    Hi, new user here.

    It seems like g2core is not booting on my Due.

    I’ve uploaded g2core v101.03 to my Arduino Due following the instructions here. It would appear that flashing g2core to the Due was successful if I understand it correctly; within the cmd window it says:

    Erase flash
    Write 185452 bytes to flash…
    Verify 185452 bytes of flash…
    Verify successful
    Set boot flash true
    CPU reset.

    Then I unplugged my Due stacked my gShield v5b on-top of the Due with the 24v power supply hooked up (not powered). I then plug in the Due to the computer, power up the power supply and I get a pretty blue light on the gShield. However, when I open up “Universal Gcode Sender – Platform”, select firmware:g2core, COM and Baud: 115200 I get no response upon connecting.

    Any ideas why g2core seems to be in a coma?

    P.S. even trying to listen on the Arduino IDE Serial Monitor shows no activity, not even gibberish.

    … Couldn’t find a way to edit…

    SOLVED!

    For anyone dealing with a similar issue. With my Due R3 board, the .bin file had to be flashed using the “Programming USB” and then switched to the “Native USB” port for use.

    Wish they’d write more documentation for newbies like me.

    Based on you description, I am a little surprised that your initial flashing of the Due appeared to work. The command
    mode COMx BAUD=1200
    in step 3 is unique to the Programming port, it erases flash on the Due.
    Hint – don’t leave you COMx port at 1200 baud, or you will erase flash next time you connect.
    I’ll suggest an update to the programming procedure

    Thanks for the guidance cmcgrath5035!

    That would explain a few things, it sounds like by leaving it at 1200 I was wiping it every time, but this last time since I switched to the Native port immediately it isn’t flashing?

    Quite a learning curve, I’m daydreaming of the day I’m proficient enough to write an “idiots guide” haha!

    Learning curve indeed, this is complex stuff. While the DUE plus Gshield is still supported, most of the heavy work is aimed at a soon to be released integrated controller (gquintec) which is a 5 motor board plus 3D Printer control add-ons.

    To get a feel for what is active, watch activity at https://github.com/synthetos/g2/issues
