Ah, that makes sense, thank you. I'm trying to follow the calibration steps here, because in my experience it is the easiest and most reliable way to get the flow rate correct: https://github.com/alexrj/Slic3r/wiki/Calibration So in the words of the pseudocode on your page, is it possible to get Cura to print the lineWidth variable into the gcode?

I need some way of seeing what single wall thickness Cura is using. In other words, if Cura lays down a single bead of plastic, what will the width of that bead be? I can make a simplistic assumption about the single wall thickness based on the "Wall Thickness" field (eg if I enter 1.2 and the gcode has 2 perimeters then single wall thickness is probably 0.6) but I would really prefer it be stated explicitly in the gcode as a comment.

Double post

Is it possible to read the calculated w/t value and put it into the start gcode as a comment? What is the variable name I need to use to do this? Something like: ;calculated w/t is: {wt_var}
