200W Spindle | 12,000 RPM | 420 x 420 mm | 3-Axis CNC
AtomStack C4 Pro CNC Router: A 200W Desktop Mill With Room to Grow
The C4 Pro is a desktop CNC router built around a rigid all-metal gantry: a 200W high-torque spindle (2.5 N.m, 12,000 RPM) on linear guides across a 420 x 420mm working area. It routes wood, plastic, PCB, soft metals and composites for signage, decorative panels, mold making and precision prototyping.
It is built to be upgraded, not replaced: the spindle can go to a higher-power 500W option, and the tool head swaps between spindle and laser modules for hybrid CNC-plus-laser work. Homing and zeroing routines simplify setup, and it works with LightBurn, LaserGRBL and Candle.

Why the C4 Pro
200W High-Torque Spindle
2.5 N.m of torque at 12,000 RPM for routing wood, plastic and soft metals, upgradeable to a 500W spindle for faster, deeper cuts.
420 x 420 mm Working Area
Room for signage, furniture accents, decorative panels and multi-piece layouts on one bed.
All-Metal Frame, Linear Guides
A rigid gantry structure with linear guides and lead screws that holds the tool path accurate and keeps vibration in check during heavier milling.
3-Axis Control
Smooth, stable movement across X, Y and Z axes for carving, milling and engraving in a single setup.
Hybrid Tool Design
Quick tool changes, including spindle and laser module swaps, so the same machine can route one job and laser-engrave the next.
Safety Built In
Emergency stop, protective housing and chip guards, with accessible components that keep cleaning, lubrication and alignment straightforward.
