Printed an ornament with my M301. Starting to get some decent prints but getting lots of strings as shown in the second photo. First photo shows a quick effort at removing some of the strings. Printed at 190 deg except for a little near the bottom at 200 and 210 which made the strings worse. 1 mm retraction was used which slowed the print considerably. Sliced with Slic3r; I may try Cura or look for settings that avoid crossing outside perimeters.
