¶ 1. Set the hotend temperature based on the filament you are using.
For PLA, a temperature of 220+ ℃ is great.
¶ 2. Wait for the hotend to reach the set temperature
¶ 3. Attach the spool to the back spool holder and cut the filament to a 45-degree angle
¶ 4. Insert the filament into the back PTFE tube until it reaches the extruder
¶ 5. From the printer screen in the filament tab, click on the rear spool holder to highlight the spool, and click on “Load.” When the pop-up appears, manually push the filament.
¶ 6. Repeat the extrude process until the old filament is purged out, and the new filament color is clear.
