control stepper motor with microcontroller

meenusaini

hello everyone

i have to draw circle pattern with two stepper motor with microcontroller. can anybody have any idea..

 

 

thank you

  • Build an X-Y stage with a stepper motor driving each axis.

    Put a pen suspended above the center with a solenoid for up or down movement.

    Put a piece of paper on the X-Y stage.

    Set up your MCU to drive the stage using g-code.

    Use Open SCAD to create you g-code.

    Load g-code into the MCU.

    Execute the g-code.

     

    Circle drawn.

    @DAB You shouldn't need g-code - just some trigonometry and knowledge of on in-built timers on your microcontroller. Of course - this is if you will only ever want to do circles.

     

     

    There is of course the question as to why the OP want to draw circles using a microcontroller and stepper motor in the first place.

    • If you just need to draw circles, then there are certainly easier and better ways - for instance, a geared motor and a pen on an arm
    • If it's because this is a student assignment, then I'd suggest you start from your coursework and ask if you're stuck on something specific.
