- | This article discusses the flatbed correction feature built into myCNC software which is often useful when the working table is not even or has certain spots which are higher or lower than the reference position. This is especially useful in cases when something like a tangential knife needs to go over the uneven table, with up to a millimeter of play being involved, resulting in a cut that does not actually go through the working material properly. | + | This article discusses the flatbed correction feature built into myCNC software which is often useful when the working table is not even or has certain spots which are higher or lower than the reference position. This is especially useful in cases when something like a tangential knife needs to go over the uneven table, resulting in a cut that does not actually go through the working material properly, or alternatively a cut that goes far too deep into the material. |

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. |

After the measurement procedure has completed and all the points are logged, select the Reference Z value. The Reference Z value should be chosen to be between the minimum and the maximum measure point, preferably somewhere in the middle between the two. | After the measurement procedure has completed and all the points are logged, select the Reference Z value.

- | //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.

Here, you have to edit the two lines with the EDIT THIS comments. In the input P, you have to specify the input number for the sensor (set as 15 in this example), and in the L field you have to specify the behaviour that will be interpreted as the sensor being triggered (0 for a normally closed sensor which will be opened when triggered, and 1 for a normally open sensor which will be closed at contact). | Here, you have to edit the two lines with the EDIT THIS comments.
