This is an adaptation of Marlin firmware, for the use in Clay 3D Printing.
The firmware enables the interaction between a Ramps 1.4 Arduino Mega Shield board, and BioFeeder.
The comunication uses through Experimental I2C.
BioFeeder is an Arduino Uno Shield that controls paste extrusion system, I have been using it for BioComposites, but if can be used for sodering paste, clay, etc.
The extruder is an auger screw based system wich control comes directly from the Marlin firmware, wich follows the Gcodes instructions from the slicer.
