SCM4.2W Laser Kit for Pro and Elite CNCs by JTech - AX9-ALK42
Engrave on wood, leather, acrylics, and many other materials. Cut thin and soft woods like Balsa, Basswood, and many other types of materials like foam, paper, cloth and acrylics.
The Axiom CNC laser by J Tech Photonics raises the bar in CNC accessory lasers. Precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, ESD protection, current limiting, and the list goes on. The US Federal Government has a list of things that are required for operating these high power class 4 lasers. They might seem trivial, but they could save your eyesight!
Features
-
Key Switch: A key is needed to enable the laser. When the key switch is turned on, the laser is enabled and the key CANNOT come out. You can only remove the key when it is disabled. This feature is good if you have curious children or have your laser in a shared area and want to limit use. Just take the key out and hide it!
-
Remote Interlocks: This feature allows for addition of a switch on your enclosure so when it is open, the laser will automatically turn off. An interlock switch is also installed on the rear surface of the laser which insures that if the laser is removed from your Axiom CNC router, the beam is interrupted. They’ve also added an E Stop button for the laser, which is always good for if you need to stop the laser quickly!
-
Power Fault Protection: In the event of a power failure, your laser will be disabled, preventing the beam to illuminate as the power is restored. Simply press the reset button and you are back in action!
-
Emission Indicator: The small little LED on the front to let you know when your laser is on.

Maintenance Tips
-
Keep optics clean: Regularly clean laser lens and mirrors with approved optical wipes to maintain consistent beam power and engraving precision.
-
Maintain proper alignment: Check and recalibrate laser alignment frequently to ensure accurate cutting paths on CNC systems.
-
Prevent overheating: Avoid long continuous runs at full power; allow cooling intervals to extend diode life.
-
Dust control: Operate in a clean CNC environment; dust and debris can reduce performance and damage optics.
-
Secure mounting: Ensure the laser module is tightly fixed to prevent vibration during high-speed CNC motion.
-
Cable management: Route and secure cables properly to avoid strain, bending, or accidental disconnection during operation.
-
Use correct settings: Match material type with proper power/speed settings to avoid overdriving the 4.2W laser.
-
Firmware/software updates: Keep CNC and laser control software updated for improved stability and compatibility.
-
Inspect regularly: Check for lens wear, loose fittings, or misalignment before each production run.
-
Safe storage: When not in use, store in a dry, dust-free environment and protect the laser head from scratches.
