1. Arduino Software 1.5.8 Installieren (http://arduino.cc/en/pmwiki.php?n=Main/Software)
  2. RepRap Firmware 0.92 konfigurieren und herunterladen (http://www.repetier.com/firmware/v092/
  3. The Due implementation of the default arduino disables the watchdog feature at
    startup. Due to ARM limitation, it is not possible to enable a watchdog once it
    is disabled. For that reason, the watchdog feature does not work with default
    Arduino installation. To solve the problem copy the modified version as follows:

    boards.txt needs to <ArduinoInstallPath>/hardware/arduino/sam

    It contains the 2 original entries plus a new one called Arduino Due for Repetier.
    If you have modifed the boards.txt before, add only the last entry in boards.txt.

    Copy the folder arduino_due_repetier to

    After a restart you have a new board in your list. Use it only if you
    compile with watchdog feature enabled (which is the preferred way for increased safety)

  4. Arduino Due mit dem Computer verbinden. Programming Port -> Computer
  5. Motoren einstellen mit Vref Pot und Decay Pot (siehe http://forums.reprap.org/read.php?249,451787,453190)

    Wenn enable auf LOW steht fließt kein Strom und die Motoren lassen sich drehen.

    INVERT_X_DIR ändert die Laufrichtung und ist hiert erstmal nicht das Problem.

    Folgendes ist bei Repetier / RAPS128 richtig:

    // For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1
    #define EXT0_ENABLE_ON 1

    // For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1
    #define X_ENABLE_ON 1
    #define Y_ENABLE_ON 1
    #define Z_ENABLE_ON 1

  6. Verbindung zu Repetier Host funktioniert nur über den Programmier Port.
  7. 12Bit A/D Wandler Arduino Due
