pygrbl-streamer
Stream G-code to GRBL controllers over serial, with progress callbacks, pause/resume/stop and configurable connections. Files and generators are consumed lazily, keeping memory use low.
Used daily for a year in a professional workshop, operating multiple machines in production.
Requires Python 3.10+. Part of the pygrbl family alongside
pygrbl-build.
Install
pip install pygrbl-streamer
Use
from pygrbl_streamer import GrblStreamer
with GrblStreamer("/dev/ttyUSB0") as laser: # "COM3" on Windows
laser.progress_callback = lambda percent, command: print(f"{percent}%")
if not laser.send_file("job.gcode"):
raise RuntimeError("Job did not complete")
This executes the file on the machine. Default connection: 115200 baud, soft reset and automatic unlock. Existing 0.2.0 calls remain supported; new connection options are optional.
Documentation
- Connections: serial settings, retries and controller compatibility.
- Streaming: sending files and generators, progress, pause, resume and stop.
