 <p>一些切片软件宣传有 "高级挤出机压力调整 "的功能。建议在使用 Klipper 时禁用这些功能，因为它们很可能会降低打印质量。考虑使用 Klipper 的<a href="Pressure_Advance.html">压力提前</a>代替。</p>
 <p>具体来说，这些切片软件的设置生成的命令会固件对挤出率进行剧烈的改变，希望固件能接近这些请求值，使打印机获得一个大致理想的挤出机压力。然而，Klipper利用精确的运动学计算和计时。当Klipper被命令对挤出率进行重大改变时，它将计划出速度、加速度和挤出机运动的相应变化--这不是切片软件的意图。切片软件甚至可能产生过大的挤出速度，以至于触发Klipper的最大挤出截面检查。</p>
 <p>相反，使用切片软件的"回抽"、"擦拭 "和/或 "缩回时擦拭 "设置通常是有益的。</p>

+<p>When using a START_PRINT macro or similar, it is useful to sometimes pass through parameters from the slicer variables to the macro.</p>
+<p>In Cura, to pass through temperatures, the following start gcode would be used:</p>
+<div class="highlight"><pre><span></span><code>START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0}
+</code></pre></div>
+
+<p>In slic3r derivatives such as PrusaSlicer and SuperSlicer, the following would be used:</p>
+<p>START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]</p>
+<p>Also note that these slicers will insert their own heating codes when certain conditions are not met. In Cura, the existence of the <code>{material_bed_temperature_layer_0}</code> and <code>{material_print_temperature_layer_0}</code> variables is enough to mitigate this. In slic3r derivatives, you would use:</p>
+<div class="highlight"><pre><span></span><code>M140 S0
+M104 S0
+</code></pre></div>
+
+<p>before the macro call. Also note that SuperSlicer has a "custom gcode only" button option, which achieves the same outcome.</p>
+<p>An example of a START_PRINT macro using these paramaters can be found in config/sample-macros.cfg</p>
