Although I have managed to condition the output laser beam so that its original diameter and intensity are projected into the work area, the amazing cutting potential have not been realized. I accidentally discovered that it does fantastic things for engraving provided i use a compound lens but that was not my objective. This session is all about trying to decode why that super high intensity is not being amplified as it passes through a lens.

$Buying Your First Laser Machine This is not a machine comparison video thats helps you choose the best machine. No, this honestly discusses the key points to look for in your new purchase and all the dishonest marketing and sub standard products that are being sold. At the budget end of the market , any machine you buy from flea bay will be built from many B grade components. The machine will work in some way but as a naive newcomer to the technology it is likely that you will be blaming your lack of technical prowess for the poor results you achieve. You have nothing to compare it with and it is the fascination of owning a super high tech LASER machine that is being exploited by the Chinese as they sell you a sub standard version of your dream. Dont assume this is a total scam because if you choose the right basic mechanics, despite the substandard main components, you are getting a basic CNC machine at a bargain price. Add about 25% of the purchase price for a new tube and spend some time setting the machine properly and you will finish up with a reliable piece of kit for a fraction of the price you will pay for a supported plug and play machine imported via a third party local company. Here, the facts about the industry are laid bare and I hope this will help you negotiate the purchasing minefield you are just about to enter. It is really a matter of choosing the least worst. I have had 6 years of amazing fun from this technology even though I admit to being one of those naive dreamers when I bought my first mahine.$
