This looks interesting...

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?,

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
