Universal Gcode Sender (UGS) is a desktop G-code sender for communicating with CNC controllers including GRBL, TinyG, g2core and Smoothieware.
The application is written in Java and packages the components needed for normal operation. UGS goes beyond simply streaming a prepared G-code file: its modular desktop environment provides machine-control, visualisation and design tools that can cover much of the workflow between preparing a job and running it on a CNC machine.
This is free and open source software.
Key Features
- Communicates with GRBL, TinyG, g2core and Smoothieware controllers.
- 3D G-code visualisation displays the toolpath together with live tool-position feedback.
- Provides jogging, machine positioning, coordinate management and common controller commands.
- Includes probing tools for locating workpieces and establishing accurate work coordinates.
- Designer provides vector drawing tools and can generate G-code toolpaths without requiring a separate CAM application for simpler jobs.
- Basic G-code editor allows jobs to be inspected and modified before machining.
- Supports customizable panels, actions and keyboard shortcuts.
- Plugin architecture adds specialist tools without requiring them to be part of the core interface.
- Supports gamepads and joysticks for machine jogging and other controls.
- Includes a web pendant for controlling a machine from another device on the local network.
- Provides configurable G-code processing including removal of comments and whitespace, decimal truncation and arc conversion.
