Arduino Materia 101
movement of the extruder on the plane. In
practice, you have complete control and can
perform all management and maintenance
operations. In the next chapter we will use
this menu to adjust the printing surface.
Main Menu
— Disable steppers
— Auto Home
— Preheat
— Cooldown
— Move Axis
— Change Filament
“TUNE” MENU
The item appears only when the printer
is performing a job playing the G-Code,
just by printing this article appears as first
in the list when you press the knob.
Main Menu
— Speed
— Nozzle
— Fan speed
— Flow
— Change filament
Inside there is an additional menu that
allows us to vary the overall printing speed,
expressed as a percentage and identical
to the present as a feed rate information
screen (velocity is the parameter which
is varied by rotating the knob from
the screen information). Below the set
temperature for the nozzle: the value is in
degrees Celsius and any change must be
confirmed by pressing the menu knob.
The next item is the fan speed, adjustable
from 0 to 255; with very low values the fan
may not even start to turn.
The stream value is relative to the percentage
increment or decrement in material flow
in the extrusion phase: slicing software
calculates exactly how the material is
extruded to create individual layers, but
unforeseen changes or not declared in
wire diameter than the given value as a
parameter to the slicing could then request
compensation and this entry serves for this
purpose. A value of 100 corresponds to any
variation of the flow of material, values
less than 100 reduces the contribution of
material and higher values increase the
extruded material from the value predicted
by the G-Code. In all cases, it is a percentage.
The latest rumor concerning the change of
the filament while printing: the procedure
arises from the need to replace the
filament out with a new reel for use until
after the previous coil, but this item can
also be used to change the color of the
filament or even the same type of filament
by maintaining the ability to continue
printing without defects in the object.
The procedure starts with the shift of
the extruder in parking area, then the
engine expels the current thread and the
internal buzzer is activated as soon as
the extruder is unloading. When you have
positioned the new wire on the inlet hole
and you did it so it hit the drive sprocket,
you must press the knob to start dragging
and extrusion which reloads the casting
chamber and also allows you to expel the
remnants of previous material. When the
flow of new wire is satisfactory, press the
menu knob again to resume printing.
