  1. sorry for delay, I solved the problem by the following procedure

    1. saved my Cura profiles and materials

    2. removed  all Cura installations

    3. Reinstalled Cura 3,6

    4. Imported back my Profiles

     

    Now it seems everything is just fine 

  2. smartavionics I sliced it again with your version of Cura

    and both Previews, Cura an Repetier's are the same no slicing

    error.

    I also imported my original GCODE (attached to my post)

    back to Cura 3.6 and preview shows errors correctlly.

    To summarise :

    1. 3.6 sliced my model with errors which are not visible in Cura preview

    when slicing

    2. If we preview GCODE in other slicers error is visible in all of them

    3. If we import the same GCODE back to Cura 3.6, preview shows errors

    as all other slicers

     

    We have two problems:

    1. Slicing with Cura has major errors

    2. We can not relay on Cura to preview the code correctly

    unless we import the G Code back again

     

     

  3. I adjusted the "Outer Wall Wipe Distance" to 0

    and the result looks better. Fillament is PETG

    That is the Z scar at layer change.

    Try adjusting the "Outer Wall Wipe Distance" to 0

    Set "Print Jerk" and "Travel Jerk" to 12 and 15 respectively.

    Play with the "Coasting" under the Experimental Menu.  Never did much for me, but worth a try.

    I have found that Cura 2.X.X has never done as smooth a job on the Z scar as the 15.X.X versions did.  However, I was using a UM2 Ext with the 15.X.X versions and a UM3 Ext with the 2.X.X versions.  So your results may vary . . .

  4. I created new stl file, now tube has a wall of 0.8 mm thickness instead of 0.4 mm.

    This way we get 2 lines instead of 1 and I also added draft shield which has only one line.

    Strange extrusion problem is now gone and the result is in the photo bellow,

    As one can see there is a gap at the point of direction change.

    How to eliminate the gap?

  5. When I use Slic3r to generate gcode I get normal print

    Maybe you want to clean the hotend as it looks like a partial clog to me. Make sure no leftovers from e.g. ABS are in the hotend when printing PLA. I recommend you start with a series of cold pulls.
