I used an Arduino Uno with A4988 driver with 1/16 microstepping and tried to achive the highest speed possible. Using AccelStepper library
the speed was not satisfying. I got smoother and also slower result with DRV8825 and lv8729. In the AccelStepper library help it says:
The maximum speed achievable depends on your processor and clock speed.
I was expecting to have a 7 times faster performance BUT unfortunately I get the same result as I got with Uno and Mega.
How can I have at least 5 times faster performance while using microstepping?
