Ordinary Manutention
Cleaning the printer
Sharebot NG does not require any special maintenance, but, like all machinery, eiciency increases
if kept clean.
Printing bed
The rst layer of the object we print is essential to the success of the press: for this reason the printing
oor must be perfectly smooth, with a uniform layer of lacquer applied. Aer many prints, lacquer
layers overlap and together with residues of printed pieces are compromising the atness of the sur-
face of the glass, creating irregularities: taking great care in moving we can wash the glass with warm
water and remove any residual impurities.
Stretcher
The cogwheel of the motor of the extruder and its cushioned pulley tend to “eat” the laments. For a
perfect sliding lament it is necessary to check if there’s accumulate dust or other debris by strand-
ed on the pulley and onto the sprocket. If you want to carry out thorough cleaning, unscrew the 4 lat-
eral screws (those with springs) and sweep away plaque with its bearing; then removing any residue.
Aer that you can reinstall everything and run the lament.
Nozzle
If you want to remove material le on the tip of the nozzle, prepare menu choose “Preheat” le or
right depending on the nozzle you want cleaned; then select “move axis”, and then extrude any inch
of material from the nozzle until it drags the leover material earlier. Now select “cools” and when
the temperature of the nozzle will be between 100-150° head with tweezers to pick up the dribble
of material that hangs from the extruder and pull it o. Alternatively you can select from the menu
“Prepare” the exchange command wire to the extruder interested.
Lubrication
It is required only aer an intensive use of the machine (or early if used in a dusty environment - strongly
discouraged! -). In any case it is the machine itself to ask this question began to whistle during handling.
Apply a drop of sewing machine oil or a petroleum jelly on top of worm Z and X and Y guides; handled
axes to apply uniform oil on total length.
Putting in tension the belts
For perfect eiciency of the machine, the belts that move the axes should always be properly coil; to
