A Simple Slicer

Brian Tuan

Ideally should slice STL meshes into G-Code toolpaths.

Tested on a few geometric primitives (sphere, cube, etc.). GCode read at images/HollowCylinder.png.

Slicing Philosophy

Models are sliced from bottom to top, with supports and infill being the same hexagonal honeycomb pattern as specified by infill parameters. Default params are located at the top of the src/slicer.py file and may be modified to de- sire. Further specification of infill vs supports may be added in the future.

Usage

Help menu:

$ ./src/main.py --help
Usage: main.py [OPTIONS]

Options:
  --stl TEXT       Path to input STL file.
  --preamble TEXT  Path to GCode preamble.
  --cleanup TEXT   Path to GCode cleanup.
  --outpath TEXT   Path to output location of GCode.
  -v, --verbose    Toggle to True for verbosity.
  --help           Show this message and exit.

Example run:

$ ./src/main.py --stl models/10uCubeRef.stl --preamble config/preamble.gcode --cleanup config/cleanup.gcode --outpath out.gcode

Automated testing:

$ ./make_models.sh
