--uptodate
Refresh a 3MF's embedded config against current preset values before slicing, pulling non-customized settings forward while preserving any the user explicitly changed; companion flags --uptodate-settings and --uptodate-filaments name specific preset files, or omit them to refresh against the slicer's bundled presets instead.
Details
Refreshes the config values embedded in a 3MF against current presets before slicing, then slices with the refreshed config. A 3MF stores the settings that were active when it was saved, which drift from the latest presets over time; --uptodate pulls non-customized values forward from the preset source while leaving settings the user explicitly changed alone. It draws those updated values from its companions, --uptodate-settings (machine and process JSON) and --uptodate-filaments (one preset per filament slot, in order). Omit them and it refreshes against the slicer's bundled presets instead.
Watch out for
- ▲ Each supplied preset must match the name recorded in the 3MF (you cannot point it at a different machine profile), and the filament list must be exactly one entry per slot.
- ▲ It is distinct from `--allow-newer-file`, which only gates whether a newer-version 3MF is accepted at all; the two can coexist.
- ▲ Because it rewrites the config that feeds the slice, verify the result: values you expected to refresh may have been preserved as user customizations.
