      For the last 4 days i have been struggling with a clicking noise from my new extruder. Also had rough layers.
      It is a E3D Titan with bowden and I bought their motor also and while I was at it I upgraded the hotend to the V6.

      What did I do wrong, I shall explain.
      Even though I calibrated the E steps, leveled the bed too many times to count, wrote numerous drafts to post on the forum, lots of failed prints and a shed load or swearing, it eventually clicked, i had missed one step.
      Even the retraction test worked fine with no stringing but there was some clicking.
      In Cura they call it 'Flow', in others i think it is called Extrusion Rate.

      Just because you have your E steps correct does not mean that it will print perfectly.

      Resolution
      Found the 25mm cube I used when I was on Marlin firmware, printed it, took 8 measurements, divided by 8 and gave me my average wall thickness in my case 0.6. My Nozzle dia 0.4 = 0.8 wall and current 'Flow' was 100%
      So 0.8 / 0.87 * 100 = 91%

      Now as opposed to .7 and 0.9 mm walls i am down to .05mm consistantly which has made me happier.

      Put the new setting into Cura and over extrusion, lifting from bed and mainly the swearing has been rectified.

      So hopefully I should be able to print a little faster

      The Link I used was this, http://www.thingiverse.com/thing:3397997
      Look at the readme.txt for the manual.

      I appreciate most of you know this already, but just incase someone is struggling it may help them.

      RailCore II - Duet Mini + 1LC, Voron V0.1 - Duet Mini
      Voron 2.4 disassembled..... Waiting for the RailCore Mini....

        @paulhew Is it grinding the filament? On my printer I had to increase the hotend temperature a bit.

          i had the same thing happen on my bmg. had to reduce to about 90% for the correct accuracy.
          I never worked out where that difference came from between the correct e steps and the resulting flow.
