1. DIY Professional Leveling System
This project is a Slab Leveling Mill designed for resurfacing large raw wood slabs (live edge) with high precision. It uses a smart, accessible design that doesn't require complex machining.
Standard Profile Build: Engineered to be built using standard high-resistance aluminum profiles and a solid wood frame.
Carriage Structure: The router is mounted on a sliding carriage that moves smoothly over a fixed rectangular frame.
2. Siemens NX Parametric Design
The true strength of this project lies in its Siemens NX engineering:
Fully Customizable: The entire assembly is parametric. You can easily modify the sliding slots (asole) and the overall dimensions in the CAD file to match the specific aluminum profiles you have or the size of the slabs you need to level.
STEP Files Included: High compatibility with all CAD software (Fusion 360, SolidWorks, etc.) for quick adjustments to the profile sections.
3. Optimized for CMT 7E
The mounting plate and hole patterns are specifically modeled for the CMT 7E router, ensuring a perfect fit and easy access to the tool's controls.

Files Included in the Kit
STEP Files: Universal 3D data for easy viewing and modification.
On request: Parametric Source Files: Native NX files for deep customization of the geometry.
Assembly Guide: Clear references for cutting your standard profiles to length.
Author's Note: This jig is designed for the maker who wants industrial-level results using standard off-the-shelf components. No CNC required—just clean cuts and smart assembly. Since the file is parametric, you can scale it from a small desktop version to a massive slab-leveling station in seconds.
