If you want a responsive program with the standard Stepper library you need to get it to move one step at a time and use your own code to create the step timing. That means that you can interrupt a movement - for example when a switch is triggered. The much more capable AccelStepper library can do non-blocking moves with its run() and runSpeed() functions. I wonder if that properly describes the problem? I suspect what is wanted is to get the motor to move in the other direction, away from the switch, even though the switch is pressed.Īlso, I suspect that the standard Stepper library is not suitable for what you want because stepper.step() is a blocking move that runs until the number of steps has been completed.

What is the current permitted in the motor coils and have you adjusted the current limit on your stepper driver to match it? If you need more advice post a link to the datasheet for your stepper motor and tell us what stepper driver you are using. It is normal for stepper motors to be hot. Stepper myStepper(stepsPerRevolution, 2,5) initialize the stepper library on pins 8 through 11:

#include Ĭonst int stepsPerRevolution = 200 // change this to fit the number of steps per revolution The distance is always changing between the limit switch. Is there a better solution to disable the motor? Stepps do not matter in this setup. How do get out of the if logic to allow the motor to start back when the switch is not pushed?Ĭode works to stop the motor but does not turn back on if switch is released. (basic limit switch NO) The switch turns off the motor by. I have a stepper motor that runs until it hits a switch.
