During a CS lesson, I'ld like the students to generate a gcode so that they can print their results on a UM3.
I'm making some tries, but their seems to have some issues.
I've look at this post that gives what should appear in the header. But it seems that there must also a ender mandatory, as after the first print, the printer had trouble to print anything. So using Cura, I've generate a gcode to try to mimic it. Are the last 18 lines mandatory (see in the test.gcode file)?
Also, I'll like to know how the quantity of filament to extrude is computed (the E value)? I guess it depends on the distance traveled and the speed, but the ratio I've computed doesn't give a nice result, as you can see on the picture :(.
