These values can either be recorded by using the AutoMeasure procedure, or by using a sensor and recording each point individually by using the M402 macro. Using the AutoMeasure procedure, the operator can set the measurement distances for the X and Y axes as well as the number of points at which the height measurements will be taken for the XY-plane.

-    * //NOTE: The myCNC flatbed correction feature is limited to 1000 pulses (+ or -) from the Reference Z position. Depending on the number of pulses per unit that you have set up in the Axes/Motors window, this may be anywhere from a centimeter to a fraction of a millimeter. If the machine moves above or below the 1000 pulses limit, it will not be able to accurately correct for flatbed distortion until it is back down below the limit. This is why the reference Z value must be selected correctly. // +    * **Note:** The myCNC flatbed correction feature is limited to 1000 pulses (+ or -) from the Reference Z position.

   * In order to use the M402 macro for manual point measurement, move the sensor to the position you want to measure, then press the **Measure (M402) and Save** button. This will lower the sensor down until contact, then lift it back up and record the z-position at which the sensor was triggered.    * In order to use the M402 macro for manual point measurement, move the sensor to the position you want to measure, then press the **Measure (M402) and Save** button.
