To Do
Tools
Frequency Solution
Cleaning the
nozzle surface
from dirt and ma-
terial 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 clog-
ging 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

• adjustable
wrench 150
--
The nozzle must be warmed up to 200°C,
after heating it up, switch off the machi-
ne 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.
