Cura extrusion

[nobio8 2]

Hi,

latest Cura 2.6.2 gives this result:

Tube is 0.4 mm thick, layer 0.2 mm High, line with 0.4 mm

I tried PLA, ABS, PETG

Any suggestions ?

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.

When I use Slic3r to generate gcode I get normal print

Then I suggest you compare the temperature and speed settings of Cura and Slic3r.

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?

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 . . .

I adjusted the "Outer Wall Wipe Distance" to 0

and the result looks better. Fillament is PETG

Glad the Outer Wall Wipe Distance helped. Probably don't need the Draft Shield any more.

Did you reduce the Print Jerk and Travel Jerk?

You might also want to experiment with the "Z Hop" settings under the Travel Menu.

Solomon Islands huh? Sounds exotic. Maybe even idyllic?
