¶ 1. Choose Filament
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.
¶ 2. Load Filament
Note: Before printing, make sure loading is complete for every filament channel you plan to use. To load multiple spools, use One-Tap Load.
¶ 2.1 Insert the filament
- Trim the filament tip so that it is cleanly cut and free of bends.
- Check the channel numbers on the spool holder.
- Place each spool on the corresponding holder, with the filament feeding in the direction shown.
- Insert the filament into the corresponding PTFE tube and feed it through to the toolhead inlet. Once the indicator for that channel lights up, continue pushing gently until the filament stops advancing.

¶ 2.2 Set the Filament Information
- On the Filament page, tap the spool icon for the channel, then tap Edit.
- Set the brand, material type, and color to match the filament you have installed, then tap OK to save. Complete this step before starting the loading procedure.

¶ 2.3 Load Multiple Spools (Recommended)
- Insert the filament and set the filament information for each channel you want to load, as described above.
- On the Spool Holder page, open the load/unload menu in the upper-right corner and select One-Tap Load.
- When prompted, check that the filament in each relevant channel has been gently pushed in as far as it will go, then tap Done.
- Wait for the loading sequence to finish. A line connecting a spool icon to the toolhead icon indicates that loading is complete for that channel.

¶ 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.
¶ 2.4 Load a Single Spool
- Insert the filament and set its information, as described above.
- Tap the spool icon for the channel you want to load, then select Load.
- When prompted, check that the filament has been gently pushed in as far as it will go, then tap Done.
- Wait for the loading sequence to finish. A line connecting the spool icon to the toolhead icon indicates that loading is complete.

- 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.
¶ 3. Unload Filament
¶ 3.1 Unload Multiple Spools
- On the Spool Holder page, open the load/unload menu in the upper-right corner and select One-Tap Unload.
- Wait for the unloading sequence to finish. The line between each affected spool icon and the toolhead icon disappears when unloading is complete for that channel.
- Pull the filament out of the PTFE tubes, rewind it onto the spools, and remove the spools.

¶ 3.2 Unload a Single Spool
- Tap the spool icon for the channel you want to unload, then select Unload.
- Wait for the unloading sequence to finish. The line between that spool icon and the toolhead icon disappears when unloading is complete.
- Pull the filament out of the PTFE tube, rewind it onto the spool, and remove the spool.

¶ 3.3 Quick Unload
- Release the motors. Open Control and tap the motor release button.
- Cut the filament. Slowly move the toolhead along the X-axis to the far left until the component outlined in red extends. This cuts the filament in all four channels at once.
- Reset the cutter. Slowly move the toolhead to the far right until the component retracts.
- Remove the filament. Pull the filament out of each channel in turn and rewind it onto its spool.
- If filament in a channel cannot be removed, go to Home > Control, switch to another channel position, and try again.
