CuraEngine in command prompt

[snsamonte 0]

I tried calling CuraEngine.exe in the command prompt but I got this error:

ERROR: Failed to load json file: fdmprinter.json

Unregistered setting machine_end_gcode

Unregistered setting speed_travel

maxObjectHeight : 0

M107

G0 X0 Y0 Z5

How can I fix it? And, is it possible to open, and compute printing time of STL files this way?

Your best option would be to do it in Cura and debug the python code to see the exact command that is sent.
