I've implemented a backend system to send G-code commands directly to a GRBL-based pen plotter via a serial connection.
Key changes include:
- Added `grbl_communicator.py` with a `GRBLCommunicator` class to handle serial connection, G-code command sending, and GRBL response parsing ('ok', 'error').
- Updated the `/api/send_job` route in `app.py` to utilize `GRBLCommunicator` for processing and sending G-code jobs. Includes default serial port and baud rate configuration.
- Added `pyserial` to `requirements.txt` for serial communication.
- Implemented comprehensive unit tests for `GRBLCommunicator` in `test_grbl_communicator.py`, using `unittest.mock` to simulate serial port interactions.
- Updated `README.md` with details on the new backend, configuration instructions for serial port/baud rate, and dependency information.
The system now allows you to send G-code from the frontend, which is then relayed to the connected GRBL device. Error handling for connection issues and GRBL errors is included.
