Solution
Cleaning the
nozzle surface
from dirt and
material residues
▪
tweezers
▪
wire brush
Before
each job
Remove any residual material from the
heated nozzle with tweezers. If the leftover
material cannot be removed with tweezers,
a wire brush can also be used.
Nozzle (interior)
cleaning
▪ drill 0.3mm or
0.4mm
After each
material
spool
After using the whole spool of material, burnt
material may begin to settle on the internal walls
of the nozzle. To avoid clogging clean the nozzle
with a drill pushing it inside the nozzle from
below in a few moves. Then, pass through the
nozzle a few centimeters of material.
Nozzle change
▪ wrench 10
▪
adjustable
wrench 150
The nozzle must be warmed up to 200°C, after
heating it up, switch off the machine and remove
the toolhead from the X carriage. The adjustable
wrench must be placed on the heating block
just above the thermistor (heat sensor) and
tightened, with the use of a flat wrench (10)
unscrew the nozzle from the heating block taking
care not to damage the heating barrier.
PTFE tube change
▪ wrench 10
▪
adjustable
wrench 150
▪
Wood screw
or drywall
screw
Every 750
working
hours or
after 4kg of
material
The nozzle must be warmed up to 200°C, after
heating it up, switch off the machine and remove
the toolhead from the X carriage. The adjustable
wrench must be placed on the heating block
just above the thermistor (heat sensor) and
tightened, with the use of a flat wrench (10)
unscrew the nozzle from the heating block taking
care not to damage the heating barrier. Remove
the old PTFE tube using the Wood screw by
screwing it into the tube. Replace the old PTFE
tube with a new (2/4mm) one. You can use the
old tube to cut a new one at the same length.
The new tube must be the same length (0.1 mm
longer than the thermal barrier is acceptable),
otherwise the material might leak out of the
heating block.
