Cura UI slice progress bar read data from CuraEngine

[leonardo-aguiar 1]

I have a simple browser based interface that uses php's exec function to run CuraEngine on an stl file that a client uploads. It is based on the source code provided by Jesse Campbell in his 3dpartprice.com site. I am looking for a way to make a progress bar of the slicing process. Does CuraEngine output data about the slice progress? The Cura app with a GUI has a progress bar that updates while the model is being sliced. What data is driving this progress bar? Any suggestions of different approaches to get a progress bar from CuraEngine's slicing process?

Your browser interface uses the 'command line' interface of CuraEngine. Cura itself does not use the commandline to communicate with CuraEngine. Cura starts a single "server-like" instance of CuraEngine, and then uses a protocol based on Google Protobuf to communicate with that instance of the slicer. (ie: send meshes and settings, receive progress and sliced data).

 

Detailed progress information may not be available via the commandline interface.
