This is a fork of the Yura80/EggDuino firmware that adds support for 28BYJ-48 Stepper motors driven by ULN2003's off Arduino pins 2,3,4,5 for the rotational axis, pins 6,7,8,9 for the pen axis and pin 10 for the servo. Tested with Arduino IDE 1.8.0 running http://www.thingiverse.com/thing:1461709

This is the fork of cocktailyogi/EggDuino firmware with added support for servo lowering/raising speed and pin assignment for Protoneer CNC Shield.

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
