I’m using the Planetary gear model as a reference (http://www.thingiverse.com/thing:23030/#files), specifically the part at scale 150% which holds the 3 planet gears in place with 3 thin shafts. When printing at 0.15 layer height the base comes out beautifully but as it comes to the thin shafts it appears to spit out a too much filament then proceeds to plow the head through the excess plastic.
I’m using all the slic3r configuration files with the same results. It still happens with default slic3r settings with 0.3 layer height but it’s less obivous.
I have tried to reducing solid and top solid infil extrusion width to prevent the extra squirt on the fine shaft, and increasing the distance in my Z end stop to give it some extra space to the point where the first layer hardly sticks on the bed.
What other options do I have besides printing at 200% scale?
