7.
The extruder motor will start after activation of the sensor. Push the filament so that its tip passes through the entire
length of the bowden tube (fig. 38, point 3) up to the extruder (fig. 38, point 4). If the material has been inserted correctly,
it will be intercepted by the extruder. The material will be drawn by the extruder and resistance will be felt when
attempting to withdraw the material.
8.
When the nominal material extrusion temperature is reached, the process will start automatically. The extruder will push
the material through the short bowden tube (fig. 38, point 5) to the hotend heated up to the material plasticization
temperature.
9.
Observe the nozzle tip carefully. The printer will perform a test-extrusion of a short section of the filament.
10.
Confirm successful loading of material with "
CONTINUE"
key and remove the remaining extruded material from the
heatbed.

4.2. Material unloading
1.
From the "
MATERIALS"
level, choose the
"UNLOAD MODEL MATERIAL"
option located under TOOL 0 extruder or "
UNLOAD
SUPPORT MATERIAL"
option located under TOOL 1 extruder. The filament unloading assistant will start in order to display
the sequence of commands and guide the user through the next steps of the process.
2.
Cut the material about 5 cm in front of the input opening of the filament sensor and remove the spool from the holder.
Remember to keep the filament in a dry place protected against direct sunlight.
3.
When the correct temperature is reached, the material unloading process will start automatically. Initially, the extrusion
of the material will be performed in order to facilitate its subsequent withdrawal.
4.
Slide the remaining filament out of the bowden tube and confirm that the assistant has finished its operation. To facilitate
the removal of, for example, remains of material extended at their ends, the extruder motor will run until the material is
completely removed from the bowden tube.
