Ok. I can send the command from windows cmd to slice the file. I have done it and create a gcode file. And then send the command to open cura the gcode file. This is almost there i believe is good enough. It would be nicer if i could get the print info (estimated time, weight of object and cost) do they stored somewher? I cant find them in gcode file.somewhere else maybe where i can have access? I want to find them and send them through a web service.
