hi i want to control 3 nema-17 steppers using arduino,i want to use matlab for the coding. i used a normal cnc shield with a microstepping module a4988.
i followed the tutorial in the mathworks-arduino page,but it did not work.
error message i got was:the 'addOnShield' is not specified,something like that.
pls suggest me the what cnc shield should i use and the microstepping driver i need to use and pls provide their model number or bestbuy links.
thanks.

I assume that you have already installed the hardware support package- ‘’MATLAB Support Package for Arduino Hardware.”
I would suggest you use Adafruit Motor Shield V2. Adafruit Motor Shield V2 is an add-on shield that you can plug into Arduino Uno.
You can create a motorshieldv2 object using the add-on shield specified above and connect a stepper motor to the appropriate pins on the motor shield. For stepper motor connection use stepper object.

i read the documentation of shield and stepper.
is it possible to do microstepping by increasing the 'number of steps per revolution ' specified.
motor = stepper(shield,1,4000{steps per revolution},'step type','Microstep')
how to go about the hardware connections for microstepping?

since adafruit shield can control only 2 motors at a time,is there any other way to control 3 motors simultaneously.
for my project i need to control 3 motors.
thanks.
