Install motor
1x actuator
4x cylinder head screw M3x12
Attach the actuator to the X-plate with the 4 screws as shown
in the figure.
Apply screws with threadlocker varnish.
The cable exit of the actuator must point at the rear of the plate
as shown.
Attach toothed belt
1x toothed belt 675 mm
Caution:
The toothed belt must not be tensioned too strongly. If the belt
tensioner bends, the belt tension must be reduced under all
circumstances.
A method for more precise setting of the belt tension is found
in the chapter „Maintenance“.
Relieve belt tensioners entirely.
Insert the toothed belt on the motor pinion and then into the
belt holders as shown in the first figure.
Then put the toothed belt across the belt tensioner.
Caution: For the above steps, always observe that the guide
carriage does not leave the guide rail.
Tension toothed belt by turning the belt tensioner screw until it
can still easily be turned by 180° with two fingers.
After the belt has been installed, move the extruder carriage to
check whether the limit switch (arrow in the right of the figure)
is tripped by slight pressure from the end stop actuation (trig
-
gering leads to a slight click).
If the limit switch is not actuated, loosen the screw again (ar-
row to the left on the screen) and twist the holding plate for the
end stop actuation a little until the limit switch can be actu-
ated.
