bCNC is a cross-platform Python application for CNC machines that use grblHAL and GRBL-compatible firmware.
It combines machine control with editing and preparation tools in one program, offering a practical environment for sending jobs, adjusting g-code, configuring workspaces, and handling common CNC workflows from a single interface.
This is free and open source software.
Key Features
- Supports both 3-axis and 6-axis GUI modes.
- Imports and exports g-code, DXF, and SVG files.
- Offers 3D mesh slicing for STL and PLY files.
- Provides probing tools including center finding, Z-probing, autolevelling, height-map display, and tool length probing.
- Includes basic CAM functions such as profiling, pocketing, drilling, thread milling, cutout tabs, and drag knife operations.
- Features a graphical g-code editor with display, movement, rotation, mirroring, and rapid motion optimisation tools.
- Includes user-configurable databases for materials, stock, and end mills.
- Provides g-code plugins including generators for bowls, finger-joint boxes, spur gears, spirographs, and surface flattening.
- Offers a web pendant that can be used from smartphones.
