    M140 A-Type vs M-Type

    Do they provide different output power at the same amperage, or is the M-Type just capable of accepting higher amperages? It will be mounted on the print head and power controlled through a pwm supply that normally controls a fan. I had it working, but burnt up the diode when I miswired a new...

    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...

    Check my CNC Etcher Setup

    I finished mounting my laser to my CNC etching head the other day. I'm highly impressed with the output power and didn't notice any heat buildup with the short test runs I did. For now the fan is just sitting behind the module/plate, but I'm going to mount it to another aluminum plate and I'll...

    SpiderSpartan: Destroyer of Lasers

    Thanks again for the tips. I now have a functional 250mW, handheld red pointer, and my 1.8W blue etching head. I'm updating my etching CNC build here.

    SpiderSpartan: Destroyer of Lasers

    Thanks for the tips. I have a 12mm, finned aluminum heat sink that I will be mounting to the backplate to hold the diode module. I also have the parts to build a test load, that I will use before connecting the diode to my driver. I picked up an anti-static wrist strap from my local pc store...

    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

    Awesome. Thanks for the suggestion. I will update as I build here.

    Check my CNC Etcher Setup

    I actually did. He just doesn't have all the test images on his site from what I can tell. Thanks. Any recommended duty cycle for the M140 diode using the specified heat sink at 1.25 Amps?

    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...

    250mW 650nm laser review

    Not to hijack a dead thread, but any recommendations for wavelength/color and power to burn black spray paint off a copper board?

    250mW 650nm laser review

    I know this post is over a year old, but I just bought one of these laser setups myself and I'm wondering does it have enough power to burn stuff? I'm hoping to use it on my cnc machine to remove PCB etch block.
