11. Final Work
If the motors are moved manually, the display may light up. This is not a malfunction. A voltage induced by the movement
causes the display to light up.
Connection of the earthing plate
Place the heating plate onto the spacer bolts of the undertable
and connect the two plug connectors from line 12 and 20.
Basic setting limit switch Z-direction
Loosen the actuation screw in the Y-plate for the limit switch in
the Z-direction and turn it all the way into the hexagon bolt.
Carefully turn the toothed belt of the bottom plate until there is
a gap of 0.5 mm (+/-0.2 mm) set between the heating plate and
extruder. 0.5 mm correspond roughly to the thickness of 5 lay-
ers of printer paper (80 g/m²).
Caution: No force must be applied to the heating plates, since
the ceramics material would break otherwise (loss of war-
ranty/guarantee).
Set the adjustment screw so that the limit switch of the Z-di-
rection is tripped in this position (a slight click is audible).
Move the extruder and Y-plate manually and ensure that the
extruder cannot touch the heating plate anywhere in the work-
ing area and that the same distance is complied with every-
where.
If this is not the case, the undertable plate must be aligned
carefully. However, the heating plate must be taken off first
(danger of breaking!).
After this setting, counter the setting screw with the nut
again.
