CNC Z Axis Touch Plate Tool Height Setter for Router Mill Engraving, Fast Auto Tool Zero Setup

CNC Z Axis Touch Plate Tool Setting Probe (Model Z axis) Overview A compact, easy to use touch plate designed for fast and repeatable Z axis tool height setting on CNC routers and milling machines. The probe is constructed from wire and metal for reliable electrical contact and straightforward hookup. Key benefits Speeds up tool height setting and Z zeroing for faster machine setup. Provides repeatable contact detection to reduce setup variability. Simple wiring and software setup that works with many CNC controller systems. Specifications Material: wire and metal Overall size: approx. 3.5 x 2 cm (D x H) / 1.38 x 0.79 inch Effective contact surface diameter: 25 mm / 0.98 inch Cable length: approx. 125 cm / 49.21 inch (including alligator clips) Model number: Z axis Application: for CNC router and similar milling machines Connection and setup Two connection options: 1. If your interface board has a limit switch or probe input, connect the probe to that port. 2. If the interface board lacks that port, connect to the driver board limit switch port. In your controller software enable the probe and assign the correct input pin, then configure AutoToolZero. Example menu path: Config Ports and Pins Input signals enable Probe and set the pin number. The included example code can be edited to match your setup. Basic wiring and operation Connect the probe wire to the control panel interface. Attach the alligator clip to the control board GND (negative). Clamp the tool with the clip or hold the tool so it will contact the touch plate. Lower the tool until it contacts the plate; the probe detects contact and completes the measurement. Practical use scenarios Initial setup: Rapidly establish Z zero when installing a tool before cutting a job. Tool changes: Verify tool length after a tool change to maintain consistent part depths across operations. Multitool jobs: Automate Z probing between tool changes to reduce manual measurement and keep production running smoothly. Compatibility and notes Works with many CNC controller software packages that support a probe input and AutoToolZero. Cable includes alligator clips for easy grounding and tool connection. The probe contact area is 25 mm diameter, suitable for standard tool tip contact. This touch plate provides a straightforward, lowcost method to improve Z axis setup consistency and reduce manual measurement time on CNC routers and milling machines.
