Step pin for ATmega328

[MOCmaniac]

I'm doing a project at university where I'm using 3 steppers. Two nema 14 pancakes with a reduction of 7.5 and having to do 2 revolutions per second. I would like to use a microstepping of 8 or 16 (and have this microstepping interpolated up to 256 by a TMC2208). This gives 24000 pulses/second with a microstepping of 8. The third stepper must move at around 1 revolution per second and the microstepping can be much smaller (4 is sufficient -> 800 pulses/second).

I was planning to use an arduino nano for ease. I see that I can only use pins 9 and 10 with this library. Is it possible to connect the 3rd stepper to another pin as the frequency of the pulses is much smaller ?

Otherwise I will use an esp32.

Thanks in advance for your feedback

FastAccelStepper does not support that with the 328p, but you could either use AccelStepper or toggle the third stepper pins from app side with 800 pulses/s.
