I use to work for Amada for 7 years. Last January I started my own laser repair, install, training business. I've never worked on the Spectra Physics, But I have worked on PRC and FANUC types of laser that come with Amada machines.
One of my customers with the same machine as what you have. Next month I have a training class with Rofin to fix up their laser. We could wait till after that or I could just figure it out with Amada and Rofin phone support.
I have a B.S. in Mechanical Engineering and almost ten years laser experience. Give me a call. 503-752-6121
