G-Code - KEYES ROSTOK Manual And Manual

8. G-code

This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they
work. The main target is additive fabrication using FFF/FDM processes (3D printing). Codes for
print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are
quite usable for CNC milling and similar applications
As many different firmwares exist and their developers tend to implement new features without
discussing strategies or looking what others did before them, a lot of different sub-flavours for the
3D-Printer specific codes developed over the years.
