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 ### ⭐⭐⭐⭐⭐ Review *by J***E on July 24, 2025* ### ⭐⭐⭐⭐⭐ Review *by K***E on April 23, 2022* ### ⭐⭐⭐⭐ Review *by A***R on April 23, 2026* ## Frequently Bought Together - LASER TREE Laser Engraver Module, 4000mW Optical Power, Laser Engraving Cutting Module, Adjustable Focal, 450nm Laser Head for Laser Engraver Cutter Machine DIY Wood Paper Leather, Class 4 - FreeMascot IPL 200nm-2000nm Laser Safety Glasses for Laser Hair Removal Treatment and Laser Cosmetology Operator Eye Protection with Case (Green) - FreeMascot OD 4+ 190nm-550nm Wavelength Laser Safety Glasses for Typical 405nm, 445nm, 450nm,520nm,532nm Laser Light for Hair Removal Laser Treatment Eye Protection Goggles (Red) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/361402347-laser-tree-4000mw-laser-engraver-module-450nm-adjustable-focal-laser](https://www.desertcart.vu/products/361402347-laser-tree-4000mw-laser-engraver-module-450nm-adjustable-focal-laser) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
