Loading filament
One of the more common operations in our BCN3D+ will be, for several reasons, loading and unloading filament: a
change of color, a change of material, using a fresh spool, cleaning, maintenance...
The following steps must be followed:
1. Heat the extruder. Warm the hotend up to printing temperature.
It is not necessary to click on Preheat, although it is advisable when wanting to print immediately after loading the
spool. If that is not the case, click
Menú>Control>Temperatura>Nozzle>220ºC .
2. Click on Prepare>Move axis> 1mm>Extruder , and rotate the wheel slightly clockwise (positive values) to extrude
a few millimeters of material. This procedure will help prevent jams.
3. Click on Prepare>Move axis> 1mm>Extruder , and rotate the wheel anticlockwise (negative values) moving the
gear a few steps back until the filament is free.
4. Once the old thread is out, load the new one. Click on Prepare>Move axis> 1mm>Extruder so the screws hold it
tight . Move the wire slowly until the material exits trough the end of the hotend.
5. For a proper filament feeding, the idler screws must be tightened enough, offering a slight resistance when
assisted with our fingers.
6. Once the extruder starts pulling the filament, tighten the screws until enough pressure is reached.
7. Once these steps are followed, the filament will be loaded and ready to print.
