I purchased it in 2018 and it was called “EleksMaker® LA03-2500 445nm 2500mW Blue Laser Module” The link to the item on bangood is no longer valid but when I search for that model I found this EleksMaker LA03-2500 Blue Laser Module With Heat Sink 445nm 2500mW Aircraft Aluminum for CNC DIY Laser Engraver Machine Parts - BeamQus that lists the specs as 2500mW constant laser power. I’ve just found where I purchased it from on banggood. The link to the laser I posted is “similar” to the one I have however like I said I’ve had it for a few years and didn’t remember where I purchased it from. 2500mW Adjustable Focal 445nm Blue-Violet Industrial Engraving Laser Module 12V.ĭescription: 2500mW blue-violet laser engraving machine for high-power modules dot 405nm laser head can focus bottom of the fan cooling design.Enhance heat dissipation, run more smoothly and safely Features: aerospace aluminum shell, heat better.
This is a similar laser diode to what I have. This setup is working however I’d like better grayscale and to be able to adjust laser power through software.Īny suggestions on a driver board or schematic would be greatly appreciated. But now I have it setup on a new machine with Arduino UNO (GRBL 1.1h), CNC Shield V3 and using the same solid state relay attached to the Z+ and Ground pins to enable the laser.
I’ve had this laser for a couple years and ran it off my CNC router’s breakout board through a solid state relay via mach3.
My main objective is to be able to get the laser on PWM and better grayscale. I’m looking for suggestions on how to go about connecting my 2.5W laser diode to an Arduino running GRBL 1.1h with a CNC Shield V3.
