Anyone else seen Simplify3D do this? An open top test cube shows fine in the preview when imported, yet when prepared for printing it only wants to do the bottom layers. The start and stop values are empty, so it’s not that I’m clipping it.
Dumb question. What line width is set. If this is the hollow calibration cube, and extrusion width is thicker than wall width it won’t print it. Second question. What are your perimeter and top fill settings at?
Is the wall thickness of the cube less than the configured nozzle width?
It’s best to use a solid cube model and print with n perimeters at n width, n bottom layers, 0 top layer and 0 infill
An open top cube like you’re describing is non manifold. The walls have no thickness. So the slice is interpreting a 0 thick wall perfectly. You need to either make those walls thicker (I recommend 2x your nozzle or 0.8mm in most cases) or cap the top and use vase mode.
Ok. Slic3r and Pronterface had dealt with it without problems and without needing to set vase mode.
I wish S3D could handle this. I’d hardly ever have a reason to use Makerware if it did.
Post the file and exported fff file. we can try it (those with S3d). Only screwy thing I have seen is the perimeters getting set to 0 because of a bug when you click the up / down arrow and it keeps going. For some reason it just leaves off the perimeter where I think it should at least use the infill to go out to the outer perimeter instead of leaving it off. Now that I think of it is it probably because S3D allows you to queue multiple processes you may want to leave off the perimeter on the second process if it is infill only related.
