Extrusion Operation; Changing The Nozzle - Noztek Pro User Manual

In an emergency simply hit the button and the Noztek Pro will completely switch
off. To restart, simply untwist the button.

Extrusion operation

• Remove the unit from the packaging
• If you are using the 45 degree bracket, secure the extruder to a bench
using the mounting holes.
• Make sure you are in a well ventilated area
• Plug the extruder into the mains.
• Switch on the heater element and adjust the temperature gauge to the
desired setting. For ABS we recommend between 180 – 200 degrees
Celsius and PLA between 165 -175c. To adjust the heat setting press the
set key once, the temperature led will then flash, then the click up or down
key to adjust. When you reach the desire temperature click the set button
to engage. Let the extruder barrel heat fully this should take about 15
minutes.
• Once the required temperature has been reached, fill the hopper with
resin pellets.
• Switch on the screw motor (Do not switch on the motor until the
recommended temperature has been reached).
• Switch on the fan
• After a few minutes you will see plastic filament starting to extrude,
carefully feed this through the guide, This filament will be hot so use heat
resistant gloves
• Extrude approximately 5m of filament, switch off the motor, cut off the
excess material, and then restart the motor. This should help to eliminate
any air bubbles and metal particles in the system.
• Adjusting the temperature also affects the tolerance of the filament. The
higher the temperature, the thinner the filament. The lower the
temperature, the thicker the filament.
• Make these adjustments in 5 degree Celsius increments.
• If the extruder is left unattended for any period of time we recommend
using a mains timer switch.

Changing the nozzle

Before attempting this operation please use insulated gloves.
To switch between nozzle sizes to heat up the unit to175c, unscrew the nozzle,
clean off any excess plastic from the internal threads, and then screw on new
nozzle.
