Hi.
I have just moved form Slic3r over to S3D with my Solidoodle 3 with a E3Dv5 nozzle, and the S3D software looks really nice.
But I have some trouble getting with "thin wall" calibration.
In Slic3r I'm able to print a single wall that is exactly 0.42mm thick, and solid walls, but I'm really struggling with this i S3D.
The closest I have been in S3D is 0.58mm, but then it's not solid, and I can see gaps in the wall(see picture: https://drive.google.com/file/d/0B6NYha ... sp=sharing)
When I try to decrease extrusion multiplier even further, the printer only prints small bubbles that won't stick to the bed.
My settings in S3D are:
Nozzle diamenter: 0.40mm
Extrusion width: 0.42mm
Extrusion multiplier: 0.50
Filament: 1.75mm.
Settings i Slic3r:
Nozzle diamenter: 0.40mm
Extrusion width: 0.42mm
Extrusion multiplier: 0.8
Filament: 1.75mm.
My calibration box: 0.5mm wall, 20x20x20 width

Any one got a suggestion what might be causing this?

Re: Gaps in thin wall / single line
You need to calibrate S3D differently than Slic3r. They are different programs and operate a bit differently. Here's how I would calibrate S3D:
1) get your bed leveled and the z-position correct. You can do this by going to tools -> bed leveling wizard, or by jogging around manually. But you just want to make sure that your first layer is printing correctly, and is properly squished, as that will affect everything else above it
2) once you have that figured out, go download this part (http://www.thingiverse.com/thing:34553). Note that this is a solid cube, which will be much easier to work with than the part you suggested
3) import that cube and then click "edit process settings". Go to the Layer tab and set "top solid layers" to zero, "bottom solid layers" to zero, and "outline/perimeter shells" to 1. Now go to Infill tab and set "interior fill percentage" to zero. This will create a perfect single outline print since you have no roofs or floors and no infill. I would also change your extrusion multiplier back to 1.0 to start.
4) once the print is done, measure the thickness of the single outline. Compare that value to the "extrusion width" on the Extruder tab. It should be fairly close, but usually a tiny bit larger (for example 0.44mm measured vs 0.42mm extrusion width in settings).
5) if the measured width is too large, decrease the extrusion multiplier on the Extruders tab. If it's too small, increase the extrusion multiplier
6) once the measurement is close enough, then try printing a part with 3 perimeters and make sure that each perimeter is properly bonding with the one next to it. If there are gaps between the perimeters then you are probably still under-extruding a bit. If they bond together but seem squished with visible ridges between them, then you might be over-extruding a bit.
Finally, once you are done with all that, try printing a normal filled in cube with 30% infill and 3 top and bottom solid layers. Hopefully, if you did everything right, you'll be looking at a great print!
