When using this shield, on the hardware, you need to use it with the control board (MEGA2560 board), the drive board (such as A4988), the motor (42 stepper motor) and others. And you need to burn the firmware to the control board. So need to use the software Arduino IDE, and the special upper computer software, such as Repetier-Host software.
