Arduino Firmware for Eggbot / Spherebot with Inkscape-Integration

Version 1.6a tested with Inkscape Portable 0.91, Eggbot Extension and patched eggbot.py

Regards: Eggduino-Firmware by Joachim Cerny, 2015

Thanks for the nice libs ACCELSTEPPER and SERIALCOMMAND, which made this project much easier. Thanks to the Eggbot-Team for such a funny and enjoyable concept! Thanks to my wife and my daughter for their patience. :-)

Features:

  • Implemented Eggbot-Protocol-Version 2.1.0
  • Turn-on homing: switch-on position of pen will be taken as reference point.
  • No collision-detection!!
  • Supported Servos: standard analog mini servos like TG9e, SG90, ES08MA, HXT900, etc.
  • Full Arduino-Compatible. I used an Arduino Uno
  • Button-support (3 buttons)

Tested and fully functional with Inkscape.

Installation:

  • Upload Eggduino.ino with Arduino-IDE or similar tool to your Arudino (i.e. Uno)

  • Disable Autoreset on Arduinoboard (there are several ways to do this... Which one does not matter...)

  • Install Inkscape Tools wit Eggbot extension. Detailed instructions: (You yust need to complete Steps 1 and 2) http://wiki.evilmadscientist.com/Installing_software

  • Eggduino cannot be detected by default by the Eggbot-extension Hopefully, the guys will fix this later on. But we can fix it on our own.
    Go to your Inkscape-Installation folder and navigate to subfolder .\App\Inkscape\share\extensions

For version 2.5.0:

- open file "eggbot.py" in text editor and search for the line:
    "Try any devices which seem to have EBB boards attached"

- comment that block with "#" like this:
    # Try any devices which seem to have EBB boards attached
    # for strComPort in eggbot_scan.findEiBotBoards():
    #   serialPort = self.testSerialPort( strComPort )
    #   if serialPort:
    #       self.svgSerialPort = strComPort
    #       return serialPort

- In my version lines 1355-1360

For version 2.7.1:

- open file "ebb_serial.py" in text editor and search for the following block:

    EBBport = None
    for port in comPortsList:
        if port[1].startswith("EiBotBoard"):
            EBBport = port[0]   #Success; EBB found by name match.
            break   #stop searching-- we are done.
    if EBBport is None:
        for port in comPortsList:
            if port[2].startswith("USB VID:PID=04D8:FD92"):
                EBBport = port[0] #Success; EBB found by VID/PID match.
                break   #stop searching-- we are done.      

- replace "04D8:FD92" with the VID/PID of your Arduino device.  

- alternatively, you can replace "EBBport = None" with your specific port number:
    EBBport = "COMxx"               #Windows
    EBBport = "/dev/tty[something]" #Linux/Mac
