Hi All, I'm new to 3D. I notice that the print show different Filament weight and length from the Cura slicer file but the Filament Manager is counted correctly.
Both Cura and Filament manager rely on the material density, which needs to be entered/configured. It sounds like you may have a unit wrong in one of the applications.
Filament manager is correct when it deduct the usage. If not mistaken Filament (Tool0) is under octoprint. I have confirmed that both Octo and Cura have the same setting, density 1.24, diameter 1.75.
