6.4 Filament Does Not Come Out
Possible Causes
(1) The nozzle is blocked.
(2) The lament has poor quality ranging from impurities to inconsistent diameters.
(3) The lament is not supported by the 3D printer.

(5) The hot end is malfunctioning.
Solutions
(1) If the nozzle is blocked, see 5.2.4 Check the Nozzle.
(2) Replace it with a quality lament.
