I’m looking at going back to school to pick up something else. CNC is something I will look into. Other ideas are electronics maintenance/repair and industrial robotics.

My son is finishing up electronics thru the local community college. It's an accelerated coarse in partnership with the local mines. He has a high paying job as soon as he's done.

good for you!

electronics anymore is more of a troubleshooting position that will require basic electronics theory/classes with electronic testing equipment, with FRU's "field replaceable units" as the normal repair part of the position and problems are usually fairly easy to trace, unless you are talking about trouble shooting/repairing boards that is

robotics, unless you are coding them, will require classes again in electronics using testing equipment and pneumatics theory/class again mostly with FRU's as the normal repair function

CNC on the other hand, unless using CAD and writing programs, will be more involved and cover all aspects of machining technology as you will need to learn at minimum, metals/speed&feeds and cutting/turning/milling/drilling/grinding/EDM/ECM machining theory to be able to set up, run and tear down jobs

best of luck
