Cura filement usage v duet
-
Hi , I
m printing a test print with Cura which says that it will use 12 metres of filament , but duet says 32 metres . Ive tried the E Step calibration test which looks to be about right ?
I`m using a titan aero , which is using a 3:1 gearing so is it calculating the filament based on stepper motor steps ? -
Duet uses relative extruder moves by default (M83).
Cura uses absolute extruder moves by default (M82), are you sure both are setup the same? -
That 12:32 happens to be the ratio of 1.75 to 2.85 squared so I suspect that Cura thinks the filament is 2.85 dia.

The Duet gets the filament usage from a comment that Cura wrote near the end of the GCode file.

That seems more plausible, the OP did not specify if actual the print was OK

Yes it printed more or less correct a little Z axis problems with a layer slip , but not that bad for a set up print.
I checked cura, Printer Machine > extruder1 , 1.75mm filament which is correct and a .4mm nozzle.

o.k looked at the gcode in a text editor and what it says at the bottom of the screen is different to what`s imbedded !!!!
