    i activated lin adv and my print speed has dropped considerably ... my print time etas are off..
    print of 34mins went to 49mins with lin adv..
    how can i get my speeds back?
    sliced a print at 60mm/s printing.
    i reckon its 30mm/s.
    any ideas???

    I have an anet a8 and do you think it's normal for my K value to be at 75? It seems higher than everyone elses but it did look best after the K calibration test at

      It depends on your type of setup (bowden/direct) and your filament. My bowden setup uses even higher values. But if it's running fine... :-D

      QD2MAX I did read about that and I'm not using a Bowden so I guess it's fine haha. I did notice that while printing I was hearing the extruder click like it was empty but it in fact was able to print fine which was odd and I haven't noticed it since.

      Because of the linear advances noise, I constructed a new extruder, I'm using now. www.thingiverse.com/thing:2812602

      Hi, I am using the following settings:
      #define DEFAULT_ACCELERATION 800 // X, Y, Z and E acceleration for printing moves
      #define DEFAULT_RETRACT_ACCELERATION 600 // E acceleration for retracts
      #define DEFAULT_TRAVEL_ACCELERATION 1000 // X, Y, Z acceleration for travel (non printing) moves
      #define DEFAULT_XJERK 10.0
      #define DEFAULT_YJERK 10.0
      #define DEFAULT_ZJERK 0.4
      #define DEFAULT_EJERK 5.0
