Pressure advance issues

Thanks DC42. Perfect explanation.

That's all correct. You don't need very high extruder acceleration for printing moves (and pressure advance doesn't affect the acceleration for retract and un-retract moves); however 200mm/min extruder jerk is unusually low, so the associated acceleration limit for printing moves that it causes might have an effect.
Sorry to dig up an old thread but I am just now configuring my own pressure advance. What would you recommend for extruder jerk with a 3:1 gear bowden extruder and a ~60cm long bowden tube?

I am also tuning the Pressure Advance. I have found a a K-factor calibration guide for Marlin at http://marlinfw.org/docs/features/lin_advance.html and a G-Code pattern generator in http://marlinfw.org/tools/lin_advance/k-factor.html.
Will this approach work for Duet?.
