If you need manuals or support for Amada machines, remember that Amada’s Service group (at least, the one here in California) is pretty good. I have gotten advice and PDF manuals from them, and they will also suggest alternate resources (service techs and others) when they aren’t able to help directly.
Here are some links to resources for lasers, machines, and controls.
Laser engineering Forum at Eng-Tips
(A number of capable laser techs frequent Eng-Tips, so there is good info and you can also find a good tech if you need one)
