Preheat hot end using front display, select the appropriate filament temperature.
Insert PTFE tube into filament feed on HS3 right panel near upper rear corner.
Open HS3 lid to access printhead filament elbow, lift out of bearing holder and set aside.
Disconnect PTFE tube from filament cartridge if connected. Feed filament through PTFE tubing by hand until filament appears at the end of the elbow.
Reconnect PTFE tube to filament cartridge.
Fully insert filament into printhead until the end of travel.
If you are loading a different material than previously printed, follow complete these instructions before proceeding to the next step: Swapping Between Filament Types If you are loading the same type of material or this is a brand new Hotend proceed to the next step.
When the nozzle is hot, select the load filament macro on the display. The printhead should now pull filament into the extruder. If you do not see any filament movement, manually feed the filament until you feel the extruder rollers grip.
Check to see material has been extruded at the nozzle. If no material is seen reselect the load filament macro again. Remove any extruded material and clean the nozzle. Persistent oozing is normal.
Reinsert the filament elbow. The printhead is now loaded and ready to print. Cooldown the printhead if you are not starting a print immediately.
Note
Avoid leaving the nozzle preheated for long durations as it burns the filament inside which may lead to clogs.
