One of the downsides of computer aided design - everything is cut down to the bare bones limits that can theoretically take the needed stresses and wear, to allow machines to be sold cheaper. After a few years of mass-production use, every moving part is worn out and the cost to rebuild is near than of a replacement! The older machines are built more on rule of thumb and "brick outhouse" principles and can be maintained just about forever, or at least be upgraded with newer, decent control gear. The electronic were the same; a common 1970s-80s servo drive type, rated around 25-35A, was fused at 160A as standard! Modern ones either trip out or leak smoke if they much exceed the nominal rating for more than fractions of a second. -
