User Manual
Arduino Materia 101
If you have followed the instructions
in this manual, you have already set up
your Arduino Materia 101 by placing it
on a table with the spool holder, you
connected the power supply, turned on
the printer, calibrated the printing bed and
you have also uploaded the plot strand.
Now you can proceed to your first print.
the sd card
In the box you will find the plastic container
with your SD memory card. On this card
you can put G-code files (see Chapter 2)
that you want to print. Preloaded at the
factory are some sample files that are ready
for printing so you can make your first print
knowing that the file has been prepared with
optimal parameters to get the best result.
Printing PrOfiles
Theoretically, every G-code requires a
specific material that is determined by the
values set by the temperature of the nozzle,
heated bed temperature and fan speeds. To
print the same object in different materials,
one should then create separate files.
To work around this limitation, the Arduino
Materia 101 allows you to select, before
printing, the outline of the material that
you use. In this way, you can create a
generic G-code to be printed with the
chosen material simply by choosing the
corresponding profile. In other words, you do
not need to insert the various temperature
parameters and fan speeds in the slicing
program because they are set correctly when
you choose the desired material profile.
starting the Print
Press the knob again to enter the menu,
then choose “SD card menu”. Choose
which printing profile you want to use:
choosing “use set g-code parameter””
will print the object with the values
set in the slicing software; choosing
the PLA will print profile with standard
parameters of PLA and similar (extruder
temperature: 220°, 255 or full fan speed).
Once you have selected the profile, the SD
card’s contents are displayed like files and
folders. By turning the knob, you can scroll
down to the file you want. By pressing the
knob you make your selection and start the
print. Your Arduino Materia 101 will begin the
heating procedure and positioning itself at
the home position of the axes, then when it
reaches the correct temperature it will start
with the first layer. Check that the filament
is sticking to the printing surface without
being too flat or only resting like a round
string on the surface. If you have successfully
run the calibration G-code, you will have no
problems. If you have trouble, you should
stop printing and redo the calibration (Fig. 1).
stOPPing the Print
While printing you can pause or
abort printing. The two options are
available directly from the main
menu as “pause” and “stop print”.
It may take a few seconds for the printer
to stop after “pause” is pressed.
In the second case, the printing
stops immediately and for good.
The extruder then goes to the X and
Y home coordinates position.
Unfortunately, the point on the object where
the extruder stops can be affected by heat
and might deform. A runny drop of material
from the extruder could also form where
the extruder stops. So the pause function
should only be used for short periods of time.
Try and pause it only when the extruder
is tracing the infill so that the drop or
deformation is hidden inside of the object.
mOdifying Printing
Parameters
One of the features of Arduino Materia
101 is the ability to tune a number of
parameters while a print is running.
The “Tune” menu will become available
instead of the “Prepare” (see Chapter 3).
This allows you to adapt the selected
PLA profile or the set G-code values to a
different material with other behaviors
and characteristics (Materials table in
Chapter 7), change the temperature of the
nozzle and print bed, and the fan speed.
Changing the feed rate, you can slow down
or speed up the overall printing speed to
handle any problem, that a certain material
or model might have. It might be that
