## Basement Ooza Basics
|
|
|
|
The hacked together pipeline is as follows given an svg `$SVG`. You may use the `Woodbine.svg` file as an example for testing.
|
|
|
|
1. Ensure that your SVG has a size set that fits in Ooza
|
|
1. One way to ensure is by setting width & height on the root `<svg>` element
|
|
1. Convert the SVG to gcode via `cargo run --release -- $SVG -o $OUTFILE`
|
|
1. Rewrite the gcode to be compatible with Ooza via `python rewritegcode.py $OUTFILE $FINALFILE`. This will do a few things:
|
|
1. Exit with an error message if the print would go outside the bounds of Ooza
|
|
1. Rewrite the coordinates to center where the print happens
|
|
1. Prepend the header in `ooza/config.g` to the rewritten gcode
|
|
1. Upload `$FINALFILE` to Jobs in Duet and run it

- Use a 3D printer for plotting: (thanks [@jeevank](https://github.com/jeevank) for sharing this) https://medium.com/@urish/how-to-turn-your-3d-printer-into-a-plotter-in-one-hour-d6fe14559f1a

|
- Convert a PDF to GCode: follow [this guide using Inkscape to convert a PDF to an SVG](https://en.wikipedia.org/wiki/Wikipedia:Graphics_Lab/Resources/PDF_conversion_to_SVG#Conversion_with_Inkscape), then use it with svg2gcode
|
|
|
|
- Are shapes, fill patterns supported? No, objects must be converted to paths in Inkscape with `Object to Path` for use with this program. See [#15](https://github.com/sameer/svg2gcode/issues/15) for more discussion.
