Arduino Materia 101
PUTTING IN TENSION THE
EXTRUDER’S RUBBER BANDS
Your Arduino Materia 101 is equipped with
a cushioned versus pulley sprocket wire
drag. This solution allows to compensate for
thickness variations that some filaments can
have, allowing you to bring the press anyway.
The correct tension of the compensating
Springs allows optimum filament drive
Select the display “Prepare” menu the option
“Change filament”. Wait until the machine
ejector cycle terms and once finished, insert
the wire. While loading try to lock the thread
with your fingers; If this were to lead to a
“slip” of the sprocket on the filament, tighten
the springs until you have an outlet to blow
away the engine (you should hear a ping like
a tak tak).
Similarly, the springs must not be too
narrow to protect the motor is too under
stress and consequently lose steps.
