[Arco] Filament Replacement Guideline

After printing is complete and the filament runs out, how can you replace it correctly to minimize jamming and prevent damage to your printer? Here are several recommended methods for Arco:

Method 1: Replace Filament After Retraction (Recommended)

If possible, use this proactive method:

1. On the extruder control interface, heat the filament to 250°C. 
   
2. Click the Retract button and wait until the filament is fully released from the extruder gear.
3. Manually rewind the filament from the spool and store it in a dehumidifying device. 
    
   

Method 2: Replace Filament Using Cutter

If using a cutter:

1. Press the cutter lever and confirm through the observation window that the filament is cut. 
   
2. Manually rewind the filament from the spool and store it in a dehumidifying device. 
    

⚠ Note: This method leaves a filament residue inside the extruder (from the cutter to the hotend). Follow these steps:

• Insert the new filament into the PTFE tube until you feel resistance inside the extruder.
• On the extruder control interface, heat to 250°C and click the Load button.
• Manually assist by pushing the filament and click Extrude 1–2 times until the hotend extrudes the new filament. 
  

Method 3: When Filament Runs Out Naturally

Due to Arco’s design, there will be leftover filament between the extruder gear and the hotend. Follow the second half of Method 2:

• Insert the new filament into the PTFE tube until you feel resistance inside the extruder.
• On the extruder control interface, heat to 250°C and click the Load button.
• Manually push the filament and click Extrude 1–2 times until the hotend extrudes the new filament.

Important

If you feel strong resistance during pushing and the filament cannot extrude smoothly, your extruder may be jammed. Please refer to our Help Center for the “Extruder Jam Troubleshooting Guide.”
