WARRANTY
• Equipment manufactured by Noztek carries the standard machine tool guarantee
of freedom from defects in workmanship and material for one year from date of
shipment.
• TO INSURE THAT YOUR WARRANTY IS HELD IN EFFECT, PROPER OPERATION PROCE-
DURES MUST E O SERVED.
• NOTE: READ THE SAFETY PRECAUTIONS EFORE OPERATING THIS MACHINE.
SAFETY
1. Know your equipment
2. Carefully read the instruction manual.
3. Learn the use and limitations of the equipment.
• DO NOT operate or use this equipment for any purpose other than its intended
use.
• DO NOT modify this equipment.
• DO NOT perform adjustments or maintenance while system is operating or ener-
gize
• Do not clean the equipment with flammable solvents.
• Do not wash down the equipment with water. This could cause an electrical hazard.
• Do not probe into extruder vent with the machine running. Never Use a metal
probe in the vent area. The screw may shear the probe, causing extensive damage
to the barrel and screw. A wooden probe is recommended.
• A face shield, insulated gloves, etc. should be worn around the extruder during op-
eration. They must be worn when adjusting the die, cleaning the screw, etc. The
extruder temperatures are extremely hot.
• The feed hopper must be installed on the extruder feed section at all times when in
operation
• Never put hands in the feed section or vent to remove material.
• Do not switch on the motor until the recommended temperature has been reached

MAIN FEATURES
4.3-inch Touch screen: HMI Capacitive Touch Display.
Timer: enables you to shutdown the running session by deactivating the heater bands and motor.
Last targets memory: the last target temperature and speed will be remembered after a restart. Last
timer settings will also be kept.
PID: The Noztek Touch is using PID for temperature and speed control.
Warm-Up: It's designed to allow the barrel to fully heat after 10 minutes so un-melted materials do
not block the motor and avoid damaging it or the machine.
Emergency shutdown: To electrically shutdown the extruder.
Motor blocking management: If the motor cannot run for any reason a message will be prompted
and the motor stopped.
Sensor malfunction detection: If the temperature readings are incorrect a message will be prompt-
ed.

QUICK START GUIDE
Turn on machine using illuminating on/off button.
Once powered up, the Touch will take a short period to boot into the main screen. From here, you can
control the motor and the two heater bands. TEMP 1 represents the main heater band. TEMP 2 rep-
resents the pre-heater band.
RACKET
If you are using the 45 degree bracket it is very important that the extruder is se-
cured to a workbench using the mounting holes in the bottom of the bracket.

OPERATION GUIDE
·Remove the unit from the packaging
·If you are using the 45 degree bracket, secure the extruder to a bench using
the mounting holes.
·Plug the extruder into mains power.
·Switch on the heater element and adjust the temperature gauge to the de-
sired setting. For A S we recommend between 180 – 200 degrees Celsius and PLA
between 165 -175c. To adjust the heat setting press the set key once, the tempera-
ture 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 recommend-
ed 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 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 high-
er 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.

USER INTERFACE
Main Screen
This screen shows the current temperature of the individual heating bands and the speed of the mo-
tor (top row), their set temperature and speed (second row), activation/status switches (third row),
and access to the Menu screen (bottom).
To activate the heating bands, touch any of the temperature activation/status switches. Upon activat-
ing the heating bands, the Xcalibur display will switch to the “warm up” screen (fig.3). The Xcalibur
will not exit this screen until the heating bands are at set temperature, or the user aborts the heating
process. The motor switch will activate the warmup to allow the motor to run safely after it.
Warmup Screen
This screen is displa ed when ou heat for the first time or when the temperature dropped under
the target. This warm up is to ensure that the barrel has reached a certain temperature before being
able to run the motor safel .

Menu Screen
The menu screen (fig.4) gives the user access to all of the Xcalibur's settings and additional function-
ality.
Fig.4: The menu screen options.
SET TEMP: sets the desired temperature of the individual heating bands.
SET SPEED: sets the desired revolutions per minute (rpm) for the D.C. motor drive.
FAN: ON/OFF: activates or deactivates the fan.
TIME LEFT: sets a timer for automatically shutting down the DC motor drive and heating bands.

CHANGING THE NOZZLE
efore 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, then screw on new nozzle.
COLOUR MIXING
Adding colours is simple. Mix the natural and the colorant at the given ratio, then
pour it into the hopper. It will take 10-20 minutes to see changes in the colour. It is
also possible to mix colorants to create new colours. For example, mix blue and yel-
low make green.
MAINTENTANCE
Regular cleaning of your plastic extrusion tooling during the disassembly process
lengthens tooling life, helps reduce waste and helps maintain tighter tolerances for
your final product. Use a wire brush and fine metal pick to clean the threads and the
screw assembly
LU RICATION
The thrust bearing assembly will require occasional lubrication; this is a relatively
simple operation, simply unscrew the brass grease nipple and squirt a 2 second
burst of a lubricant like WD40 Lithium Grease. For optimal performance we recom-
mend this procedure is carried out every 100 hours of operation.
ARREL JAM
Depending on what type of resin you are using, you may experience a barrel jam. If
at any time during extrusion the motor starts to labour and slow right down then you
should switch off the motor immediately. A good way to free the jam is to turn the
temperature up to say 230-240c and leave this for 15 – 20 minutes, then switch on
the motor again; this should allow the screw to rotate again. Also using a blow torch
to heat the barrel just past the hopper will usually release any solidified plastic and
free the screw.
