Cause
• Extruder blocked.

or unloading the filament.
• Not all the filament was removed
from the hotend when replacing/
removing�
• Glitch interrupts software�
• The cover fan connector is not prop-
erly inserted�
Corrective action
• Unblock the extruder, see Chap. 10.3.
• Choose the right temperature for the filament.
• When loading or unloading the filament, wait for the ex-
truder to fully reach the temperature�
• When removing the filament, proceed as follows:
- To facilitate filament extraction, press the extrude func-
tion for 5 seconds followed immediately by the reverse
function�
- Use your fingers to slightly withdraw the end of the
filament that is sticking out of the extruder. Extrusion is
necessary, all the previously melted filament must be
melted in the hotend�
