<p>You may wish to stop the print early if it is clear extrusion has ceased or become unreliable. This may prevent the need for disassembly of the extruder to clear the blockage.</p>
<p>Some slicers support using the calculated volumetric flow rate above as a hard limit. For those that don't, you can use the following calculator to reverse engineer a maximum feedrat for your preferred extrusion width and layer height:</p>
