From the 36" Maker to the 14-foot Industrial — every RigidCore ships with AI motion control, a patented composite beam, and full RigidSense sensor integration.
Every tier gets the same 1ms CAN bus loop, the same AI brain. The Maker is not a lesser machine — it is a smaller machine.
8" (203mm) standard. Upgradeable to 12" (305mm) independently of gantry clearance.
8" (203mm) standard. Upgradeable to 12" (305mm) independently of Z travel.

Air-cooled spindles require ~12,000+ RPM minimum. Steel cutting requires water-cooled (3,000–8,000 RPM) plus mist coolant on the workpiece.

A patent-pending adaptive hybrid structural member. Outperforms cast iron at a fraction of the weight. Every RigidCore CNC is built on this technology.
3D-printed gyroid channels create continuous load paths with optimal stiffness-to-weight. Epoxy-filled channels bond skin to core at every contact point.
Fiberglass reinforced polymer tubes at load-critical locations. Galvanically safe, excellent damping, zero corrosion risk in coolant environments.
Epoxy with glass microspheres. 30–40% lower density than pure epoxy with improved vibration damping through impedance mismatch at material boundaries.
Same process produces fast gantry beams (light, high frequency) and damped table beams (dense, vibration absorbing). Same shell, different performance.
Counterbored holes create epoxy mushroom-head keys — geometric interlock that doesn't rely on adhesion. Truss pattern between rails increases bonding surface.
Modular sections under 150 lbs (68 kg) for standard freight. Steel sleeves span joints, transferring full bending loads continuously.
6061 Al extrusion — 1" (25mm) grid. Versatile fixturing with clamps, vises, and stops.
3/4" (19mm) phenolic — replaceable. Ideal for wood, MDF, foam. Sacrificial surface.
MDF plenum + surface gasket + vacuum pump. Full-sheet access with no clamps.
Al T-slot perimeter + vacuum center zone. Clamp the edges, vacuum the field.

Air-cooled is simpler and better for most shops. The moment you want to cut steel, you need water-cooled + mist. Here's exactly which spindle to choose and why.
Air-cooled spindle, no mist coolant needed. Start with 2.2kW ER20 air-cooled. Upgrade to 3.5kW for hardwood production or ATC for multi-tool sign work. Every 48" machine ships ready for this category.
Air-cooled works for light passes. Sustained aluminum production needs 3.5kW with mist coolant. Water-cooled recommended for brass, copper, and production aluminum. Thermal stability matters.
Air-cooled fans die below 12,000 RPM. Steel needs 3,000–8,000 RPM. Water-cooled spindle + mist coolant on the workpiece is non-negotiable. The RigidCore composite beam is specifically designed to damp the chatter that makes steel finishing impossible on aluminum-frame competitors.
Every competitor in our price range builds their gantry from structural aluminum extrusion — damping ratio of 0.001–0.003. Vibration energy introduced at the tool tip bounces around with nowhere to go, producing chatter marks on the cut surface. On wood and foam, this doesn't matter. On steel, it's fatal. The RigidCore composite beam — with its gyroid architecture, GRP tubes, and syntactic foam fill — achieves damping ratios 10× higher than aluminum. Combined with true BLDC servo control from RigidDrive motors and 1ms closed-loop correction from RigidPulse, the result is surface finishes that aluminum-frame machines physically cannot achieve.
