Probing

Probing is the process of determining and setting the origin point on a workpiece, or measuring the length of a tool loaded into your CNC. Accurate and consistent probing leads to accurate and consistent results.

MillMage Probing Wizard

MillMage supports two types of automatic probing processes:

  • XYZ Probing, which determines the zero point on your workpiece in up to three dimensions and applies an appropriate work offset.
  • Tool Length Probing, which measures the length of a tool loaded into your CNC and applies an appropriate Z Axis offset. This is typically used after a tool change to update a Z Axis offset without re-zeroing on that axis.

In this guide, you'll see examples of both types of probing using CNC tools and accessories. Some CNC machines include built-in probing locations for Z Axis zeroing and tool length determination, while other models require additional accessories.

Because every CNC machine is different, and the material stock you use will vary with each project, the appropriate probing method may be different or unique to each project.

Probing Wizard Overview

MillMage includes a Probing Wizard that will walk you through setting up a probe block or tool length probe. First time Probing Wizard users must define the dimensions of the probe block or location of tool length probe before continuing with the probing wizard.

This page has a brief overview of the probing process, with more detailed guides available on the pages for each probe type.

Defining Probes

Window for selecting probes to edit

To define your probes, go to CNC ToolsProbe Settings, or click the Manage Probe Configuration button in the Probing Wizard.

Select either the XYZ Probe Block or the Tool Length Probe to edit.

XYZ Probe Block

An XYZ Probe Block sits on a corner of your workpiece and is used to define the workpiece origin. To set up a Probe Block:

  • Use calipers to measure the offsets and enter them as Offset X, Offset Y, and Offset Z.
  • Set the search distance – the distance the tool will travel in each axis while probing – in Search X, Search Y, and Search Z.
  • Set the Probe Depth – the distance the tool will move below the surface of the probe when probing the X and Y axes.
  • Set the probe feed rates.

For more information, see XYZ Probe Block.

Tool Length Probe

A Tool Length Probe measures the length of your tool, allowing you to use tool offsets when changing tools. To set up a Tool Length Probe:

  • Set the location of the Tool Length Probe relative to the machine origin in Position X and Position Y.
  • Set the Search Z value to the maximum distance the tool should travel downward when searching for the probe.
  • Set the probe feed rates.

For more information see Tool Length Probe

Using Probes

Open the Probing Wizard by selecting CNC ToolsProbing Wizard, or by clicking the Probing button in the Move window.

Select the type of probe you'll be using.

XYZ Probe Block

Warning

Don't forget to make sure your probe block is connected properly and responds as expected when in contact with the tool.

To use the probe block:

  1. Select the axes to probe.
  2. Use the jog and position controls to make sure your tool is at an appropriate location over the probe block.
  3. Enter the Tool Diameter and check other probing settings.
  4. Click the Execute X, Execute Y, or Execute Z button to probe a single axis, or Execute on All to probe all three axes, starting with Z.
  5. The origin in the workpiece coordinate space should now be set to the corner of your workpiece.

For more information see XYZ Probe Block

Tool Length Probe

To use the tool length probe:

  1. Check that the travel path toward your Tool Length Probe is clear.
  2. Click Execute Tool Length Probe. MillMage will execute the GCode shown in the Probing Wizard window.

Remember — because every CNC machine is different, the method of Z Axis probing you use depends on your CNC machine and available accessories.
