Description

Upgrade your Maslow to laser engrave!

THIS KIT REQUIRES AN EXISTING MASLOW FRAME TO OPERATE

A stand-alone laser kit is coming soon! 

Included in this kit:

We highly recommend having a separate sled for engraving!

The laser is mounted directly to your sled with a 3D printed mount, reattaching your mount over time will strip the wood holes needed to hold the mount in the center of your sled. Having a separate sled means to engrave, you just have to swap your CNC sled for the one with the laser!

We also recommend creating Gcode with Lightburn ($40, not included). You can download a free trial here.

Frequently Asked Questions

Yes, the laser will work with the Basic Maslow sled, as long as you have a DUE board installed. Purchase the Maslow kit here.

Lightburn and Makerverse. You will need Lightburn (GRBL-based version) to make the CAM file. you can purchase it for $40.  You can then import the G-Code into Makerverse to run on the CNC. Ensure that you are using Makerverse version 1.2.0. You will need to use the same login credentials for the laser widget that you use for CNC in Makerverse.

During operation, please avoid direct exposure to the beam. When choosing the material to cut,  please refer to the safety disclaimer and choose the proper materials. Please pay extra attention in choosing the right plastic to cut, as many plastics will melt, catch fire, or create very toxic fumes!

Depending on specific laser, the laser can potentially engrave or cut acrylic, paper stock, wood, glass, aluminum, foam board, leather, circut boards, some plastics (NEVER vinyl!), fiberglass, carbon fiber, etc.

The cutting/engraving depth varies depending on the power intensity of the laser and the material you are cutting/engraving. The depth can range from 4 inches on foam, to 1/8 inch on balsawood.  Density, color, and thickness of material will affect results. Multiple or front & back passes may be required to achieve your desired depth.

All design files in SVG format can be transformed into a CAM file in Lightburn, and processed in Makerverse for laser cutting.

No, there is no additional calibration needed for the laser. If you’re calibrated for the router, you’re calibrated for the laser!

J Tech Laser Information

6th Generation Product – it just keeps getting better!

We have spent thousands of hours engineering the best laser product on the market for industrial, enthusiast, and research applications. It is now here.

We have re-designed the product to improve safety, stability, power, and more cutting ability. We have tested the laser for continuous use at full power for more than 5 days straight of use in normal operating conditions.

We have gone through many generations of the design to get to the best of the best.  We have performed extensive thermal imaging and thermal analysis to get to a stable output at high power.

Our new interlock system is totally re-designed to give optimal performance and safety you can depend on with extra features and more transient suppression. The isolated inputs are now even more industrial as well.

More TRUE Power, More Safety, Quality Engineered Design

-Because it is running at 7W, the lifespan will be diminished.   Running it at lower current will increase the lifespan.

This is the bigger 445nm 9mm laser diode with an added our High Efficiency AR Coated Glass lens.   This laser can run for extended times at 2.2W at 1.5amps!  This laser has a maximum limit of over 3W at 2.5amps and should only be over-driven like this for very short times.   This level of power certainly creates the ability to cut more and do more with your laser.   At the factory setting of 1.5amps @ 2.2W you should get about over 3000 hours of lifetime from the laser.  This laser also has internal ESD device for an extra level of static protection.

This multi transverse mode laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink.  The laser is set in the heat sink with thermally conductive paste.  The front of the component contains a adjustable glass focusing lens for the laser output.  The laser has an ABSOLUTE MAXIMUM of over 3W at 2.5amps and should only be run at this level for very short times.  Additional cooling techniques would be advisable if you want to run for extended periods at higher powers.

We have kept all of the features that make this laser kit awesome – 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.  But NOW we have more safety in mind as well!  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!  Here is a run down of the safety features to protect yourself and others:

  • Key Switch – This 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 switches to your enclosure so when it is open, the laser will automatically turn off.  Also provides for the addition of an E Stop button for the laser, which is always good for if you need to stop the laser super quick!  Add as many switches as you want to make a super safe area for your laser machine so nobody can accidentally look into the laser.
  • Power Fault Protection – This one may seem like it is not needed, but hear us out.  Consider your power goes out in your area where the laser is located.  You were running your program and then everything is dark…  Power doesn’t come back on for awhile… long enough for you to forget that the laser was left ON!  You come back and are checking your laser and boom, the power is back on, right when you are looking straight at it.  Well, don’t worry because the laser will be disabled whenever the power to the driver is lost.  Press the reset button and you are back in action!
  • Emission Indicator –  The small little LED on the front to let you know  your really super bright laser is on…  They require this in case you are using an infrared invisible laser.

This is the fifth generation of the popular High Current Laser Diode Driver series.  We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation.  This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators.  All of these features make for a safer laser operation and will comply with federal laws regulating such operations.

At the heart of the product are laser trimmed parallel regulators to give constant current without the large temperature dissipation of other regulators. Couple this with inherent safety features like soft starting, current isolation, reverse protection, ESD protection, and thermal shutdown control and you have all you need in a small package.

The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products.  The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics.  This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops.   The board has screw terminal connections as well as Molex mini-fit Jr. connectors for easy connections to external equipment for control and the laser diode output.
