You'd be amazed how much horsepower an h8 has..
But, it probably also has some motion control chip.
St has really nice stepper motor comtrollers. You can set acceleration , decelration , torque curves , and much more. Big whoppin tqfp with 80 pins.
And ot has i terface for a quadrature encoder so it will close the loop.
Aal the professional machinery, pick place, lathes , cnc, robots, waferhandlers , uses feedback from encoders. There is a reason for that.
Encoders don't really cost much.
