G-code for RepRap is a program which reads a sequence of instructions in the G-code format

(typical file extension .nc , .ngc, or .gcode), and uses these instructions to control a three-axis Cartesian

position system as designed for the RepRap project [http://reprap.org].



In this way the RepRap electronics and hardware can be used for subtractive manufacturing techniques,

such as milling, drilling, laser cutting, and plotting. One potential use is to mill printed circuit

boards (PCB s), an alternative to using etching chemicals. The rest is up to your imagination.
