I've written two little console scripts to upload GCode to Zaggo's SpereBot. See Thing http://www.thingiverse.com/thing:7656One is in http://www.python.org/ the other in http://www.tcl.tk/The python version runs on Linux and Mac. The TCL version is only tested on Linux. They should both run on Windows.The current version can always be found on https://github.com/tgfuellner/SphereBotInstall Python or TCL. I think for Mac the python version is better. For python You also need http://pyserial.sourceforge.net Edit the script and change the Device and Baudrate. Then call it like: ./feeder.py Your-Nice-File.gcode
