    Just a note, I have gotten my steppers to move. However, I am not able to get or send responses from the arduino software serial monitor. If I use a serial port through other software I CAN send and receive from the arduino /w grblsheild.

    I was able to program my Arduino Uno with the grbl.hex using the ARP Arduino Uploader. I had to delete “-b19200” from the “AVR Dude Params” text.

    I can only hope this helps someone else. Good luck, and thank you for all of your help!

    Thanks for the help Alden, and thanks for the offer Riley.

    I have found my first problem an AVRDude error. It was not in sync while I was trying to upload.

    I am using an Arduino Uno with the atmega328, Windows 7, ARP Uploader, GrblSheild

    I did get grbl to upload on the Uno by making a change in the “AVR Dude Params” text within ARP Uploader. If you Erase the “-b19200” it will allow it to upload on the Uno.

    Using a serial monitor from the arduino software I get:

    Grbl 0.7d
    ‘$’ to dump current settings

    or

    Grbl 0.6b
    ‘$’ to dump current settings

    I’ve tried both…. This opening message is the only response message I can get from the arduino. When I try sending the $ command, I get no response. I have tried sending this with and without the grblesheild atatched.

    Riley,
    If you are able to get grbl to work on these chips for use with Uno, what method are you using?

    Also, if I can see the start up response from the grbl software, why can’t I interact with it?

    Any thoughts?
