Description

Hi, I noticed that the flushing volumes matrix in the 3MF files generated with this library is incorrect and contains the default value (280). As a workaround, the user can click “Recalculate”.

I’d really appreciate a fix for this.

Anyway, this library is fantastic. I’ve decided to become a donor, thank you! 😊

Research direction

Start by locating the code that generates 3MF files and builds the flushing volumes matrix. Reproduce the export and inspect why the matrix contains the default value 280 instead of the intended values. Done means generated 3MF files contain the correct matrix without requiring the user to click “Recalculate”.
