Easy to Assemble --- Small and compact, Carving Material ---Wood, paper, leather, bamboo, plastic, rubber, alumina, stainless steel, etc. This laser module is suitable for all machines or control boards with PWM signal control. Please refer to the manual or contact LASER TREE if you have any questions about the connection. Note: Regular cleaning and maintenance of the lenses will maintain good cutting results and obtain a longer service life. LT-20W-A Specifications FAQ： Q: Input not matching our unit? A: Our module interface is an XH 2.54 3-pin connector. Please refer to the product images for the specific layout before purchase.If you are unsure whether you can connect, please cont/act us for assistance. Q: When the laser module is connected, the fan runs but the laser is not on. Solution 1: Please check if the signal port (PWM) is well-matched. If you are not sure which port on the main board is "PWM", please check with the main board seller. Solution 2: Power off the engraving machine; Disconnect the cable of our laser module from the main board; Reconnect the laser head to the main board and restart your engraving machine. Q: Is this laser module compatible with CNC machines? A: It can be used with a CNC machine attached. But the size does not fit the original bracket of the cnc machine, you need to make or buy the bracket. Review: Perfect Review: Great small 4 watt laser but does not use a std m9 -.5 thread - This is a great little laser, 35X35 mm, but it delivers every bit of 4 watts of optical power. Hard to beat for this price. It can easily burn pine at 500 mm/ min with 35% power. It can cut thourgh chip board (like a cereal box) at 100 mm/ min. I have not tried to cut plywood, but it should be able to handle 1/8 inch at 100 m,/min full power. It is defintately not strong enough to engrave on any raw metel. I have tried aluminum and ss. no impact even at 20mm/min and 100% power. One negative is that the lens barrel is 10 mm instead of the standard M9 .5pitch. Even though you can change the focal length (by turning the lens), I could not get it to focus under 24 mm. The lense can be removed, but it is an odd size. It appears to be an m10 .5 pitch threads. ## Features - 【Laser Module】4W (4000mW) optical laser power output. Line width is narrower and suitable for ordinary plywood; Adjustable laser head(Adjustable focus: 20mm - 50mm), easy to adjust, ensures engraving with good quality and high efficiency. 4000 mW optical laser module can cut through 1-2mm Plywood in one pass. Class level: Class 1 - 【Original Diode with FAC】The Blue Laser module with original diode, high stability, high efficiency, and high quality. Bright blue-violet light, easy to locate when engraving. Adjustable focus laser head suitable for DIY engraving machine, three-axis engraving machine, upgrade or replacement, easy to install. - 【Eay to Assemble】This diode laser module is small, compact, convenient, and easy to install. Size: 35*35*99.6mm. Wavelength: 450nm; Input: DC 12V 1.6A(1.4-1.8A); Power adjustable: Support 5V PWM modulation; Input port: XH2.54-3P socket; control line installation method: pluggable. Package include: 1*laser module, 1* 3pin cable - 【Widely Use Materials】The laser engraving module can be used to engrave MDF, wood, paper, leather, bamboo, plastic, rubber, alumina, stainless steel, etc. (🔺Unable to engrave with blue/purple/white/transparent material, aluminum without oxide layer) Note🔺: Please wear appropriate safety glasses when using the laser module to prevent laser light, even any reflections from entering the eye - 【Comprehensive & Trustworthy After-Sales Service】Our modules are suitable for PWM signal controlled laser engraver laser cutter machines, cnc machines and 3D printers and so on. But due to the many brands and models of machines, not all of them can be plug and play.

Also can set the same table up for CNC Oxy/Fuel cutting as well. Even are options to swap out the plasma cutter for a router to carve and cut wood as well, some have digital hight control to cut uneven material like diamond plate or corrugated steel. And there are options for cutting pipe as well. Many people have made there own and yiu can buy units as small as 2'x2' table cut size or up to 4'x8' and even bigger than that. Some have nesting software that will arrange all of your cuts ro use the least amount of material. And say you have a 4'x4' table but need to cut a 4x8 or bigger sheet of steel, you can cut 4' then slide the steel so it can get the remaining 4 feet and so on. A plasma cutter than can cut 1/2" steel plate cleanly will not cost thst much but I personally would get something that can cut up to 3/4" (or even 7/8" to 1") cleanly. Do not get a machine that can barely do 1/2" or you will be cutting slow and maxing the machine out possibly using more consumables and not having a clean cut (if your looking at lasers I assume you want a clean cut, even by hand using guide steel to run up against I can produce some very clean plasma cuts and CNC can do even better). Dont look at the sever capacity only look at the clean cut capacity and get it slightly oversized. If you want a cleaner cut than CNC plasma can do and any dressing of the material after the cut isnt an option then if you can afford it look into waterjet tables over laser. A benefit of waterjet over plasma is not having thr heat that is associated with cnc plasma or CNC oxy/fuel. I have used hand crank devices that attach to large well casing via a chain and you jabe an adjustable oxy/fuel torch head. You line it up have the large 24" or 30" casing on rollers and you slowly rotate the handle to roll the torch around while rotating the casing in rollers and with this I have seen very impressive smooth and beveled cuts. So CNC plasma will suffice for 90% or more of people out there! **Q: Le queda ala máquina atomtrack?** A: Yes **Q: I cannot find any documentation on this module. Does it need a laser driver? Do you have any links to documents or recommendations?** A: Hi friend, Thanks for your question. Please send us the control board of your laser machine directly and contact us. We will give you the appropriate connection. The reason different customers have different control board and operation software,so it may have some different operation mode ,we can not give a same manual. Hope you can understand. Have a good day! **Q: Can I attach to Twotrees ts-55 engraving machine?** A: Yes, you can attach it to Twotrees ts-55 engraving machine ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect *by S***K on 26 January 2026* ### ⭐⭐⭐⭐⭐ Great small 4 watt laser but does not use a std m9 -.5 thread *by J***E on 24 July 2025* This is a great little laser, 35X35 mm, but it delivers every bit of 4 watts of optical power.
