I bought this laser to upgrade my Nasum A5 Pro, whose puny 5W laser required two passes to cut 3mm basswood. The box contains the laser unit itself, a sliding mounting plate in two parts (one attaches to the carriage, the other to the laser head, a few screws with matching hex wrenches, a power adapter board with cable, a few acrylic focus spacers, and a replacement lens. Attaching the mounting plate to the Nasum carriage would not have been possible without reusing two screws from the previous mounting plate; as it is I could have used two more. I would have appreciated finding the corresponding screws in the box. Two thumbscrews secure the laser plate to the carriage holder and allow for easy focus adjustment, this is very handy. There are two versions of the laser head on this page, 12V and 24V. They look identical, apparently the 24V version see a lot of returns, probably because most controllers on inexpensive engraving tables feed 12V to the laser head. The included voltage adapter can be used to convert 12V into 24 or vice versa if needed, of course at the expense of another board and more wires -- so make sure you check the voltage and pinout on your controller before ordering. The Nasum A5 Pro uses the same connector and 12V, so it was an easy replacement and I don't need to use the adapter board (I could have done with a cheaper version WITHOUT the board, and maybe with a couple more screws instead!) The hose of my air assist pump connected easily to to the brass nozzle and it works great. Finally, the optical protection attaches magnetically to the bottom of the unit. Overall, install took roughly 15 minutes, easy peasy. I ran a few tests and it essentially cuts twice as fast as the original 5W laser: card stock cuts at 2000mm/minute at 50% (instead of 1000mm/m at 50% with the 5W) and the edges are perfect; basswood cuts in a single pass at 200mm/m at 100% instead of requiring two passes at the same speed with the 5W. So, a very worthy upgrade I'm very pleased with.

This little guy has plenty of power for engraving on things like paper and solid color woods but really struggles with b Common bamboo cutting boards. This isn't the fault of the laser quality as the unit is nice and solid feeling and the bolt pattern makes it easy to install. It just is what it is and limited by being a diode laser. Even with air assistant cutting solid cardstock is painstakingly slow and not worth doing.

Plug and play on my ortur lm2 pro. Replaced the 5.5w laser. I was able to increase my cutting speed and made more materials available for use.

This doubled the laser power of my AtomStack A5 Pro. Lasertree provided instructions for installation and use. They also provided focusing shims in 3, 4 and 5 mm so the laser can be focused based on material thickness and operation (cut vs engrave). The installation was a breeze, though I did have to remove my z axis adjuster. Everything else was a straight bolt-up. I did place the driver board atop the x axis carriage using double sided foam tape,

Doesn’t fit Ortur 2 bed. See pics, the needed additional bracket for the laser make it hit the rail and strips the belt until you unplug it:/. I’m sure with major modification it would work, just not really an easy convert. Laser itself, great as a true 10w laser. I was able to etch glass, burn a crisp picture. So laser awesome and did plug right in. I ended up getting a different one.
