FILAMENT DETECTION/MOVEMENT SENSOR
Using PLA and PET+ profiles, the filament sensor is active by default and if you want to
switch it off you can from the display menu during the printing process.
NOTE: The sensor is deactivated each time the printer is switched on. Using the supplied
print profiles the sensor is automatically activated at the beginning of the printing process.
With TPUre  profile, on the other hand, the filament sensor is deactivated. This allow to
place the spool on an external spool holder, to facilitate the unspooling process of this
elastic material.
Ideal spool positioning:
The spool should be placed inside the printer on its support;
Otherwise it can be placed externally (as is often done with the TPUre  , placing it on top of
the printer to facilitate unspooling);
Cases of automatic filament change during printing process:
● The filament is finished;
● Filament grinded;
● Filament knot on the spool;
● Poor extrusion;
● No extrusion;
In all this cases, the printer performs the same procedure of “changing filament”, also
selectable when the printer is idle. Machine goes to the filament change position, expel the
residual filament, and wait for the user to replace it:
1. Read on the display which extruder has entered in the change filament procedure
2. Release the quick coupling of the guide, remove the remaining filament by
unlocking the dragger gear using the specific lever;
3. Insert the new filament spool and push the tip of the new filament making it run
along the entire guide until it comes out for some centimeter;
4. Insert the new filament till the hot-end, lock the dragger gear using the specific lever
and then click OK on the screen button for confirmation;
5. Check the extrusion from the nozzle and give the last click that closes the
procedure.
6. The printing is resumed from where it was suspended.
Safety cooling down
Passed five minutes after the filament change procedure is started, without the new
filament has been loaded, the extruders temperature is switched off, to prevent extruders
from clogging.
In this case the first click of the procedure will heating up the extruders; when the
