Filaments and plates the target drops

A target slicer sometimes holds fewer filament slots or plates than your file uses. Converting a file never drops one quietly: you choose which survive, or the choice is made the same way every time, and either way the Notes table names what was left out.

When the target keeps fewer filaments

Cura gives each filament its own extruder, so a Cura printer with one extruder keeps one filament. An eight-colour Bambu Studio file cannot bring all eight. preslice never picks for you: choose Cura and the Change filament row turns on by itself and cannot be turned off while the choice is open.

Ultimaker Cura keeps 1 of 8 filaments. Pick 1 to keep.

Click a source filament to keep it. The others then read dropped, and clicking one of them swaps it in. If you press Convert before choosing, the conversion asks the same question and converts nothing until you answer. The choice is saved with the conversion, so reopening the file shows the slots you kept, and keeping a different one offers Revert and convert.

PrusaSlicer, Bambu Studio, OrcaSlicer and Creality Print keep every filament, even on a one-extruder printer, so they never ask.

After the conversion, the Notes table holds one row per filament that did not make it, each naming its colour: Filament 2 · Bambu Lab PETG #7C4B00 · dropped · Ultimaker Cura keeps 1 filament.

How many plates carry

Target How many plates carry
Bambu Studio, OrcaSlicer, Creality Print every plate
PrusaSlicer up to 9, one per bed
Ultimaker Cura one, the one you pick

PrusaSlicer 2.9 holds up to 9 beds (MAX_NUMBER_OF_BEDS = 9). A tenth plate and beyond convert to nothing, and the Notes table names them:

Plate 10 · dropped · PrusaSlicer holds 9 beds

Cura keeps one plate. Its row sits under Change bed, and it shows for a Cura target only: pick which plate survives the same way you pick which filament survives, above. The rest drop, named the same way.

A PrusaSlicer 2.9 file with several beds reads the same way it writes: each bed is its own plate. Converting one to Bambu Studio, OrcaSlicer or Creality Print writes one plate per bed.

Per-plate settings that do not carry

Neither PrusaSlicer nor Cura has a place for a plate's own settings. A plate's bed_type or print_sequence has nowhere to go on either target, so the Notes table names it instead of dropping it without a trace:

Plate 2 (Plate B) bed_type · textured_plate · not carried · The target has no per-plate settings
