How to Use the Z-Probe (Auto Tool Zero) – Step-by-Step Guide

Using the Z-Probe (Auto Tool Zero Device)

When machining flat plate materials, the Z-probe (also called an auto tool zero device or touch plate) helps you perform Z-axis tool setting quickly and conveniently. However, you must strictly follow the operating steps below; otherwise, the probe or the cutting tool may be damaged.

Step-by-Step Instructions

  1. Insert the Z-probe and measure its thickness.
    Plug in the Z-probe cable. Measure the actual thickness of the touch plate using a caliper, and enter that thickness value into MACH3 (in the appropriate settings field).
  2. Test the Z-probe (perform this test every time before actual use).
    Turn on the POWER switch. Clear the X, Y, and Z axes to zero. Click the "Auto Tool Zero" button in the software interface. The Z-axis will slowly move downward. Briefly touch the metal clip to the surface of the touch plate — the Z-axis should stop moving down and then rise by 10 mm. This confirms the probe is working............
