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 with Eggbot extension.

1. Download and install the latest version of Inkscape (Version 0.91 or newer)
2. Download and install EggBot_250A.exe from: https://github.com/evil-mad/EggBot/releases/tag/v2.5.0
3. Download my patched ebb_serial.py from:

https://github.com/plex3r/plotink/tree/master/libraries

4. Replace the existing ebb_serial.py in your inkscape extensions folder with the patched version.

Ensure there are no other usb / com devices plugged in apart from your Eggbot.

Start inskscape and it should now be able to connect to your eggbot.
