct pins.

This switch is very important, because many users mistake this as an on/off switch, but in actuality this switch toggles PWM control on and off. PWM control is what your CNC uses to control your laser, so you want this on toggled to On/PWM at all times. If this is toggled off, your laser will fire at full strength at all times, with no way to control it.

The additional 4.0mm/1.7mm DC Power Jack can be used with an external power supply if necessary. However, if the laser module is used with the 3018 Pro or 1018 Pro, you should not have this plugged in, as the laser will draw all the power needed directly from your CNC board.

The first thing you should do is disconnect both sides of the electrical connection to the spindle motor. Then remove the spindle motor from the motor mount. Do not operate the SainSmart 3018-PRO with both the laser and the spindle motor connected!

Slide the laser head into the motor mount so that the corners are in the slots of the motor mount and the cooling fan of the laser head pointing upwards. Position the laser head so that the lower edge of its heat sink is about 60mm above the work piece. At this distance, it is usually very easy to adjust the optimal focal point of the laser at a later time. Tighten the clamping screw on the motor mount, do not over tighten, it just needs to be secure.

The laser head has two 2-pin connection cables, one for the power supply of the cooling fan and one for the laser diode. Make sure that both cables are connected to the yellow and white pin socket of the laser control module as described above.

The laser control unit can be mounted on the rear of the CNC machine on the aluminum profile to the right of the control unit of the CNC machine using the M3 T nuts and screws supplied. Make sure that the cables to the laser head can move freely so that the laser can move in all axes to the limits of its travel.

The above images show the two varieties of 3018 Pro boards currently in circulation. In either case, the red 3-pin port is connected via a wire included with your module which connects on the other end to a red 3-pin port on your Laser Control Module.

Powering on the router and connecting the USB Cable can cause the laser to fire for a short while, so ensure you are wearing the safety goggles. This can also burn the stock depending on what you are using so it makes sense to put something non burnable under the laser beam before turning the router on and connecting to any software.

LaserGRBL is a free program which works with Grbl based routers fitted with a Laser and Laser Engravers. It will be used here to assist with setting the Laser Focus though is capable of both sending GCode and converting images to GCode for Laser Engraving It can be downloaded from

Place something of known thickness above the stock which will not burn and jog the Z axis so the bottom of the Laser Head Heat sink is 60mm from the top. This measurement will make it easier to repeat the focusing on different stock heights or after remounting the Laser of the stock. Or allow the positioning of the laser on the Z axis to avoid having to refocus every time. Focus is adjusted by turning the focusing knob to move the lenses in the shaft in and out of the Laser Head.

The major effect of setting Laser mode on is that the router will turn off the laser when it is making positional moves. If not set this can result in unwanted lines on your engraving as the Laser is positioned to the next cutting point.

Please refer to the manual of your CNC for assembly instructions. Pay attention to the required cable lengths of the supply lines to the laser head and the laser control module. Depending on the machine purchased, you may need to check that individual pins match, or source longer wires.

The laser requires a 12VDC power supply capable of providing at least 3A. If the control module of your CNC cannot provide this, you will need an external power supply. In this case, the +12V lead of the 3-wire cable which is connected to the red pin socket of the laser control module must not be connected to it. The power supply of the laser must then be provided by an external DC power supply unit with 12V and at least 3A. The power supply unit is connected to the laser control unit via the 4,0mm/1,7mm DC jack, located above the ON/OFF switch.

B30635 is a module specially designed for wood grayscale images and micro-engraving.N30820 and N40630 have strong comprehensive capabilities, the optical power is 5.5 - 7.5W output, and the focus is square light spot, good at carving with wood , rubber stamping, glass, transparent acrylic and cutting Plywood, black acrylic, cloth, etc...These two modules are single-beam modules with comprehensive functions and high cost performance. They are the best choice for beginners. The difference between them is that N30820 can be used as air assist through a needle tube, not picky about the air pump. N40630 can install metal The air nozzle but air pump must be oil-free and water-free, so as to ensure that the lens is not damaged.N30610, A40630, A30130 modules have very fine square light spots, and are better at high-resolution engraving and grayscale engraving of hard materials, They are all zoom modules. A40630 and A30130 also have strong cutting ability and are suitable for cutting Plywood, mdf board and black acrylic. N30610 can present 0.02mm detail, A40630 and A30130 are the same optical features, focal point 0.04x0.04mm, the difference in the different air-assisted extension forms and compatible air pumps.A40640 (Artist's Choice) is a classic creative master 2 beam laser module, it is the world's first 2 beam laser diode engraving and cutting module with zoom design, with the best metal engraving ability, fast groove engraving ability, perfect cutting compatibility. Better application on a wider range of materials, The strongest power density (0.04x0.06mm with 12+ optical power)of enables the A40640 to have the top engraving ability, There are very special and top artistic expressions on the carvings of stainless steel grayscale carvings, stone carvings, hardwood reliefs, canvas art, and other materials. The adjustable focal length design enables the A40640 module to have a uniform cutting thickness of 20mm and short-focus fast cutting capabilities. If you only consider 1 module to help you solve all the needs, it is the best choice.F30130, E30130, E40, E80 are the series of modules specially designed by NEJE for long-time cutting. These four modules are fixed focal length modules, which require clean air source support, F30130 is 10mm focal length, good at cutting plywood and metal engraving less than 4mm, E30130 is 20mm focal length, through internal NEJE optical processing, the spot shape is square, suitable for cutting materials with strong symmetry requirements such as model aircraft, E40 is 2 beam module, the spot shape is square, with 12W continuous power output capability, is a cutting module with high cost performance and wide application. E80 is 4 beam module, 20W+ output, it is not recommended for engraving, the focus point is larger, heavy weight and the need to add air assist are the disadvantages of 4xLD. If you have requirements for cutting speed of 3-4mm materials, E80 is the right choice for you, Normally, 500mm/min can cut plywood cleanly, It should be noted that E80 is a 24V input module, which can only support the new NEJE-3-Max machine. The new motherboard of NEJE 3 Max (v1.1.0 and above) supports 24V input. NEJE does not plan to configure a separate machine set for the E80 module. You can Purchase an E80 kit to upgrade your NEJE 3 Max.. In addition to E80 modules, F30130, E30130, E40 can also remove the air nozzle and directly use it for engraving without air assistance.
