Cura 13.06.5 (Mac) fails to slice thin wall calibration object

[Nicolinux 288]

There seems to be a problem with the latest official version. When I try to slice this object, it just says "0" for minutes, meter and gram. It creates an almost empty .gcode file where the body with the movement and extrusion instructions is missing. There are only comments with the layer number instead.

I tried different combinations of infill, shell thickness and bottom/top thickness but it still fails.

If you had posted this 12 hours ago I could look at it but I am away from home for 3 days so I can't open the STL. But I see the name mentions .5mm wall.

Just as a quick test, try setting your nozzle width to .2mm. See what happens in layer view in cura.

With a .4mm nozzle you can't print anything smaller than .8mm thick in X or Y.

Cura is currently not designed to handle the corner case single extrusion thin walls.

Weird, I thought that smaller nozzles were able to print small perimeters. If my nozzle can realistically do .2mm, then for 5mm it would take roughly two perimeters. But since Daid said that it is not designed to do so now, I'll accept it.

I just wanted to print this single wall object to check the wall alignment and as a quick & dirty test for z-wobbling.

For now, I am using this object instead:

I recommend making a solid cube and set the top/bottom and infill to 0.

Thanks, I did it.
