    Hey Helpers,

    I need help with my Grbl-shield.
    If I communicate with my arduino with 0.8c Grbl Software without the Grbl-Shield being connected there are no flaws and no errors accure.(I am communicating throught the Arduino Serial Monitor at 9600Baud)
    As soon as i plug in the Grbl-Shield and power it with my already tested 24 Volt Power-Supply the communication shuts down and i get no signal out of it and the returned strings are always “OK” even when i type $$ to view the details.

    I hope you can help me soon.
    Thanks for helping.

    You are powering down everything before plugging the shield into the Arduino?
