How to control 200 stepper motors simultaneously

I am new in the electrical engineering domain and I know very basic things about the microcontrollers.
I am going to control 200 stepper motors simultaneously using a microcontroller or microcomputer.
I am familiar with python programming and I prefer to work with it.
Could you please help me and let me know what product works best for me!?

is it possible to use a microcontroller (which uses python) and just hock up all stepper motors and run a program to talk with each stepper motors? Is there any easy way to stack microcontrollers so it builds up the potential of connecting more and more stepper motors?

I want each stepper motors to do some steps but it would be different than other steppers. Each stepper motor should step independently and freely based on the values that are come from the Master! I guess I need a 200 GPIO or some tools to be able to operate this for me! do you have any suggestions?

here is an example of a project that I like to do! please check out the link. https://vimeo.com/101408845
Here we see that there are 200 stepper motors that each works independently! a camera takes and input and returns it to steps for each stepper independently! How can I control all of these steppers in a project like this?

I appreciate your help in advance.

Hello @Atashnezhad and welcome to the forum,

If you prefer using python a good option is a Raspberry Pi. However 200 stepper motors and one microcomputer seem unrealistic, you’ll definitely need more than one as well as many motor drivers, to choose the driver you’ll need to know the specs of the motors you’re going to use (voltage/current).

On the other hand, are you sure you need steppers? An alternative would be to use servos and an I2C servo driver, like this one:

Here’s a tutorial if you’re interested

You can even chain up to 62 drivers, check this tutorial for more information
