<p>The function of the tool setting instrument The measurement and compensation of the tool offset value in five directions can effectively eliminate the error and inefficiency caused by manual tool setting. No matter what kind of cutting tool is used for workpiece contour turning or milling, all tool tip points or tool axis lines involved in cutting must be adjusted or compensated so that they are accurately located at the same theoretical point or axis of the workpiece coordinate system on-line</p> <p>How to use:</p> <p>1.Alligator clip is fixed on the cutter</p> <p>2. port has been connected to the control board (A5 interface on the 3018pro control board)</p> <p>3.Place (plastic + aluminum plate) under the tool</p> <p>material: plastic</p> <p>Color as shown</p> <p>GRBL Z-probe CNC Router Tool Setting Automatic Tool Setter.
