8. Bring the nozzles to the zero point using the Auto Home procedures in the menu as described in
Figure 4-16 Command Sequence for Auto Home and Disable Motors
WARNING: to avoid reverse currents produced by the motors damaging the electronic parts, move
the extruders very gently and using small limited movements.
NOTE: The Bed Setting function automatically moves the hot-end group to the 5 points necessary for
regulating.
Perform the adjustment as shown in the video clip
9.
If the height adjustment is not carried out correctly, bad printing quality might result. In extreme cases it
could cause a collision between the hot-end and the printing plate, damaging the machine.
NOTE: the first layer printed is normally deposited with a greater thickness than the other layers (by
appropriate setting of the slicing software). This precaution can compensate for any small
misalignments.
The tempered glass does not have a planarity with centesimal resolution, therefore the first printed
layer of the material may not be deposited uniformly. It is therefore very important to ensure that the
outer lines are uniform so as to guarantee good adhesion. The centesimal differences in height are
compensated for in the 2-3 successive layers.
