 By adding these correction points, myCNC software will create an updated Z-axis map of the working table. From here on, whenever Flatbed Correction is enabled, the machine will automatically adjust the z-axis height of the working tool in order to adjust for the table level changes depending on where in the XY-plane it currently is. By adding these correction points, myCNC software will create an updated Z-axis map of the working table.
