Adjusting the printing nozzle height
To ensure correct printer operation and optimise printing quality, apart from aligning the printing table, it might
be useful to adjust also the printing nozzle height.
Although this procedure has already been carried out at the factory, you may need to repeat it as the printer may
have been subjected to jolts during transportation.
To adjust the nozzle height, first unblock the hot-end unit by unscrewing the set screw on the extruder assembly
that can be found under the fans (use the 2.5 mm allen key supplied with the machine).
Figure 2-8 Hot-end assembly setscrew
With the set screw loosened the hot-end block is free to move; adjust the nozzle to a distance of 0.10mm from
the tempered glass table.
This adjustment can be achieved as described in the previous section, by placing a paper sheet folded in two
between the nozzle and the table. Rest the nozzle on the sheet and check that the distance between the
extruder nozzle and the tempered glass is correct, then tighten the setscrew again using the 2.5 mm allen key
to block the hot-end assembly again.
WARNING: If the height adjustment is not carried out correctly, printing quality could be poor or, in
the worst case, it could cause a collision between the hot-end and the printing table with damage to
the machine.
WARNING: The height adjustment procedure must be carried out with the nozzle in a clean
condition, free from plastic residues.
