Arduino Materia 101

calIBRaTION

Take a look at the power supply’s

wiring. If it is OK, turn it on! Now we

can look at a couple of things. If you

do not see “MATERIA 101” on your

LCD panel, you need to upload the

firmware onto your 3D printer. You

can download it here: http://arduino.

When the printer is on, the white

LEDs are also on. Take the multimeter

and set it on the DC reading; place

the black tip on the negative input

(black). Place the red tip on the

stepper motor’s driver potentiometer.

Potentiometers are the small star-

shaped screws that you find on

the driver. To check the stepper

driver Vref, adjust the Vref with the

following values: X0.4 Y0.4 Z0.4 E0.5

and adjust the potentiometers with

a small screwdriver. Be certain not to

touch anything else conductive when

adjusting the potentiometers and use

a ceramic screwdriver.

On the display you will read “Materia

101” and a thermistor temperature

next to the ambient one.

From the LCD menu select Prepare

-->Autohome : you see that X, Y e Z

motors will read every end-stop (X to

the right, Y to the bottom, Z goes up).

When the autohome has been

triggered, the back extruder motor

fan must turn on.
