The LaserBeam allows LongMill users to add a laser to their machine quickly and easily. Our LaserBeam uses high-quality components to offer a full 7 watts of power to cut and engrave materials. And of course, the LaserBeam comes with fantastic support from our technical support team.
Each system comes with:
Laser diode assembly
Laser driver
Laser safety glasses
G2 focusing lens
Power supply
Mounting hardware for the LongMill
Additional add-ons, such as laser safety glasses and lenses can be purchased here.
Materials
The LaserBeam can engrave and cut thinner materials with incredible accuracy, such as on wood, paper, leather, and plastics. The LaserBeam has been tested to cut up to 1/4″ on softwoods.
True 7-watt power
The LaserBeam offers full 7 watts of cutting power. Unlike other lasers in the market that list their power rating based on their peak pulse power that claim the same or higher power ratings, the LaserBeam can cut at 7 watts continuously.

Laser Focusing Lenses
Every laser system comes with a G2 lens. Other lenses can add additional focusing options for your laser.
Focal length
When we talk about focal length for focusing the laser, we are talking about the point where the beam of the laser is at its finest. This is the most optimal point for cutting and engraving as it allows the full power of the laser to be concentrated at the finest point. Depending on your lens, your focal point can vary from very close (30mm) to very far (85mm).
A lens with a long focal length works best for high precision engraving and uneven materials, as the beam’s diameter varies less over its distance, whereas a lens with a shorter focal length loses less power over the distance it travels from the diode to the material, making it better for cutting and high power applications.
Efficiency
Some of the power from the laser diode is lost as it reflects off or passes through the lens as well as when it passes through the air. Depending on the lens design, the number of lens elements it has, and the amount of distance the laser beam needs to travel through the air (based on its focal length), the overall efficiency of the lens can vary.
G2 Lens (30mm focal length)
The G2 Lens boasts an efficiency of 95% but reduced precision by increasing the beam profile and divergence. This lens maximizes the power of the diode, ideal for rapid close-range burning and cutting.
G7 Lens (85mm focal length)
The G7 lens has an 88% efficiency and long focal length. This lens strikes a balance between the precision of the 3-element and the power output of the G2, this lens serves as an exceptional all-around option.
G8 Lens (70mm focal length)
The G8 has a 90% efficiency and offers similar advantages to the G7 lens with a slightly shorter focal length.
3 Element Lens (65mm focal length)
The 3 element lens offers a tight beam with a clean profile at the cost of some output power, running at an efficiency of 70%. This lens also has a long focal length, and low divergence; making it a great precision lens.
Safety
Safety
The LaserBeam and any other laser device can cause harm to you or others. Ensure that you follow these safety guidelines
Never let the laser run unattended
Ensure that you have a fire suppression system such as a fire extinguisher nearby in case of a fire. Never leave your laser unattended. Ensure that your laser is turned off when not in use.
Ensure proper ventilation
Use the laser in a well-ventilated environment. Fumes and particulates from cutting or engraving can be harmful. We recommend having a fume extraction system or having an open door or window to provide ventilation.
Wear Eye Protection
Wear compatible laser safety goggles or glasses. Not wearing appropriate eye protection may cause permanent eye damage.
The FDA recommends no more than 5 mw to avoid eye damage. The glasses sold are rated for 0.007 mw or over 700 times better at reducing laser exposure significantly more than the minimum requirement.
Cut only laser safe materials
Never cut materials that can generate toxic fumes or are dangerous to cut, such as
PVC
ABS
Vinyl
Fiberglass
Integrated Driver Safety Features
Key Switch: This key is needed to enable the laser. Once the key switch is turned on, the laser is enabled and the key cannot come out. Only when the driver is off can You can only remove the key.
Remote Interlocks: This allows for additional switches to be added to the laser. An E-stop or other system can be implemented to shut the laser down in the case of an emergency.
Power Fault Protection: If the driver ever loses power the laser will turn off. In case of a power outage, you can have peace of mind knowing that the laser is off whenever power returns.
Emission Indicator: The small LED on the LaserBeam driver will notify you if the laser is on. This becomes useful if operating outside the visible light spectrum

FAQ
Why does the LaserBeam exist?
We created the LaserBeam to tackle several issues our users have had with using other laser systems with their machines:
Inconsistent performance
Many low-cost lasers advertise a high laser power, but these ratings only show the peak power of the laser module, or laser modules are using lower rated diodes that have been overclocked to output higher wattages. This results in a lower lifespan of the lasers, as well as inconsistent cutting and engraving power.
The LaserBeam is designed, tested, and rated for continual use rated at 7 watts, which means you can expect high performance and consistent results every time.
Lack of support
Many users have found that the lack of resources and support from laser suppliers has made it difficult to set up their lasers properly.
The LightBurn is plug-and-play for LongMills, as well as with additional resources and technical support to make adding a laser simple.
Can I use the laser for machines other than the LongMill?
At the time of writing, the LaserBeam system has only been tested on the LongMill. We cannot guarantee that this system will work with other devices. However, we are planning to test compatibility with other CNC machines and systems in the future. Users that are interested in tinkering with the laser should be able to make the LaserBurn compatible with most GRBL based CNC machines and 3D printers using the TTL/PWM input system.
When will the Laser ship?
Batch 1 Pre-orders (ordered between May 14th 2021 – November 5th 2021) have been shipped as of January 12th 2022
Batch 2 Pre-orders (November 6th 2021 – February 28th 2022) will ship before the end of February 2022.

When do you take payment for the laser?
Payment is taken immediately when you place your pre-order.
What does my LaserBeam order come with?
Your order will come with the laser module, electronics, and hardware to attach it to your LongMill. The LaserBeam also comes with resources and guides to help you set and learn to use the laser.
Can I cancel my pre-order?
You can cancel your order with no penalty any time before your order ships. Please contact us with your order number and a request to make a cancellation. A refund will be processed through your original method of payment.
What software do I need?
The laser will be compatible with any GRBL based machine interface software that has a laser/spindle PWM control mode like gSender/UGS/CNCjs
We also recommend checking out these softwares that allow for creating gcode for laser cutting:
We’ve tested the laser to cut up to 6mm or 1/4″ soft woods.
Do the Safety Goggles fit over regular glasses?
Yes they do, we cannot confirm that they will fit every frame type with every face type but it will accommodate most.
How much will the LaserBeam cost after the Pre-order phase?
The price of the laser will remain the same: $400 CAD after the pre-order is over, the only change will be the safety goggles will cost an additional $60 CAD.
