6 years ago yes we have that.
mine is not efficient now, because its not using hardware timer, but if you have a 32bit processor, then it will be very fast (ESP8266,STM32).
Step rate, i cannot measure, dont have simulavr yet.
but from rough calculation, each step need at least 50-60us on Nano 328p and less than 10us in STM32
But since its not using timer, then its not trigger timer on exact time.
It use a loop and micros() to check if time to do the stepping.
If you want to try, i will be very happy help
I didn't know you were working on this... Looks pretty interesting... I think I'll give might give it a try... And you implemented different acceleration s for G0 and G1 moves, which is useful. How does the efficiency compare to teacup? What type of step rate can you achieve?,
