Description
Product Overview
The ACMER Ascarva 3 S is a compact yet powerful CNC router designed for makers, hobbyists, and small workshops that demand precision and flexibility. Powered by a 500W (48V) high‑speed DC spindle capable of reaching 12,000 RPM, the machine provides the torque needed to cut through a variety of materials, from soft woods and acrylics to tougher plastics, MDF, nylon, and even thin metal sheets. Its reinforced aluminum alloy frame and extruded panels give the unit a solid, vibration‑damped platform that maintains dimensional stability during long cutting runs.
With a working envelope of 11.8″ × 7.1″ × 3.1″ (300 × 180 × 78 mm), the Ascarva 3 S offers enough space for intricate signage, decorative panels, prototype parts, and small‑scale production runs. The machine’s weight of 28.3 lb (12.8 kg) strikes a balance between portability and rigidity, allowing it to be moved when needed while staying firmly anchored during operation.
Usage
Designed with a modular DIY ethos, the Ascarva 3 S can be integrated into a variety of work environments. In a home workshop, it fits comfortably on a standard workbench, providing a reliable platform for weekend projects such as custom furniture inlays, personalized gifts, and hobby‑grade CNC engraving. In educational settings, the router serves as a hands‑on teaching tool for engineering, design, and digital fabrication courses, illustrating the principles of computer‑controlled machining.
For small businesses, the router’s USB‑based ESP32 controller enables seamless connection to Windows, macOS, or Linux computers. Popular open‑source software packages like Candle, Universal Gcode Sender (UGS), and Easel are fully supported, allowing users to import DXF, SVG, and G‑code files directly. The machine’s six limit switches and an emergency stop button add layers of safety, making it suitable for environments where multiple operators may be present.

FAQ
What materials can the Ascarva 3 S cut?
The router is capable of cutting wood, MDF, plywood, acrylic, polycarbonate, PVC, nylon, and thin metal sheets up to 1 mm thickness when using appropriate cutting tools and speeds.
Do I need any additional accessories to start using the machine?
All essential components—including the spindle, controller board, limit switches, and power supply—are included. You will need a compatible computer, a USB cable, and cutting tools (end‑mills) which can be purchased separately.
Is the machine compatible with my existing CNC software?
Yes. The Ascarva 3 S works with Candle, Universal Gcode Sender, Easel, and other software that accepts standard G‑code files. It also supports common file formats such as DXF, SVG, and STL (converted to G‑code).
How does the safety system work?
The router features an emergency stop button that immediately cuts power to the spindle, as well as six limit switches that prevent the carriage from moving beyond its intended travel limits, protecting both the machine and the workpiece.
Can I expand the machine for larger projects?
Yes. The modular frame allows you to add extension plates or upgrade to a larger work envelope. Additional accessories, such as a vacuum table or dust extraction system, can also be integrated to enhance functionality.
