Machine maintenance and operation
153
PTFE tube change
• wrench 10
• adjustable
wrench 150
• Wood screw or
drywall screw
Every 750 wor-
king hours
or
after 4kg of
material
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.
Replace the old PTFE tube with a standard
2/4 mm. 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.
16.5 X,Y,Z axes procedures
To Do
Tools
Frequency Solution
Checking the fric-
tion on the X and
Y axis carriages
--
Every 400
working
hours
This is done while the machine is swit-
ched off
. Manually move the toolhead left/
right and the worktable move forwards/
backwards to determine if something is
hindering their movement.
Cleaning the X and
Z axis rails from
dirt and lubricating
them
• lubricating oil
• PTFE grease
• dry cloth
• paper towel
Every 2500
working hours
This is done while the machine is swit-
ched off
. Apply some grease to a dry cloth
or paper towel and spread it on the X and
Z-axis rods. For easier access to the Z-axis
guides, the side covers can be removed.
Check the rods for dirt, remove it with a dry
cloth or mechanically. Manually move the
toolhead left/right to spread the grease.
Cleaning the Y axis
rails from dirt and
lubricating them
• lubricating oil
• PTFE grease
• dry cloth
• paper towel
Every 1500
working hours
This is done while the machine is swit-
ched off
. Apply some grease to a dry cloth
or paper towel and spread it on Y-axis rails.
Manually move the worktable forwards/
backwards to spread the grease.
Checking the ten-
sion of the timing
belts of the X and
Y axis
• adjustable
wrench 150
• Allen key 2,5
mm
Every 1500
working
hours
In the case of loose timing belts, tighten
the tension bar screws. For the X-axis belts,
evenly tighten the two screws located on
the right-hand Z-axis lift. In the case of
the Y-axis belts, first, loosen the 4 screws
securing the tension bar at the front of the
machine. Then, using a tension wrench
or simply a M4 bolt with a nut, tighten the
Y-axis straps and tighten the tension bar
screws.
