I missed the "emulates" and saw pulses and direction.

Nice work!!

I don't own any steppers, I don't know why any of my links would talk
about them. The BLDC link talks about the brushless DC motor
controller; it ∗emulates∗ a stepper by accepting standard step+direction
signals like stepper-based CNC machines use. The firmware counts the
step pulses and rotates the servo motor to the correct position.
