User manual
When the nozzle is heated up to a temperature, lament 
feeding motor will be activated. The motor is operated via 
front two buttons [Pic. 16]. Button closer to the nozzle feeds 
the lament forward, the other button pulls out the lament 
after one click. If the buttons work the other way, the motor 
is plugged the wrong way and you have to unplug the 
motor, turn around the connector and plug again.
