I just finished a print that had an estimated material usage in Cura (v4.8.0) of 412g but the actual material used is 290g. What would cause this/How do I fix it?
I have been 3D printing for a few months now so I'm fairly comfortable with it. My print settings are pretty dialed in and are producing beautiful prints at 0.12mm layer height with PETG. I have also created a custom profile for the Overture PETG that I am using and I feel as though it's spot on. Switching the selected material to the generic PETG increases the estimated material usage to 437g.
Custom Material Settings:
Density: 1.30 g/cm3
Diameter 1.75mm
Filament weight 1000g
Filament length: 320m
I am using a Ender 3 V2 and the only major upgrade is a dual gear extruder that required me to increase the extruder transmission ratio from 93 to 139.1 (33% increase). Is this the cause? If so, is there any way to reflect this change in Cura? I have been unable to find any such setting, but maybe I'm not looking in the right place.
The time estimates are also pretty close as that print was estimated to take 2d5h and actually took about 2d3h so that's not a problem. My biggest issue is I'm printing a large project that takes multiple spools and an accurate estimation prevents wasted filament on the spool.
Any help would be greatly appreciated.
