Hello Everyone,
I am newbie to accelstepper library and stepper motors.
I am using accelstepper to run two stepper motor with a custom hardware in which the enable pin of both the motor are shorted in PCB trace.
So if I enable any one motor, other motor is enabled automatically.
Since the motor at very high speed has torque almost zero, Is there any way to disable one motor (more specifically reduce torque to zero) using some speed or velocity settings and without changing
the hardware?

I can't see how this is related to the problem you are trying to solve.

If you don't tell the stepper to step, it won't move on its own accord. So, I don't understand the problem you are trying to solve.
Steppers have to be powered down for zero torque, since they have a shared enable pin this isn't possible,
clearly...

When enable pin goes LOW, the stepper motor is enabled (cannot rotate, remain standstill position: Meaning cannot be rotated freely by bare hand, here free movement refers to movement when motor is not powered).
Since, the stepper motor share same enable pins, as soon as enable pin is LOW, both motor are enabled (no free rotation), I want to enable one motor and disable other one. If performing hardware changes (separate enable pin) is not an option, then is there any other way to achieve the same?
I've answered that question already.
