@TravisGood does an amazing job of demonstrating the parts of Lightburn you could be missing. This is a great opportunity to learn in a low stress environment.
I am sad to be missing this. I learned more about lasers from an hour spent with Travis in the laser room last fall than from my first two years of making mistakes on laser projects after taking the big lasers class. Travis is an amazing resource that asmbly needs to make better use of.
