I have one of those cheap 300-400 dollar 40w ebay lasers. Not sure where my disk ran off too, does anyone have one that are willing to share the files?
I spent part of the annual period in China for years working for my primary customer in molding and prototyping. After studying cricut vs silhuette reviews. In my facility in Zuhai, I have a 20-150W CO2 laser cutting room, some of which are very elderly and have been in service for ten years or more. They are not noobs. They are not noobs. They use a large , heavy storage tank system to run the tube coolant on the atmosphere, around 80-85F for southern China. After years of storing time and tube life study they went to the ambient system, dumped their chillers and concluded that the delta was not adequate to justify the cost of the chillers. I know that their main competitor often uses a large supply in the environment.
