Upgrade your CNC workflow with the Automatic CNC Tool Sensor Mach3 Z‑Axis Probe – a precision‑engineered touch plate that delivers instant tool‑length measurement, auto‑zeroing, and reliable Z‑axis positioning for CNC milling machines, engraving routers, and CNC routers. Designed for seamless integration with Mach3, Mach4, LinuxCNC, and popular controller boards, this probe eliminates manual probing, reduces setup time, and boosts part accuracy.
Key Highlights
- 🔧 Fully Automatic Z‑Axis Probing – Instantly detects tool length and sets the machine’s zero point with a single command.
- 🛠️ Mach3/Mach4 Compatible – Pre‑configured scripts and G‑code support for plug‑and‑play operation.
- 📏 High‑Precision Touch Plate – Hardened stainless‑steel surface with 0.02 mm repeatability.
- ⚡ Rapid Auto‑Zero Check – Reduces setup time by up to 80 % compared to manual probing.
- 🔌 Universal Connectivity – 5‑pin DIN connector works with most CNC control boards and breakout modules.
- 🌐 Compact & Durable Design – Weather‑proof housing protects the sensor in workshop or industrial environments.
Why Choose This Probe?
Whether you’re producing intricate engravings, high‑tolerance milled parts, or custom CNC projects, accurate Z‑axis positioning is critical. Our sensor provides:
- Consistent repeatability for batch production.
- Reduced operator error and fatigue.
- Improved surface finish by eliminating over‑travel.
- Easy firmware updates via USB for future enhancements.
How It Works
The probe’s stainless‑steel tip contacts the workpiece or a calibrated touch plate. When contact is made, the sensor sends a signal to the controller, instantly setting the Z‑axis zero point. The built‑in auto‑zero routine then verifies the measurement, ensuring flawless tool changes and multi‑pass operations.
