So I need some Easter attraction for them :)
The SphereBot can plot images on spherical objects like table tennis balls, golf balls, eggs etc.
It is inspired by the original EggBot by EvilMadScientist, but built from 2 old stepper motors and some steel rods (all cannibalized from old flatbed scanners), some MDF and plywood and a few 3d printed parts (printed with my MakerBot Cupcake).
The electronics are simply an Arduino and two Polulu A4983 stepper motor drivers (on the bread board).
The custom Arduino firmware directly interprets GCode sent over the serial port. So itâ€™s no problem to print GCode from MakerBot Unicorn designs directly on the SphereBot.
Thanks to the excellent Inkscape plugin from Marty McGuire (http://www.thingiverse.com/thing:5986), itâ€™s easily possible to convert all kinds of vector drawings (eps, svg, etc) to printable GCode.
The firmware is open source and can be found here:
A video of the SphereBot in action is available on YouTube:
Meanwhile I drew plans for the wooden parts (left & right side and the X-axis stepper motor retainer plate). See
I just uploaded STL and SCad files for the printed parts.
The SphereBotSender GUI is now also available in a Processing implementation, i.e. it runs on Mac OS X, Windows and Linux.
See 'SphereBotSenderBinaries.zip' below.

I have Spherebot printed and made ??with my Prusa Mendel
Now I have a question, I use Spherebot ui.exe, everything works perfectly manually
but now I would like to have a calibrate test file in Gcode
Who give a calibrating Gcode file that I can use to work as it should (something like a circle or square or text .....??)
Full step and quarter step as it can be
Micro Step Resolution = Full step or and quarter step
Egg = 6cm long and 42mm diameter
The final stop should be to the left or right are ( i think left ???)
The sources for the Arduino firmware and the Mac OS X (Snow Leopard) application are available on GitHub. You find the links to the repositories here:
