Greetings, I am 45 years old and a senior in the Mechatronics BS program at ECPI at the Greensboro campus. I am currently gathering the materials to convert a table top CNC machine into a laser etcher for my senior project. I would really love to get into the custom laser pointer hobby. I have a 5W 445nm pointer on the way which I will use as the burner for my project. I look forward to learning from the wealth of information contained in this forum.
