    M140 A-Type vs M-Type

    I just purchased a new laser diode to replace one I burned up by providing too much power I think. I have a 1.25A constant current driver that, along with the diode, will be mounted on my 3D printer to do some simple etching/burning occasionally. Since I'm only supplying 1.25A does it make any...

    SpiderSpartan: Destroyer of Lasers

    So far I've: $8-Broken the leads off of a 150mW, 405nm diode (diode is probably still good if I can rig some leads back on it somehow) $16-Burnt up a 150mW, 405nm diode or AixiZ driver board for 650nm and up diodes driver board (It lights up, but has a sort of halo output and no burning power...

    Check my CNC Etcher Setup

    I'm working on building a CNC machine to burn away spray paint on a copper board. I know it's been done and there are posts all over about it, but was hoping I could get some feedback on my planned setup. - I've got an M140 diode in copper module with the Aixiz glass lens on the way from...
