BEFORE THE FIRST PRINT:

sewing machine oil. Spray hair spray
on the glass printing bed.

It is time to fix the springs on
the extruder. Choose the option
”Change filament” from the printer’s
menu. Wait until the machine has
finished the expulsion cycle. Then
you can insert the filament. While
loading, try to block the wire with
your fingers. If this should cause a
skid of the pulley on the filament
you have to tighten the spring until
the motor should lose steps (you
should hear a noise like a “tak tak
tak”). Be careful not to tighten the
springs too much: this will cause a
loss of steps to the motors and grind
the filament.
