Recommended filaments: PLA and PETG.
When purchasing filament, choose reputable brands with a proven track record. Consistent filament diameter, high material purity, consistent batch quality, and moisture-resistant packaging can significantly reduce nozzle clogs, stringing, and color inconsistencies, improving print success rates.
Tip: For the best printing results, we recommend loading the i8 with four spools of the same filament type that use the same printing temperature. For more filament types and details, please refer to the i8 Filament Compatibility Guide.
Note: Before printing, make sure loading is complete for every filament channel you plan to use. To load multiple spools, use One-Tap Load.

5. If the filament gets stuck at the pneumatic connector during insertion, the PTFE tube may not be properly seated. Reinsert the PTFE tube and push it all the way in until it cannot go any further before feeding the filament again.

¶ Error
951303If either code appears during printing, retry filament loading as follows:
- Tap Retry on the printer screen.
- Gently push the filament forward until it engages the extruder drive gears.
- If the filament does not advance, pull it back out, reinsert it, and try feeding it again.

- A solid white light indicates that the filament has been inserted. A breathing white light indicates that the corresponding channel is selected.
- It is normal that the filament cannot be retracted: when the feeding channel is selected (closed), the feed gear and extruder gear clamp the filament together, so filament retraction cannot be performed at this time.
