This part is all about Laser theory and safety issues .
Just wanted to step by and say thank you very much for your videos and the transfer of your knowledge that happens when watching them. Some great new aspects that i haven’t been thinking about yet like the reflectivity.
Thank you so much for a brilliant and very informative video. I have been researching these machines for some time and many unanswered questions have been addressed in your videos. The Machine you have is the model I have been looking at, how are you finding its performance. Thanks again.
