Is the F in FEA really an abbreviation of Finite, or does it mean something else here?
Is this Mechanical Under-Engineering at it's finitest?
I still think it's a great idea for learning on foam and possibly balsa, if it's significantly cheaper than other inadequately engineered desktop CNC machines it will be less loss when it's passed on cheap or scrapped in favour of something almost competent,
