CuraEngine 3.4.1, 3.5 flat models: 0 print time, 0 filament used


Recommended Posts

Posted · CuraEngine 3.4.1, 3.5 flat models: 0 print time, 0 filament used

Description
When slicing flat models (test.stl attached) I get 0 print time and 0 filament used (test.log). However if I rotate the same model by 90 degrees (test_rotated.stl) to make it taller I get reasonable results (test_rotated.log).
In GUI Cura everything's fine, although even if I copy all the -s parameters from cura.log I still get the same problem.

Am I missing something here?

Application Version
3.4.1
3.5

Platform
Linux

Steps to Reproduce
Take the attached test.stl 

Run:

CuraEngine slice -v -j '/usr/share/Cura/resources/definitions/fdmprinter.def.json' -v -o /dev/null -l test.stl

Actual Results

CuraEngine 15.04: (good!)
Print time: 14206
Filament: 13965

 

CuraEngine 3.4.1: (error)
Print time (s): 0
Print time (hr|min|s): 0h 0m 0s
Filament (mm^3): 0

 

CuraEngine 3.5: (error)
[ERROR] Unknown exception.

Expected results
Print Time > 0
Filament > 0

 

test.stl

test_rotated.log

test_rotated.stl
