Features
- 40W Diode Laser Module - K40 is a true 40W+(40000mW ) output laser engraving and cutting module designed for powerful cutting. Built-in eight high-performance fast-axis compression diodes, which can provide up to 44000mW optical power to achieve fast and efficient cutting. LASER TREE laser cutter module can cut 30mm pinewood, 15mm acrylic, and 30mm plywood in one pass. A One-Stop Solution For All Your Machine Upgrades
- Built-in Air Assist & Dual Fan Cooling Design - Built-in air assist improves cutting performance, and reduces air resistance, resulting in faster, deeper, and smoother cutting with fewer burn marks, cutting accuracy and cutting quality can also be optimized to a great extent. Dual fan cooling design, excellent heat dissipation improves laser head stability and service life.
- Wide Compatibility - In order to improve the compatibility with different laser engraver machines, K40 provides a solution by an adapter board for electric compatibility and a sliding bracket with multi holes for installation compatibility. Electric compatibility can be checked easily by 'power' and 'signal' LED indicators. This laser module is compatible with TTL/PWM-controlled DIY machine, laser engraver cutter machine, CNC laser machine, and 3D printer machines
- Detailed design - The bottom is equipped with a red cross positioning cursor (offset X: 0mm, Y: -21mm), which can quickly locate the starting point and ensure the accuracy of the secondary cutting operation. Integrated dovetail guide design ensures smooth movement and stability of the equipment. The focus slider structure has been upgraded to slide more smoothly, allowing users to achieve precise cutting quickly and easily

Size: 40W+ Laser Output
Delivered on time, came very welled packaged, just as seller described. Unit was easy installed on my Longmill cnc. This unit is way more powerful than my 7 watt. Cuts through ply, MDF, Acrylic, and pine as advertised on web site. I may buy their smaller laser just for engraving tile because this one is a little big. I have cut acrylic key chains, words for crafting, engraved plywood,cut 1/4 ply for a prayer cross. I bought the comgrow Air Assist kit to provide air assist.

Just installed this on my Falcon CR10 laser engraver (changed from 10watt setup to the K30 laser head) Definitely using the provided power supply. This unit is for DIY machine setups. The included driver board should take care of any connection you need to get this unit going. For the most part it was plug and play with my setup as far as wiring goes. My challenge was mounting the sliding bracket to my existing frame. The provided bracket has more than enough holes and slots to accompany your existing setup. Personally, I found the M5 screw heads wouldn't fit into the slotted sections and the M4 screw heads that i used to attach would not countersink enough to clear the sliding bracket on the head so there were some slight modifications made to make things work. It would have been nice to have some zip ties and maybe a few random fasteners that would work with the provided hardware. Overall i think i made a good purchase. The blue anodized finish matches the Creality frame which was a bonus. One gripe i have thus far is simply having to turn on/off the laser head separately from the gantry but a power strip handles that for now.

Works like a champ on a CR falcon with some minor modifications to the machine. I had to drill some holes in the machine bracket to accommodate for the new mounting bracket, 3d print a spacer to account for the larger module, and add a switch to turn off the PWM signal entirely when framing a burn job - the framing cross hairs only show when the power is set to 0, but Creality's stock firmware is set to 5, enough to lightly engrave the perimeter on leather or wood with the more powerful module. Make sure to account for the 21mm offset in lightburn if you're sending via Gcode on a sd card, else it'll try going past zero.

The media could not be loaded. Bought this to upgrade my 5.5w sculpfun s9 after being frustrated with it. No special modification needed, it bolted right on. It did need two longer m6 to bolt the adapter plate to that carriage, i had two laying around. This laser cuts very well and deep. I use shop air between 20-40 psi for my air assist and it cleans the cut awesome. Plywood doesn’t cut well due to glue and different woods types. Etched steel. Doesn’t etch aluminum. Good manual in box.

I was part way through a laser project when the XTOOL 10W diode laser failed. Read about this one, and took a chance. I am very impressed with the output of this laser. I can now cut 3mm Basswood in one pass at 60-70% power. Prior, I was making 4 to 5 passes at 100% to cut same 3mm Basswood. It is a little heavier and larger than the XTOOL 10W. However, the frame does seem to support it well.

Will not work on certain models of xtool and they know it. They said they will send the parts to make it work. Waited almost three weeks and got the wrong parts. They then wanted $40 for the parts which would have taken another week which would have put me out of the return window. I returned it.
