@@ -234,9 +234,9 @@ the pressure necessary to extrude is dominated by the flow rate
through the nozzle orifice (as in
[Poiseuille law](https://en.wikipedia.org/wiki/Poiseuille_law)). The
details of the above physics are not important - only that the
relationship between pressure and flow rate is linear. It is expected
that an appropriate "pressure advance" value for a particular filament
and extruder will be determined experimentally.
relationship between pressure and flow rate is linear. See the
[pressure advance](Pressure_Advance.md) document for information on
how to find the pressure advance coefficients.
Once configured, Klipper will push in an additional amount of filament
during acceleration and retract that additional filament during
