Sharebot Next Generation XXL+
user's manual
“Nozzle” is to set the temperature of the nozzle: the value is in degrees Celsius and any change must be confirmed by pressing the menu knob. Same thing for following
item, the heated bed.
“Flow” is relative to the percentage increment or decrement of the extrusion phase: the slicing software calculates exactly how the material is extruded to create
individual layers, but with this item we can "get fat" or "lean" the print as we prefer.
The last item is about the printing speed: we can change the percentage of all the speeds of the gcode. It is identical to the one that we can change directly in the info
screen. Note that generally, increasing the speed, decreases the quality.

Setting the printer
Your Sharebot XXL+ is a mechanical device built with care both in design and in the assembly from qualified staff in Italy. To keep it in a state of optimal
functioning is necessary to compensate some normal processes of adjustment, for example, due to repeated thermal cycles of extruder motors and print
heated bed.
During each printing process, the entire machine is subject to vibrations and movements that in the long run can loosen the four screws that hold the
printing bed. This leads to not have more precise and uniform spacing of the glass plate from the extruder which inevitably fails to apply the first layer with
the accuracy and uniformity necessary for quality printing. Just exit out of the box, Sharebot XXL+ should be even with the exact factory calibration, but a long
journey or vibrations during transport may have done move some calibration screw.
Loading the filament
The first thing to do before printing is load the printing filament. Sharebot XXL+ has a specific procedure to load the filament from “Prepare” menu: select “change
filament” and the procedure starts heating the extruder; when the temperature of 230° c is reached, you can load or unload the filament (the procedure is identical to that
which is accessible from the menu “Tune” described in the previous chapter).
When the extruder is cold it retains the material: don't force it by pulling or pushing it into the extruder. To load the filament, obliquely cut the filament tip and insert it in
the PTFE guide through the check filament sensor till the extruder head, making sure that the filament is dragged, surpassing the cogwheel and into the hole below. You
can help yourself by releasing the teflon guide pressing the orange quick-release on the extruder block.
