Not quite sure what your saying here Boyan.? . . . . Are you trying to say this isn't achievable with steppers.? Because if so then your very wrong.!
Just about every machine I build will or should say is designed to achieve these speeds or very close to them. Some Smaller machines will achieve well in excess of 10mtr/min and 1500mm/s/s.
Don't actually run them or tune them at those speeds for reliabilty reasons but they will do it if required.

I find above 2000/s/s gives negative affect to machine as it's far too jerky on short moves leading to poorer surface finishes.
