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)
