In the “G-Codes for Amada Lasers” page, there was some discussion of training.
I can offer some training and troubleshooting on these older machines.
I am located in the Los Angeles area. I worked with lasers at Amada until about 2000, so I had some familiarity with the 160-IL and earlier controls.
But Amada and others can train on 16 and 160 controls. They may not support the older ones, and I can.
