|
|
|
|
## Run the example
|
|
|
|
Chrome or Edge. Serve over localhost (Web Serial does not work from `file://`).
|
|
|
|
```bash
|
|
cd p5-wallplotter
|
|
python -m http.server 8080
|
|
```
|
|
|
|
Open http://localhost:8080/examples/zickzack/
|
|
|
|
Press **C** to connect, **H** to set home, then **Test** (preview) or **Plot** (send G-code).
|
|
|
|
