    Sorry for my poor English. When i connect the Inkscape to EBB board, and open the extensions to start servo calibration, i receive the following message, and the servo d´not move.

    Traceback (most recent call last):
      File “”, line 1406, in <module>
      File “C:Program”, line 268, in affect
      File “”, line 281, in effect
      File “”, line 1299, in EggbotOpenSerial
        self.serialPort = self.getSerialPort()
      File “”, line 1357, in getSerialPort
        serialPort = self.testSerialPort( strComPort )
      File “”, line 1326, in testSerialPort
        serialPort = serial.Serial( strComPort, timeout=1 ) # 1 second timeout!
      File “C:Program”, line 30, in __init__
        SerialBase.__init__(self, *args, **kwargs)
      File “C:Program”, line 260, in __init__
      File “C:Program”, line 56, in open
        raise SerialException(“could not open port %s: %s” % (self.portstr, ctypes.WinError()))
    UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe3 in position 21: ordinal not in range(128)

    Thanks in advance.

    This error is not actually related to the servo motor in any way. The actual problem is that there is a “bad” character in the file. It is a type of error that we have heard of before, but not been able to reproduce. If you can follow up on our earlier reply to you and send us a copy of the file, then hopefully we can solve this once and for all. If not, you might try using one of our example files while doing your calibrations.


    Can you tell me an email to send a copy of the extensions file of my computer.

    Please reply to the e-mail that we sent you earlier. You can add it as an attachment to your e-mail.
