Im trying to figure out how the AccelStepper works and how I can tell my Arduino to move the stepper to one position then a different position etc. The plateau is being moved by the stepper in my case a Nema 17 with a Polulu DRV8825 driver. Accelstepper home position.
Accelstepper Home Position, The SpeedStepper library lets you change the set motor speed and then acceleratesdecelerates to the new set speed using the same algorithm as AccelStepper library. Im fairly new to the arduino platform and the accelStepper library. It is perfectly adequate for simple single motor applications. The curent position can be altered for instance after initialization positioning.
Homing With The Accelstepper Library And A Limit Switch Youtube From youtube.com
In this Arduino Stepper motor tutorial we use the Accelstepper library to demonstrate stepper motor acceleration rate control. Negative positions are anticlockwise. Positive positions are clockwise from the initial position. The current position can be altered for instance after initialization positioning.
The motor starts off slow and then builds up speed as it proceeds just use and empty line to stop it.

To get a stepper motor to move to the HOME or ZERO position you need to move it one step at a time until it triggers the switch that identifies the HOME position. The title of the post is is there a way to bring a stepper to the same start position at startup I didnt really look at info in the thread but to answer the question from the title of the post Id suggest looking into the Arduino EEPROM. If the motor stalls or is oversped AccelStepper will not have a correct idea of where the motor really is since there is no. In most cases the limit switch marks a point very near or at a physical limitation where the stepper cannot proceed and will hit some kind of wall. Arduino Library AccelStepper.
