OrcaSlicer — import instructions

Export a filament profile

Download an OpenFilament filament JSON preset and import it with File → Import → Import Configs. Menu names follow OrcaSlicer’s English UI / wiki.

What OpenFilament exports

An OrcaSlicer filament user preset JSON (type: filament) with inherits such as Generic ASA @K2 Plus-all, plus temperatures, flow, PA, volumetric limit, cooling and retraction when known.

It does not ship printer or process presets, G-code, or RFID data.

Before you begin

• OrcaSlicer 2.0+ recommended (Beta)
• Install/select your printer profile first
• Optional backup: File → Export → Export Preset Bundle

Download from OpenFilament

1. Find filament → variant → printer/nozzle → profile.
2. Choose OrcaSlicer on the Export / Download for slicer page.
3. Create download and save the .json file.

Import into OrcaSlicer

1. Open OrcaSlicer.
2. Choose File → Import → Import Configs (wiki: Preset Configs).
3. Select the OpenFilament .json filament preset.
4. Confirm overwrite if a preset with the same name exists.

Select the imported profile

• Open the Filament dropdown.
• Locate the user preset (brand / product / colour).
• If missing: Filament settings → Dependencies — enable your printer/nozzle.

Connect it to physical filament

For an external spool, select the imported filament on the prepare tab. For AMS/CFS-style mapping in Orca, map the slot to this user filament only where your printer profile supports it — OpenFilament does not auto-write RFID.

Verify the import

• Preset listed under user filaments
• Printer and nozzle active
• Temps / flow / max volumetric match
• Project slices with this filament

Troubleshooting

• Invalid configuration — ensure JSON (not Prusa .ini).
• Hidden after import — fix compatible_printers / Dependencies.
• Wrong inherit base — re-export after choosing a closer printer model.

Remove or replace the profile

Delete the user filament preset in OrcaSlicer, or import a newer OpenFilament download. Prefer distinct revision filenames from OpenFilament.

Known limitations

• Beta support
• Filament-only export
• Inherits Generic @printer-all style bases

Track filament consumption

A slicer estimate is never presented as automatically measured actual usage. Physical actual usage requires scale measurement.

Before printing, import or enter the slicer estimate, review length, volume and weight where available, and map each tool, AMS/CFS slot or material to a physical spool.

After a successful print without printer integration, confirm completion and edit the full estimate before deducting it as completed-print estimate.

After a failed, cancelled or interrupted print, OpenFilament does not deduct the full slicer estimate automatically. Use reliable printer-reported extrusion or enter a manual correction in grams.
