g-code++ - an extension of g-code (might rename later)

A lightweight G-code interpreter written in C++ inspired by the NIST rs274ngc interpreter.

The output of the interpreter may be used to drive 3-axis machines.

Build and Install

Required tools:

• Any compiler for C++17 or later
• make

Build

make antlr
make dev
./build/gcode++ <filename>

Install

By default, make install builds and installs the binary into /usr/local/bin.

make install # optional: `DIR=/usr/bin` or something
gcode++ <filename>

Test

make test unit       # runs all unit tests
make test regression # regression tests

Supported codes:

• Motion: G0, G1, G2, G3, G4
• Plane Select: G17, G18, G19
• Units: G20 (inches), G21 (millimeters)
• Positioning Modes: G90 (absolute), G91 (relative)
• Coordinate Systems: G10, G43, G54-G59, G92

ANTLR4 Dependency

If you want to make changes to the antlr grammar, Java is required since make antlr depends on Java. You'll have to run make antlr to test as well as build the binary.
