Printing plate
The first layer of the object that we print is crucial for the success of printing: for this reason the printing surface must be perfectly smooth, with a uniform layer of
hairspray applied. After many prints, layers of hairspray overlap each other and together with the residues of the printed parts compromising the flatness of the surface of
the printing glass by creating irregularities: paying attention you can wash the printing glass with warm water and remove any remaining impurities.
Regulation of pressure upon filament
The cogwheel of the motor of the extruder and the relative amortized pulley tend to "eat" the filaments. For a perfect dragging of the filament you should check that no
out dust or other residues of filament remains between the pulley and the cogwheel. If you want an accurate cleaning, unscrew the 4 lateral screws (the ones with the
springs) and remove the plaque with the corresponding bearing; then proceed by removing any residue. After that you can mount the whole things and launch a “change
filament” procedure.
During the dragging of the wire try to block it with your fingers: if this cause a “skidding” of the cogwheel on the filament”, the springs must be tightened up to cause a
loss of steps to the engine (you should hear a ping-like tak tak). The springs should not be too tight to avoid that the engine is under too much stress and consequently
loses steps.
Nozzle
If you want to remove the material left on the tip of the nozzle, select "preheat" from the "prepare" menu; then select "move axes" and extrude some inches of material from
the nozzle, until it sweeps away the material retained previously. Now select "cooldown" and when the nozzle temperature will be between 100 ° and 115 ° go with
tweezers to take the melted plastic that hangs from the extruder and detach it. Alternatively you can select from the "Prepare" menu the "Change Filament" command.
Lubrication
Is only necessary following heavy use of the machine (or prematurely if used in a dusty environment - strongly not recommended! -). In any case is the machine itself that
ask it, starting to whistle during movement. Therefore apply a drop of oil for sewing machines (or vaseline based) on the summit of Z screw and on the X - Y guides; move
the axes to spread the oil for the entire length.
