Why is my surface finish comically bad?

Hello,

I'm printing with a Simple Metal fitted with an E3D v6, 0.4 nozzle. Been printing for seven months.

I've been mostly printing with Cura, but I saw the new version pop up, so I thought I'd see if I could get better results on some of the Make: shootout parts using Slic3r.
The results are more poor than I could have imagined - I'm using the same speeds, retraction, temps, and such in both slicers, so I was hoping someone could identify the culprit from the image attached. Slic3r is the left print, Cura on the right.

I used Slic3r when I first started for quite a while, and always got better results than this...

Unrelated, but 'Export .Gcode' doesn't seem to actually create a file in my target folder, even though I can see the 'ghost' of the exported file in the folder when I try to export again. Send to Octoprint printer works fine, so I could download the gcode to show the settings section:


Following is the relevant bits, I can post some code too if needed.

Thanks in advance for the knowledgable eyes! I'm looking forward to getting back into Slic3r! I hope I haven't violated too many forum rules and norms....

Okay, I'm seeing now that it's likely a nasty bug in 1.2.9 stable, so I'm going to try again with 1.2.7B and see if I can get the precision I remember.


Thanks again!
