    The arms issue is called "overhangs" and you can fix that somewhat with support.  Personally I would enable support touching buildplate only for this model.

     

    Was this one thorn worse than all the others?  If so it's probably related to "z seam".  By default it's on "sharpest corner" but that's probably this particular thorn so try "random" or any of the other options.  Make sure your fan is at 100% and consider lowering the temperature by 10C and printing slower (try half the speed you did and I think it will help the quality quite a bit).

    This particular thorn was worse than the others, so I will try changing the z seam. The other thorns all had blobs, is this due to overheating? Thanks

    This is called a torture test for good reason.  The filament doesn't get much time.  You want to set the travel speed as fast as possible but it's going to string a little no matter what.  These strings are pretty easy to remove by hand.  One thing you can try is lowering the temperature.  A lot.  Maybe even as low as 180C  but be careful as the filament gets more viscous and you might get underextrusion if you print too fast at 180C.  You could also print with a smaller nozzle such as the .25.  Make sure fan is at 100% but that's the default so you can't do much there.

     

     

    I tried lowering the temperature to 185C, and still had stringing, but it was less than previously. I am looking at "Retraction Extra Prime Amount" on Cura, and notice that by default it is set to 0 mm^3. Should I leave this unchanged, or do you have a recommended volume?

  3. Hello, I am new to 3D printing and am currently optimizing my Ultimaker 2 Extended+ using Cura. (2.85mm PLA)

     

    I am in the process of changing retraction settings, but am having trouble. I am currently printing pillars, but keep running into the same issue. As the pillars get taller, they get thinner at the top, and my printer ends up printing the tops too fast, causing stringing. I'm not exactly sure which setting I can change to make the tops print slower. Any advice?
