    Can I connect grblShield to the Raspberry Pi directly? What interface grblShield uses to interract with the Arduino (pins)?

    The pinout schematics can be found here:

    What is the role of Raspberry pi in this method?

    I mean not Raspberry pi. What is the role of AlaMode?

    It is loaded with gbrl. Without it you do not have grbl.. then you do not have any code to drive the grblshield. You can always get an regular arduino and hook it up via usb to the rpi. This works fine too. The way Wyolum did it they used the broken out USART rx and tx pins (bypassing the USB). Saves you a usb port.

    But is it possible to control grblShield with Raspberry Pi without Arduino?
    RaspberryPi have GPIO too.
