HI all,
I am trying to Use an Arduino Uno to control two stepper motors which are connected to 2 linear stages. I can set x,y coordinates of the desired points and it works pretty well. However, when I try to use it to draw a curved pattern (say an oval) it makes the path, but the path is not smooth. I was thinking of using of 2 Arduino rather than 1 and write a parallel code for each stage separatly. But before putting an effort on that, I'd like to hear your opinion about this case. I know in many places people are using rotational stage rather than linear one to make a circular path, but I believe by setting the 2 stages to go over a smooth sinusoidal pattern, I can get a circle.
Thanks,
Saridar
