Control four stepper motors with cnc shield

Hi, I already made a cnc, and I want to made a loom machine. I am wondering if I can use de CNC Shield to move four stepper motors.

I am planning to use gcode with grblgru program, but I also find that I can use the aurduino grbl library, but I have no idea how to programming that.

Am i wrong ?

Do you have some ideas?

You need to post a link to the datasheet for your CNC shield.

Can it accommodate 4 stepper motor drivers?
