The creators of LightBurn — the widely acclaimed software for laser cutters — are expanding into subtractive manufacturing with MillMage, an integrated CAD/CAM/Control platform built specifically for CNC routing. Now available as a public “release candidate,” MillMage offers a powerful, precision-focused alternative to current CNC software, aimed at skilled users navigating the complex world of material removal.
Unlike LightBurn, which was purpose-built for laser workflows, MillMage addresses the unique challenges of CNC routing, including tool pressure, Z-axis control, and workholding, while preserving the intuitive interface and 2D design capabilities LightBurn users love.
Designed for Experienced CNC Users
MillMage sets itself apart with a rare offering: a fully integrated toolchain that spans CAD (design), CAM (toolpath generation), and machine control in one cohesive application. That integration removes the need to juggle multiple tools, streamlining workflow for those experienced enough to take full advantage of its capabilities.
“This is not an entry-level app,” the developers emphasize. “It’s designed for people who already know what they’re doing and want a powerful tool to match.”
From Lasers to Routers: A Philosophical Shift
Although MillMage inherits design sensibilities from LightBurn, its shift to CNC routers means a departure from the simplicity of laser work. Unlike laser cutters, which operate in fixed bed sizes and with minimal physical resistance, routers must physically cut through materials, introducing new concerns such as kickback, spindle forces, and multi-axis motion.
To meet these demands, MillMage introduces:
- Z-probing support for accurate tool height calibration
- Project Setup Wizard for defining material dimensions, origin points, and Z-zero levels
- Dynamic workspaces based on project-specific stock sizes (unlike LightBurn’s fixed bed concept)
These features provide the groundwork for reliable, precise, and safe operation in environments where error can result in broken bits, damaged machines, or ruined stock.
New Operation Assignment Model
One of the most noticeable changes for LightBurn users will be the operations workflow. In MillMage, design layers are separated from operation logic, meaning users must explicitly assign toolpaths and machining operations in a dedicated operations panel. This promotes deliberate control and reduces ambiguity in complex setups.
However, for those who prefer LightBurn’s color-coded, layer-based system, an “Auto-Use Layer” option allows MillMage to emulate that familiar behavior.
Direct Machine Control – with Limits
MillMage includes machine control features, but only for officially supported firmware types. Users of unsupported systems can still export G-code for use with external controllers. This limited direct control is a deliberate decision to ensure reliability and safety, rather than pursuing universal compatibility at the expense of quality.
Safety First: Not for Beginners
The MillMage team is clear: this tool is for experienced CNC users only. CNC routers carry real risks, from flying debris to motor crashes, if used improperly. Unlike LightBurn, which found a large following among hobbyists, MillMage requires users to understand feed rates, spindle speeds, and workholding principles before jumping in.
The software’s documentation is still evolving, and while tutorials and walkthroughs are in development, users are strongly encouraged to consult their machine manufacturers and use caution when testing operations.
Community-Driven Development
While MillMage is nearing completion, the release candidate phase is a collaborative effort. Developers are actively gathering feedback from early users through forums and support channels. Planned updates include:
- Improved setup documentation
- Interactive tutorials
- Feature walkthroughs for toolpath generation and safety setup
The MillMage team hopes this iterative feedback loop will refine the platform into a trusted industry tool — just as LightBurn became the gold standard for laser software.
Poised to Reshape CNC Routing Software
MillMage doesn’t attempt to simplify CNC routing for casual use. Instead, it leans into complexity with clarity and precision, giving engineers and CNC veterans the tools they need to control every aspect of the machining process from start to finish.
Whether MillMage achieves the same market adoption as LightBurn remains to be seen, but early signs suggest it’s well-positioned to become a favorite among advanced users looking for a serious, integrated CNC routing solution.
The public trial version of MillMage is available now, and users can submit feedback through the official support channels. A full release is expected once final revisions and documentation are complete.
