Arduino Firmware for Eggbot / Spherebot with Inkscape-Integration

Regards: Eggduino-Firmware by Joachim Cerny, 2014

Thanks for the nice libs ACCELSTEPPER and SERIALCOMMAND, which made this project much easier. Thanks to the Eggbot-Team for such a funny and enjoable 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 ine type ;-) I use Arduino Servo-Lib with TG9e- standard servo.
Full Arduino-Compatible. I used an Arduino Uno

Tested and fully functional with Inkscape.

Installation:

Upload Eggduino.ino with Arduino-IDE or similar tool to your Arudino (i.e. Uno)
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: Instructions: Go to your Inkscape-Installationfolder and navigate to subfolder: .\App\Inkscape\share\extensions open File "eggbot.py" in texteditor and search for: "Try any devices which seem to have EBB boards attached" delete or uncomment the following 6 lines (example: in Version 2.3.4 line 1353-1357) save file and enjoy your selfmade Eggbot/Spherebot with full Inkscape-Integration.
Prepare some Eggs and have fun.

Todos and Feature-Wishlist:

collision control via penMin/penMax
implement homing sequence via microswitch or optical device
implement hardware-button , EGGBOT-Guys call it "PRG-Button"
Replace Stepper Control ACCELSTEPPER --> DDS, interruptbased control to improve step-precision and smoothness. (I really need help with this, but this would be the best improovement)
