This kit is compatible with almost any 3D printer and CNC available in the market as the Makerbot Replicator 2 & 2X, Ultimaker 1 & 2, Shapeoko 2, X-Carve, etc. Check this page to see how to install the kit in different printers.
The kits gives you a bunch of features that makes it 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. It was also manufactured with safety in mind! 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 new safety features to protect yourself and others:
This kit is a combination of the new 2.8W 445nm 9mm Laser Diode Component and the 2.5 Amp matching safety compliant laser driver kit with a 12V adapter. We now include a pair of safety goggles with every kit as well! This has everything you need to get your laser up and running in your product or project. The kit includes:
This is the bigger 445nm 9mm laser diode with an added very high quality G2 optic lens with 30% higher efficiency than our traditional three element glass lens! It has way more power than the 1.7W laser we have been offering. The difference is that this bad boy can run for extended times at 2.2W at 1.7amps! This laser has a maximum limit of over 2.8W 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. The spot size is a bit bigger, so very small engraving will be a bit more difficult, but the trade-off in more optical power on the work surface is worth it. This laser is very effective and can run for extended times in the 1.3amp to 1.7amp range and we recommend not going much over 2 amps for extended periods of “on time”. 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 aluminium housing and has an aluminium 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 2.8W 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. 1.7 amp at 2.2W will allow for longer “on” times and will not degrade the laser as quickly. Thermal issues are the number one reason for catastrophic failure of the laser. While the mounting case provides heat sinking capability for the laser diode, it is up to the consumer to make sure the laser is operating effectively within these limits.

This is the fourth 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.
