README
# saxi
##### make plot good
saxi is a tool for interacting with the [AxiDraw
drawing machine](https://axidraw.com/) by Evil Mad Scientist. It comes with an
easy-to-use interface, and is exactingly precise.
- automatically scales & centers your drawing to fit on the paper
- minimizes pen-up travel time by reordering & reversing paths
- uses a custom motion planning algorithm (inspired by [axi](https://github.com/fogleman/axi)) that's smooth & fast
- automatically splits apart layers based on SVG stroke colors or group IDs
- has a web-based UI, so there's no need to muck around with installing X11 and Inkscape
- can run on a Raspberry Pi or similar, so you don't need to be tethered to your plotter while it plots
### Usage
```
$ npm i -g saxi
$ saxi
Server listening on http://0.0.0.0:9080
Connecting to EBB on /dev/tty.usbmodem1461
```
If you encounter an `EACCES` error when installing the package globally, see [Resolving EACCES permissions errors when installing packages globally](https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally).
#### Raspberry Pi
To install saxi on a Raspberry Pi, first install node.js if you haven't already:
```
$ curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
$ sudo apt-get install -y nodejs
```
and then proceed as above :) If you connect to the raspberry pi over ssh, you might want to run the `saxi` server inside a tmux or screen session to have it stay running even if your ssh session disconnects.
If you want `saxi` to run at boot on the Pi you can use a systemd unit file and enable the service:
```bash
sudo tee /lib/systemd/system/saxi.service <
