Slic3r setup for smoother perimeters

Postby cgriffin » Sat Jan 10, 2015 6:49 pm

Using Slic3r.

I am (trying to) printing a small round knob; about 12mm in diameter. The OD, however, is not really round, but has a (relatively) large notch in it. I expect a knit line of some sort (to use an injection molding term), but rather than going all the way around and making a 90* turn in, it seems like the last 30-40 degrees it tapers in, causing a large wedge shaped blemish.

What is printing resembles the image on the left. What adjustments do I make to force it to go farther around, then take a sharper 90* turn, like the image on the right?

(For simplification, I have only drawn the outer perimeter, and skipped any infill.)

Thanks.

Please shoot me the .stl and we'll see what we can do. It is impossible to identify the root cause without having the file ourselves to manipulate.

Are you on slic3r v1.1.7, and did you heal the mesh?

Does it view properly in the .stl preview?

How does it look in the .gcode preview?

Thanks.

We don't see any problem with the .stl; send the gcode so we can compare to the gcode we generate, and see all of your settings.

Thanks,
