    Does pressure advance (M572) work both ways?

      Hi,

      I'm still quite far behind with the firmware releases, so I still haven't got back to experimenting with pressure advance, though it is soon on my list of things to do.

      I know that the pressure advance will retract the position of the E axis when going from a fast extrusion move to a slower one (or none at all).

      Will the algorithm also advance the E position when going from a very slow extrusion to a very fast extrusion?

      I've noticed (without any M572 value) that when the toolpath goes from very slow outer perimter to fast infill, it takes a half second or so to get full extrusion happening. Will Pressure advance help that?

      Thanks!

          Well, pressure advance is even better than I originally thought! I need to update my firmware ASAP. Thanks.
