How to know whether E-value means "filament length in mm extruded" or "filament volume in mm^3 extruded"?

Recommended Posts

Hey there,

I would like to know if it is possible to see from the plain GCode whether the E-value refers to the volume of extruded material [mm^3] or to the length of filament that is drawn into the extruder [mm].

I have read through a couple of posts here and found both interpretations of the E-value. It would do me a great favor if somebody could shed some light on this as I have been struggeling with this question for quite some time.

Thanks a lot in advance!

Best,

Peter

It depends of the gcode flavor you have set. If you haven an UM2, then Cura is set to "UltiGcode" where values are in mm^3. Regular gcode refers to mm of filament.

You can set the gcode flavor in Cura in the menu -> "Machine" -> "Machine Settings" -> "Gcode flavor".

Well there are several ways to tell. One way is to check for if the temperature is set. Only reprap mode sets the temperature (near the top of the file) of the nozzle (and also the bed if you have it). I think there are other ways if you look at the comments.

Also realize that if you are in cura you can go to the file menu and choose "load profile from gcode...". Every gcode file has all the settings encoded at the bottom - cura can read this and set all your settings to those values then you can go through leisurely through all the cura menus and see what the settings were at when you created the file but I don't think it will tell you if it was ultigcode mode or reprap mode. But everything else is in there.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
