Set-up Instructions

Unpacking and Placement:
Caution: Do not plug the machine into the mains or turn it on during set-up. Carefully unpack the machine and accessories. Place the machine on an even, stable surface, ensuring there are no flammable materials nearby as the heater bands can reach temperatures of up to 600°C.
Hopper Attachment:
Begin by attaching the hopper. Locate two bolts in the barrel’s designated holes. Unscrew these bolts, position the hopper over the holes, and securely screw the bolts back in place.
Optional 45-Degree Angle Setup:
The extruder can be used flat on an even surface or at a 45-degree angle using the provided mounting brackets. Secure the brackets with the six bolts provided: two for each end and two connecting the brackets. Note: When in the angled position, ensure the machine is properly secured to prevent accidental tipping.
Power Connection:
Once the initial steps are completed, you can plug the main cable into the machine. Before doing so, double-check that the mains voltage (e.g., 220VAC or 110VAC) matches the voltage specified on the machine (refer to the sticker on the machine).
Note: Always follow these set-up instructions meticulously to ensure the safe and effective operation of the machine. If you encounter any issues or have questions, refer to the comprehensive user manual for further guidance.
(Optional) USB Connection:
To utilize this machine with our Noztek controller software, use the provided A-B USB cable. Connect the cable from the back of the machine to your computer. Please note that the controller software is compatible only with Windows machines.

Operation Instructions

Important Note:

Ensure that you acquaint yourself with the proper handling guidelines for the material you are using, particularly its melting point. Neglecting to do so may compromise the functionality and potentially damage the equipment.
Please bear in mind that the quality of the extruded filament is influenced by factors beyond just the operation of the machine. Considerations such as room humidity, temperature, material humidity, and ensuring the correct temperature settings all play crucial roles.

STEP 1. Familiarization:
Familiarize yourself with the following; TOUCH SCREEN, EMERGENCY POWER SWITCH, MAINS POWER SWITCH.

$noztek-TOUCH-Versatile-Single-Screw-Desktop-Extruder-Fig- $1$$

STEP 2. Start-up procedure:
To turn on the machine, use the illuminated MAINS POWER SWITCH located at the back. Push the red illuminated EMERGENCY POWER SWITCH at the front of the machine to activate the machine. In an emergency, pushing the button will shut down the Noztek TOUCH/TOUCH HT completely.

STEP 3. Main Screen Overview:
The main screen provides comprehensive information about the actual current temperature in Celsius for individual heating bands and the motor speed in RPM (top row). TEMP 1 corresponds to the main heater band, while TEMP 2 corresponds to the pre-heater band. The second row displays the set temperature and motor speed. The third row features activation/status switches, and access to the Menu screen is available at the bottom.

To activate the heating bands, simply touch any of the temperature activation/status switches. Once activated, the Noztek TOUCH/TOUCH HT display will transition to the ‘warm-up’ screen (see image below). The Noztek TOUCH/TOUCH HT remains on this screen until the heating bands reach the set temperature or until the user manually aborts the heating process. The motor switch activates only after the warm-up phase, ensuring the motor runs safely thereafter.

STEP 3.1. WARM-UP SCREEN

This screen appears during the initial heating process or when the temperature falls below the target. The warm-up is essential to ensure that the barrel reaches a specific temperature before enabling the motor to run safely

STEP 3.2. Menu Screen
The Menu screen provides users with access to all of The Noztek TOUCH/TOUCH HT settings and additional functionalities, including temperature settings, speed settings, fan settings, and timer settings.

SET TEMP: Adjusts the desired temperature of the individual heating bands.
SET SPEED: Configures the desired revolutions per minute (rpm) for the D.C. motor drive.
FAN: ON/OFF: Activates or deactivates the fan.
TIME LEFT: Set a timer for automatically shutting down the DC motor drive and heating bands.

STEP 3.3. Temperature setting

This screen allows the user to set the temperature for each heating band. Users can achieve this either by using the sliders or the “+” and “-” buttons and then confirming with the “SET” button. To cancel any modifications, press “BACK”. The Noztek TOUCH allows a maximum temperature setting of 300°C for each heater band, while the Noztek TOUCH HT can reach up to 600°C.”

STEP 3.4. Motor speed setting
This screen allows the user to set the speed for the motor in RPM. Users can achieve this either by using the sliders or the “+” and “-” buttons and then confirming with the “SET” button. To cancel any modifications, press “BACK.”

STEP 3.5. Timer Setting
This screen allows the user to set a timer for shutting down the current session. This action does not power off the Touch but stops both the heating and the motor. Users can set the timer using the “+” and “-” buttons and then confirm with the “SET” button. To cancel any modifications, press “BACK.

STEP 4. Initiating Extrusion:
Add your pellets and, after the warm-up procedure, initiate the extrusion process by turning on the motor using the motor on/off switch. After a short duration, the plastic will emerge from the nozzle. Pull the filament through the guide. The extruded filament will be hot, so use heat-resistant gloves. Some materials may require immediate cooling after extrusion; turn on the fan using the fan on/off button to facilitate this. The operational set-up is now complete.

STEP 5. Shutdown Procedure:
When finished, turn off the EMERGENCY POWER SWITCH and MAINS POWER SWITCH. These instructions ensure the safe and efficient operation of the Noztek TOUCH TOUCH HT.
Additional Information:

Quality Measures:
Extrude approximately 5m of filament, switch off the motor, cut off the excess material, and then restart the motor. This helps eliminate air bubbles and metal particles in the system.
Colour Mixing:
Adding colours is a straightforward process. Mix the natural and colourant at the given ratio, then pour it into the hopper. It will take 10-20 minutes to observe colour changes.
Temperature Adjustments:
Adjusting the temperature also affects filament tolerance. Higher temperatures result in thinner filaments, while lower temperatures result in thicker filaments. Make adjustments in 5-degree Celsius increments.

Maintenance

Changing the Nozzle:
Before attempting this operation, ensure you use heat-insulated gloves. To switch between nozzle sizes, heat the unit to the temperature required to melt the material previously used. Wait for 10 minutes to ensure all material is molten. Unscrew the nozzle using a spanner, clean any excess plastic from the internal threads, and then screw on the new nozzle.
Maintenance:
Regular cleaning of your plastic extrusion tooling is crucial for prolonging machine life, reducing waste, and maintaining tighter tolerances for your final product. We recommend running purging agents like polypropylene through the barrel for cleaning. If this is not possible, use a wire brush and fine metal pick to clean the threads and screw assembly. If you are unsure how to clean the barrel, please contact the Noztek helpdesk for assistance.
Barrel Jam:
Depending on the resin type, you may occasionally encounter a barrel jam. If the motor starts labouring and slowing down during extrusion, immediately switch off the motor. To free the jam, increase the temperature to approximately 25-50 degrees Celsius above the recommended melting temperature of the material and leave it for 15–20 minutes. Then switch on the motor again; this should allow the screw to rotate, purging the barrel.
