GET YOUR CO2 LASER UP AND RUNNING QUICKLY...
IT'S AS EASY AS 1-2-3!
Welcome to one of the most complete on-line resources for inexpensive CO2 laser engravers, commonly known as, Chinese Lasers. This site is geared towards CO2 cabinet lasers, rated for 50 watts or more, sold under the OMTech and Preenex names, but owners of HL-Yeah and other brands should find portions of this site of use as well.
Shortly after I ordered my CO2 Laser Engraver, I discovered that there were many modifications that needed to be made in order to have a reliable and quality machine. However, what I found was the information to modify them was fragmented, conflicting, hard to find, or simply didn't exist. I took notes on the modifications I made to my machine, so I would have them for reference. Later, I realized I wasn't the only one who has having a difficult time finding this information, so I typed them up and posted them on my personal web site. That single page document has since grown into this large web site. On this site, I have compiled a list of components, documents, and videos that I have found useful for purchasing, setting up, and troubleshooting my Preenex laser. My hope is that you will find this information as useful as I have.
Please note that I am a hobbyist when it comes to these machines, and not a trained professional. Therefore, the information below is what I believe is the best way to do things, and may not always be the best, or in some cases, the correct way to do them. Use at your own risk.
