Building on what John said... CNC is one part of my regular job in commercial lighting controls-I use it mostly for custom faceplates and enclosures. In commercial lighting it is not uncommon for people with no training in electricity or control theory to be responsible for complex systems. Manufacturers compensate for this with better integration and user interfaces. This means that techniques developed for the most demanding applications are available for the low end as well. I see the same process in EMC-the features that are useful for the large industrial user or integrator may never be used by the hobbyist, unless they want to tweak things. But that does not in any way mean that the hobbyist should be excluded-some of those hobbysts will be the next generation of CNC professionals, or their kids will.
