MatterControl 1.5.3 for OS X cannot connect to FormBot via USB



  • I am using MatterControl 1.5.3 on OS X 10.9.5, and I am using FormBot, which is similar to gCreate gMax.

    I have selected the 3D printer using the wizard, and plugged the printer to the computer via USB. However when I click "connect", it says "Unable to communicate with printer" "Status: Unknown Reason"

    Then I clicked "edit" to open the edit dialog. For serial port, it lists:

    /dev/tty.Bluetooth-Incoming-Port

    /dev/tty.Bluetooth-Modem

    /dev/tty.usbserial-A600DQCG

    and the third one is chosen


    Then the baud rate are shown:

    115200

    250000

    other


    and it is the 250000 that is selected.

    and the "Auto Connect" option is checked.


    When I switch to 115200, the printer takes forever to respond (never).


    So anything wrong here? And what setting should I use?


    Thanks!




  • With everything you've mentioned, it seems like the printer should be able to connect.

    Can you confirm that the printer can connect using similar software (Cura, Arduino IDE, etc.)?



  • Oh..... after I installed an updated version of FTDI driver, it works 🙂

    Could you please tell us the correct /dev file and baud rate? Is it /dev/tty.usbserial-<name> and 256000?

    Thanks!



  • Glad to hear it!

    250000 is the standard baud rate; /dev/tty.usbserial-<name> sounds right.
