Forked from https://github.com/cocktailyogi/EggDuino.

The aim of this fork is to cleanup the codebase to allow hacker to easily add their tweaks.

• config.h: the pin configuration for your board.
• EBBParser: parser interface for the EBB protocol.
• EBBHardware: implement the necessary methods to interpret the events and drive the 2 steppers + servo

To compile it, either use platformio or the Arduino IDE. For the Arduino IDE, the VarSpeedServo librarie need to be installed first.

Eggduino

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: At least one type ;-) I use Arduino Servo-Lib with TG9e- standard servo.
• 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

• Because of an bug in the Eggbot-extension (Function findEiBotBoards()), the Eggduino cannot be detected by default. Hopefully, the guys will fix this later on. But we can fix it on our own. It is quiete easy:

    - Go to your Inkscape-Installationfolder and navigate to subfolder .\App\Inkscape\share\extensions
    - open File "eggbot.py" in texteditor and search for 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
