Orca shows these in Process > Others > Notes when exporting with a saved printer template. Without a template, use Copy notes and paste them into that field.
Printer template (optional)About templates and slicer setup
Save an OrcaSlicer or Bambu Studio project with your printer, nozzle, plate and filaments selected. Add it once; saved templates are remembered in this browser.
Without a template, select the printer and nozzle in the slicer. Layer height is stored on the stamp object: check Process > Objects as well as Global. After switching profiles, check the layer height against the notes. Keep the stated first-layer height and disable adaptive layers.
Fine artwork widths require a matching saved template. Open as a project to load its printer and nozzle. If you change the nozzle afterward, reset part width overrides and check the final layers. A two-filament template uses the artwork filament for a two-color stamp's logo.
