<p>许多探头容易出现“漂移”,即:由于热或干扰而引起的探头不准确。这使得计算探测器的z偏移量具有挑战性,特别是在不同床温的情况下。因此,一些打印机使用端止器来定位Z轴,并使用探头来校准网格。在这种配置中,可以对网格进行偏移,从而使(X,Y)<code>参考位置‘应用零点调整。‘参考位置’应该是床上进行[Z_ENDSTOP_CALIBRATE](./Manual_Level#calibrating-a-z-endstop)试纸测试的位置。Bed_Mesh模块提供了</code>ZERO_REFERENCE_Position`选项来指定该坐标:</p>

<p>By nature, adaptive bed meshes use the objects defined by the Gcode file being printed. Therefore, it is expected that each Gcode file will generate a mesh that probes a different area of the print bed. Therefore, adapted bed meshes should not be re-used. The expectation is that a new mesh will be generated for each print if adaptive meshing is used.</p>
|
||||
<p>It is also important to consider that adaptive bed meshing is best used on machines that can normally probe the entire bed and achieve a maximum variance less than or equal to 1 layer height. Machines with mechanical issues that a full bed mesh normally compensates for may have undesirable results when attempting print moves <strong>outside</strong> of the probed area. If a full bed mesh has a variance greater than 1 layer height, caution must be taken when using adaptive bed meshes and attempting print moves outside of the meshed area.</p>
