Methods and devices for controlling stepper motors

A method for controller a stepper motor, comprising:

• accessing an existing information set in a microcontroller for a stepper motor, the existing information set defining a first acceleration profile of the stepper motor and a first deceleration profile of the stepper motor;
• creating a new information set that defines a second acceleration profile of the stepper motor and a second deceleration profile of the stepper motor, and
• creating a third profile, using the new information set and one or more holdcounts, that is substantially the same as either the first acceleration profile or the first deceleration profile.

A method for controlling a stepper motor, comprising:

• directing the stepper motor such that the stepper motor follows an acceleration profile, the following occurring after the stepper motor begins, but before the stepper motor completes, an earlier acceleration profile or an earlier deceleration profile.

A computer readable medium comprising machine readable instructions for:

• directing a stepper motor such that the stepper motor follows an acceleration profile, the following occurring after the stepper motor begins, but before the stepper motor completes, an earlier acceleration profile or an earlier deceleration profile.

A stepper motor controller comprising:

• a circuit configured to:
• direct a stepper motor such that the stepper motor follows an acceleration profile, the following occurring after the stepper motor begins, but before the stepper motor completes, an earlier acceleration or deceleration profile.

A method for controlling a stepper motor, comprising:

• directing the stepper motor such that the stepper motor follows an acceleration or deceleration profile, the following occurring after the stepper motor begins, but before the stepper motor completes, an earlier acceleration profile or an earlier deceleration profile;
• where the second acceleration profile and the second deceleration profile are capable of being non-linear.
