It was packaged very well thick cardboard and foam. I haven't turned it on yet I still need to setup ventilation and water system. Everything appears to be in good condition no damage. I will update after I start using it but I wanted to put some pictures on here. Just incase someone else is like me and searching everywhere to see if bottom was already cut out for larger rotary or not for some reason omtech doesn't show this in any pictures I've seen. I am happy to see it is pre cut unlike the original k40. ### ⭐⭐⭐⭐⭐ Awesome choice *by on Reviewed in the United States May 16, 2026* Love love love it!! At first I was having problems since it was my first time but it cuts and engrave perfectly!! The only thing is that the usb cable I recibe had to change it since I have to be searching for the laser every time I used it cause it was not connecting properly. But then everything works fine ### ⭐⭐ May collect Dust huge learning Curve *by on Reviewed in the United States December 17, 2025* May collect dust tried 3 different laptops and none of them work hopefully the thinkpad i had to order will work . ## Frequently Bought Together - OMTech 45W CO2 Laser Engraver with LightBurn, 12"x8" Desktop Laser Engraving Cutting Machine for Home Use, LaserGRBL Compatible, Air Assist & Adjustable Head for Wood, Glass & More - OMTech CO2 Laser Coolant Non Conductive Liquid Cooler Heat Transfer Fluid for Laser Engraver Water Chiller, Prediluted Antifreeze Coolant for Laser Tubes, 1 gal Blue Transparent Water Cooling Solution - OMTECH 9L Industrial Water Chiller 2.6gpm CW-3000 Water Cooler for 40W K40 CO2 Laser Engraving & Cutting Machines, Water Cooling System Radiates 50W of Heat per Degree C --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/722745079-k40-45w-co2-laser-engraver-and-cutter-with-lightburn-12](https://www.desertcart.kg/products/722745079-k40-45w-co2-laser-engraver-and-cutter-with-lightburn-12) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-17*
