Arduino controller for a generic printing machine. It's on a early development status.
It's thought to be used with my Android paint tool: http://www.youtube.com/watch?v=dBtlcxkml6k (project repository: https://github.com/santicastro/AndroidGCodePainter)
Some working samples:

Previous prototype:
The electronics diagrams are not yet available, they will be soon.
The 3D printable parts of the marker painter are available in https://github.com/santicastro/3DModels/tree/master/WallPainter but it's a prototype and not well organized, sorry.
