      I gave up searching so...

      • Do we use coasting when also applying pressure advance?

      I am happy with the duet now as I changed my hotend witch has some issues. Any tips on how to tune the retraction better?

      • Bowden 750mm cant be shorter
      • 6.5 mm retract
      • 40mms
      • 2000 Accel
      • 600 Jerk
      • Coasting on
      • No PA

        Do we use coasting when also applying pressure advance?

        No. Coasting attempts to reduce over-extrusion during deceleration; but pressure advance does it much better, as well as compensating for under-extrusion during acceleration.
