Stretchlet slicing totally borked on OSX

[jonathanberi]

Hi all! I'm testing out Simplify3D on a recommendation but come for 1 year+ slicing with Slic3r. I must admit, initial results are not good but still willing to see if I can work through it (already one detailed crash report sent!)

I'm trying to use print the famous Stretchy Bracelet on my Wanhao Duplicator i3. Slic3r outputted gaps in the g-code when I tried slicing it. Here's the output:



With a 1.1 scale I was able to print it nearly perfectly (maybe there's a wall thickness issue?):



On Simplify3D using the standard Wanhao Duplicator i3 process all the features are lost:



And scaling changes but really doesn't improve things:



Any ideas? I'm not giving up just yet but wondering if this software is ready for primetime on a mac. Hopefully it is just a n00b error!

That's because the bracelet is thinner than the extrusion width that S3D is set to use. However, there's an easy way to still print it. Just download the "stretchlet1.stl" file from here (it's the solid one, not the hollow one)

Then open your process settings and use 1 perimeter outline, 0 top and bottom solid layers, and 0% infill. That way it will just print a single ring around the outline. You could even enable vase mode if you want.

And if you ever have this scenario where you don't happen to also have a solid version of the model, you can also go to the Advanced tab and enable the "merge all outlines into single solid model" option, which will essentially do the same thing.

yes i have tried this model before as well and can verify everything carl said. i checked the model a long time ago and the wall thickness on this is definitely thinner than a standard extrusion width from a .35-.4 nozzle. it seems the people that have the hardest time with s3d are the ones that have come from another slicer that they have used for a long time. very little will transfer from slic3r or any other slicer to s3d. you basically need to relearn everything. the math is all different from slicer to slicer so setting values are completely different. give it time. you'll work it out and get it working for you.

@CompoundCarl merge all outlines did the trick, thanks! Time to try more pesky designs to get the hang of this thing.
