Hey!
An example:
The speed = 300steps/s and acceleration = 100steps/s^2 with
- 1.8 deg/step stepper motor
- full step
- gear ratio 54
means speed = 10deg/s and acceleration = 3.3deg/s^2 according to this function.
In your setup you want to achieve the same speed and acceleration (10deg/s and 3.3deg/s^2) but with different gear ratio.
