Top Recommended Replacements
Fusion (Personal)
FREEBest Direct Ecosystem Alternative
Why we like it
Built on the same HSM kernels as PowerMill; free for non-commercial use; includes 3-axis and 3+2 multi-axis machining; seamless CAD/CAM integration.
Keep in mind
The free version restricts rapid feed rates and simultaneous 5-axis movement; cloud-dependency for data storage.
FreeCAD (CAM Workbench)
Best Truly Open-Source Tool
Why we like it
100% free with no commercial restrictions; supports 2.5D and basic 3D toolpaths; extensive open-source post-processor library for LinuxCNC and GRBL.
Keep in mind
The user interface is utilitarian; lacks the high-end 5-axis collision avoidance and toolpath smoothing found in PowerMill.
Blender CAM
Best for Artistic Machining
Why we like it
Unique ability to generate toolpaths directly from high-poly mesh data; 100% free; supports 4th and 5th axis work; excellent for relief carving and organic shapes.
Keep in mind
Non-traditional workflow geared toward artists rather than mechanical engineers; requires a steep learning curve for Blender's interface.
HeeksCNC
Best for Lightweight Milling
Why we like it
Minimalist and fast; perfect for simple mechanical parts and 2.5D operations; includes a simple integrated CAD environment.
Keep in mind
Limited support for complex 3D surface strategies; development is less active compared to FreeCAD.
PyCAM
Best for STL Roughing
Why we like it
Specifically designed for generating toolpaths from STL files; great for roughing and finishing passes on 3-axis machines; totally free.
Keep in mind
Processing can be slow for large files; lacks modern HSM (High-Speed Machining) toolpath strategies.
DeskProto (Free Edition)
FREEBest for Rapid Prototyping
Why we like it
Incredibly intuitive for beginners; the free edition supports STL and DXF files for full 3-axis milling; professional-grade reliability.
Keep in mind
The free version is limited to 3-axis; multi-axis rotary and simultaneous 5-axis require a paid license.
Camotics
Best for Verification
Why we like it
Essential companion to free CAM tools; provides high-fidelity 3D simulation and collision checking for G-code; prevents machine crashes for $0.
Keep in mind
Does not generate toolpaths; only simulates code generated by other software.
RhinoCAM (Free Demo)
FREEBest for Designers
Why we like it
Lives directly inside Rhinoceros 3D; exceptional for complex surface work; the 'FreeMILL' module provides basic 3-axis toolpaths for free.
Keep in mind
The full suite is a paid subscription; FreeMILL is very limited in its optimization strategies.
SprutCAM (Free Trial)
Best for Robotics
Why we like it
Industry leader for offline robot programming (OLP); handles mill-turn and 5-axis simultaneous work at a lower cost than PowerMill.
Keep in mind
Not free (standard license required); requires dedicated training to master its unique 'machine-aware' workflow.
DXF2GCODE
Best for 2D Production
Why we like it
Extremely lightweight; converts 2D drawings to G-code for milling or laser cutting; supports tool compensation and layer-based depth.
Keep in mind
Zero 3D capability; purely for 2D profiles and pockets.
jscut
Best for CNC Routers
Why we like it
No-install web-based CAM; converts SVG files to G-code instantly; perfect for flat-sheet parts and maker projects.
Keep in mind
Limited to 2.5D work; lacks the precision and control needed for high-speed metal milling.
OpenSCAD (with CAM plugins)
Best for Programmatic CAM
Why we like it
Ideal for parametric jigs and fixtures; can be paired with FreeCAD or external G-code generators for high-precision manufacturing.
Keep in mind
Lacks native toolpath generation; requires a 'code-first' mindset.
