    No, I don’t. I can’t guarantee that UniversalGcodeSender works with GRBL.

    Hi Dan
    Thank you for your reply

    My last problem was solved.

    if I want to use a LASER for cut in “2-axis Arduino CNC Gcode Interpreter”, How do I connect LASER driver to “L293D Motor Driver Expansion Shield for Arduino” to turn off and turn on LASER when cutting?

    There is no obvious way to connect a laser driver to the L293d motor shield. Also…that sounds really dangerous. I do not recommend this.
