Possible to view w/t ratio in generated gcode?

[crispy1 0]

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}

Are you asking for width over thickness? We don't use that anymore, it's silly, backwards and as long as you have a step extruder you don't even want it. I also don't need to calculate it because the SF version in Cura doesn't use it.

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.

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:

So in the words of the pseudocode on your page, is it possible to get Cura to print the lineWidth variable into the gcode?
