The xsTECH, powered by Tormach's PathPilot® software, is a versatile CNC machine perfect for classroom settings. In Part 2 of our three-part series, Domenic Giunta, Tormach EDU sales advisor, guides us through the setup and use of the electronic tool setter (ETS). This tool streamlines the process of calibrating tools, ensuring precision and efficiency for educators and students alike.
What Is the Electronic Tool Setter?
The ETS is a device designed to simplify tool calibration by accurately measuring tool lengths and positions relative to the machine's spindle and workpiece. This setup minimizes errors and eliminates the need to manually recalibrate tools during projects, making it an essential feature for educational environments where precision and ease of use are paramount.
Installing the Electronic Tool Setter
To begin, ensure your xsTECH is referenced and ready. Navigate to the probe section in PathPilot, and select the ETS setup menu. Install your first tool — a tapered end mill (tool #39165)—using the provided collet and wrench set. Safety is crucial in classrooms, so handle tools carefully to avoid injuries. Tighten the tool just enough to secure it without overdoing it, as excessive force can damage the collet or tool.
Next, mount the ETS to the machine using its T-nut. Position it in the machine's corner to ensure it's aligned with the spindle. Adjust the tool so the point aligns with the ETS button. This precise positioning ensures the machine recognizes the ETS' location for future use.
Setting Up the Tool Length and G37 Position
With the ETS installed, calibrate the machine's spindle and tool length. Start by referencing the spindle. PathPilot’s intuitive interface will guide you through the process, ensuring the spindle is aligned with the ETS button. Set the G37 position, which serves as the "home" location for the ETS. This step is critical for establishing a consistent reference point, simplifying future tool changes.
After setting the spindle, measure the tool length using the ETS. PathPilot automatically calculates the tool's length, storing the data for use in subsequent operations. This feature is particularly useful in classrooms, where tools are frequently swapped for different tasks.
Why the Electronic Tool Setter Is a Game-Changer
The ETS enhances workflow by eliminating the need to recalibrate tools each time they’re changed. For example, educators can use a large tool to remove significant material and then switch to a smaller tool for detailed work without manually resetting the Z height. This automation saves time and reduces the margin for error, ensuring students focus on machining rather than troubleshooting.
By simplifying tool calibration and streamlining workflows, the ETS empowers educators to teach CNC concepts with confidence.
What’s Next in the Series
Now that you’ve mastered the ETS setup, the next step is to establish the machine’s origin and configure the X, Y, and Z zero points for milling. Come back next week for Part 3 of our series, where we’ll dive deeper into setting up for precise and efficient machining projects.
