draw circle by stepper motor

[dfaweew]

hello!I have two linear slide，x and y;I am now able to slide straight line uniform motion , but My goal is to draw a circle ，So I need to have an x-axis is the sine or cosine speed changes , but I do not know what kind of impulse needs  to  control sinusoidal motion , some problem like time interval, pulse number , etc.Please give me some advice or help，thanks！

If you can generate the series of XY locations to trace the circle, you are half done. In terms of getting the XY table to draw the circle, it depends on the controller you are using. Many provide the ability to enter X and Y values directly.
