A closer look
3018 REX CNC Router Machine, Pre-Assembled for Beginner & STEM · Technical features from Genmitsu.
Genmitsu is SainSmart’s CNC range. The 3018 REX is part of its desktop CNC line; compare the current specifications and package contents for your intended work.
10-Minute CNC Router Setup:
Traditional 3018 CNC kits take over 2 hours to assemble by hand. The 3018 REX ships pre-assembled and modular, so beginners finish setup in under 10 minutes and start cutting sooner
Expandable CNC Router System:
Add a laser module or 4th-axis rotary attachment anytime through built-in ports, so you never outgrow this machine. Built-in WiFi sends jobs wirelessly, no cable required
High-Speed CNC Cutting Up to 3000mm/min:
Quiet, independent stepper drivers keep noise down. Speed nearly doubles the 1500 to 2000mm/min of standard CNC routers, so projects finish sooner
Reinforced X-Axis for Precise Cuts:
A 10mm optical shaft and HG15 rail on the X-axis hold cuts to within ±0.1mm. A reinforced Z-axis and 91mm clearance fit thicker stock, and the Y-axis upgrades to a dual-rail kit, sold separately
Enhanced Safety & Easy GRBL Control:
Equipped with physical X/Y/Z limit switches and an instant Emergency Stop button for max safety. Fully compatible with mainstream GRBL 1.1h software, ensuring an easy learning curve
Fifteen Years of Makers, Eight Years of CNC - Not Just Machines
The 3018 REX is designed for desktop CNC projects. Refer to the current manufacturer documentation for setup, compatible accessories and operation.

FAQs
Is the 3018 REX a good CNC router for beginners? Yes - the 3018 REX is purpose-built as an entry-level CNC machine. Pre-assembled construction, physical safety switches, and GRBL software compatibility mean you don't need any prior CNC or programming experience to get your first project cut. How quiet is the 3018 REX compared to other desktop CNC routers? The 3018 REX runs on a 32-bit board with independent silent drivers, making it significantly quieter than standard 8-bit 3018-class machines - quiet enough for apartments, classrooms, and shared workspaces. What materials can the 3018 REX cut and engrave? Like other Genmitsu 3018-series CNC routers, the REX is built for wood, acrylic, PCB, and soft metal (like brass and steel) - ideal for signs, personalized gifts, classroom projects, and small-business products. Can I upgrade the 3018 REX later? Yes. The frame supports a Y-axis linear rail upgrade and native 4-axis mounting, and the mainboard includes a 3-pin laser port - so the REX is designed to grow from your first project into more advanced ones. Is the 3018 REX 15th Anniversary Edition really limited? Yes - only 300 units exist, each with its own serial number badge mounted on the machine. Once the run sells out, this specific edition won't be made again.
