This is a 3D printing STL-to-GCode slicer, written in Python, based on the Clipper geometry library. It will let you take STL files and generate a GCode path file that you can send to your RepRap 3D printer to print the object.
Install using PyPi (NOT IMPLEMENTED YET):
unzip mandoline-py.zip cd mandoline-py pip3 install .
Installing from sources:
python3 setup.py build install
To just validate a model, checking it for manifold errors, just run
mandoline with the name of the file:
mandoline testcube.stl
Any error messages will be printed to STDERR, and the return code
will be non-zero if errors were found.
To slice a file into GCode, you need to specify the file to write to with the -o OUTFILE arguments:
mandoline -o testcube.gcode testcube.stl
If you want to force it to skip validation, then add the -n argument:
mandoline -o testcube.gcode -n testcube.stl
To display all slicing config options, use the --show-configs argument:
mandoline --show-configs
To get descriptions about all slicing config options, use the --help-configs argument:
mandoline --help-configs
You can set slicing options on the command-line with -S NAME=VALUE args:
mandoline -S layer_height=0.3 -S skirt_loops=3
You can write changed options to the persistent slicing configs file using the -w argument:
mandoline -S layer_height=0.3 -S brim_loops=3 -w
You can query the value of a slicing config option with the -q OPTNAME argument:
mandoline -q layer_height -q brim_loops
You can view the sliced output in a GUI window if you add the -g argument. In this window, up and down arrow keys will move through the slice layers, and the 'q' key will quit and close the window. The keys 1 - 4 or - and = will zoom the image.
