    Hi i am a new user to the forum ,

    i am using Arduino Mega with RAMPS & RepRapdiscount Full Graphic smart controller. I was able to upload the firmware onto Arduino Mega & my LCD also seems to be working.
    Its now showing X,Y,Z axis (After initial Screen).

    i opened Makelangelo software (V 7.23.0) and Select Makelangelo(Custom) in dropdown of settings
    When i try clicking on “Connect” i get a window asking for port to be used.
    When the correct port is selected & OK is pressed Application abruptly closes creating error file.

    Link to the file is given below


    Can anyone confirm if they are also facing similar issues ?

    Anything to be done from my side to get this resolved ?


    Java frames: (J=compiled Java code, j=interpreted, Vv=VM code)
    j jssc.SerialNativeInterface.openPort(Ljava/lang/String;Z)J+0
    j jssc.SerialPort.openPort()Z+65
    j com.marginallyclever.communications.serial.SerialConnection.openConnection(Ljava/lang/String;)V+28

    The error is coming from inside the JSSC native libraries. I can’t directly see the code in those libraries so I’m not much help. Can you open a connection to the robot with Arduino?


    Yes… i am able to upload firmware & move motors & Servo using RepRap LCD encoder..


    Got this working with 7.20 version…
