Firmware

As the firmware used Eggduino. It's arduino firmware for EggBot / Spherebot with Inkscape-Integration (Github).

For Installation:

Download and unzip Firmware.zip.
For UNO board with CH340G download and install driver: http://www.wch.cn/download/CH341SER_ZIP.html.
Download the ARDUINO IDE here: https://www.arduino.cc/en/Main/Software and install it.
Run the software. Select the Arduino UNO board and the proper COM PORT (should be COM5 or so) in the menu "Tools->Board"…
Open Eggduino.ino from Firmware.zip and upload the Eggduino code to your Arudino Uno.

Controlling program

As the controlling program used Inkscape software.

Download and unzip the Inkscape software Software_inkscape+extension.zip.
EggBot Control Extension already included in the Inkscape from Software_inkscape+extension.zip.
Run the software.

The EggBot Control extension for Inkscape is the tool that you will use to help you test and align the EggBot, as well as transfer your drawings to an egg. Once Inkscape is running, you’ll have an Extensions menu, and on that menu will be a submenu labeled Eggbot.

If the Inkscape does not connect to the device, please check name of your Arduino in to device manager. And change it in ebb_serial.py on line 52 instead of "USB-SERIAL CH340":

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

Use template EggBot (File->New from Template) for your drawing.
