Hi all. I’m 68 and refuse to retire. After eight years in the Air Force and another 40 years running factories, I now teach people how to run factories. I decided to get into laser engraving as a side hustles about a year and a half ago. I wanted to find an income source that allowed me to be home more. My wife has some disability. I started with a K40 and learned a lot. Recently I purchased a Full Spectrum PS-20 (big mistake). RE3 doesn’t hold a candle to Lightburn. So I have refitted the machine with a Ruida DSP. This forum has helped a lot in this endeavor.
