CuraEngine mesh_rotation_matrix to rotate 180 degrees

Hi,

I am trying to rotate an object before slicing using CuraEngine.

However, if i try to rotate 180 degrees (-s mesh_rotation_matrix="[[1,0,0],[0,-1,0],[0,0,-1]]") slicing fails.

Without rotation slicing works as expected

Snippet of the output:

"

Progress:inset+skin:1:1 0.276473%

Layer count: 1

Progress: inset+skin accomplished in 0.000s

Starting support...

Removing 1 layers because they are empty

Stopping process because there are no non-empty layers.

Progress: support accomplished in 0.000s

Starting export...

;FLAVOR:Marlin

;TIME:6666

;Filament used: 0m

"

Is there anyone who has an idea what I'm doing wrong. Or is this a bug in CuraEngine?

    Just a WAG here, but since the print origin is at the corner of the print bed (unless you're using a Delta printer), and the rotation matrix is rotating about the origin, then haven't you just rotated it off the print bed?

    Try changing your rotation matrix to rotate about the center point of your object.
