I've gone ahead and published the guide Retraction Tuning With Slic3r on the Tutorials --> Slic3r Tutorials Wiki page.

I'm quite familiar with ways of doing all this by inserting gcode, but not for all of this for all firmware. As always, if I've made an error, please let me know.

Hope that helps!]]> Paul Wanamaker Printing Tue, 26 Jan 2016 03:24:43 -0500 https://reprap.org/forum/read.php?262,615163,615689#msg-615689 https://reprap.org/forum/read.php?262,615163,615689#msg-615689 Koby_88 Printing Tue, 26 Jan 2016 01:28:04 -0500 https://reprap.org/forum/read.php?262,615163,615502#msg-615502 https://reprap.org/forum/read.php?262,615163,615502#msg-615502 Every time you start a new outside run it will leave these little blobs.
For simple designs like the one in your pic you actually don't need retraction at all ;)
Might be worth a try....]]> Downunder35m Printing Mon, 25 Jan 2016 14:33:28 -0500 https://reprap.org/forum/read.php?262,615163,615280#msg-615280 https://reprap.org/forum/read.php?262,615163,615280#msg-615280 Koby_88 Printing Mon, 25 Jan 2016 06:15:38 -0500 https://reprap.org/forum/read.php?262,615163,615275#msg-615275 https://reprap.org/forum/read.php?262,615163,615275#msg-615275 Plasteroid Printing Mon, 25 Jan 2016 06:03:15 -0500 https://reprap.org/forum/read.php?262,615163,615163#msg-615163 https://reprap.org/forum/read.php?262,615163,615163#msg-615163 Koby_88 Printing Mon, 25 Jan 2016 01:06:16 -0500
