## What it is
Universal G-Code Sender is a free, cross-platform Java application for sending G-Code to CNC controllers such as GRBL, FluidNC, TinyG, g2core, and Smoothieware. It includes a modular GUI with a 3D G-Code visualizer, editor, designer, real-time overrides, and gamepad support.

## Use cases
- send g-code files to my GRBL CNC controller
- visualize g-code toolpaths in 3D before running a job
- edit and optimize g-code with syntax highlighting
- jog my CNC machine and control real-time overrides
- import SVG or DXF designs and generate toolpaths
- control a laser engraver from my computer
- run a web pendant to control the CNC from a tablet

## When to choose
- you need a free, full-featured desktop sender for GRBL, TinyG, g2core, Smoothieware, or FluidNC
- you want cross-platform support including Windows, macOS, Linux, and Raspberry Pi
- you want built-in visualization, editing, and g-code optimization in one tool

## When to avoid
- you need a lightweight command-line-only sender
- your controller is not one of the supported firmwares
- you require commercial licensing (it is GPL-3.0)
