With the material between the pliers and the nozzle, apply gentle pressure with the pliers and turn
the pliers to remove the oxidized filament material. Do not apply heavy pressure!
Remember, the nozzle heats up to 260° C (500° F) – that’s over two and a half times the boiling
point of water. Do not touch the nozzle or nozzle mount with bare skin during this process!
If this does not clear up any issues, you should try removing and soaking the nozzle in acetone
overnight to remove excess ABS material from the nozzle. Ultrasonic cleaning baths also work.
Removing / Changing the Nozzle
If the nozzle becomes blocked, you may need to remove it in order to unblock or change it
altogether.
To remove the nozzle, use the Withdraw button on the Maintenance dialog box to
remove as much filament from the nozzle as possible. Once the Withdraw has
completed and before the heater has a chance to cool below 200° C, use the
nozzle wrench provided in the toolkit that comes with your Afinia
H480 3D Printer.
Use the same process to replace the nozzle, being sure
to heat the extruder to at least 200° C before tightening
the nozzle back down.
Do not apply too much torque to the nozzle to avoid
twisting the heater assembly!
TIP: Heating the nozzle to 200° C will make it easier to remove and replace.
WARNING: Be careful when handling the heated nozzle and nozzle wrench once the
nozzle has been removed!
Cleaning the Platform
Regardless of the method of preparing the platform that you have chosen, a smooth surface will
improve your results.
• If you are using the FR-4 Board as the print surface, you should remove any remaining
filament material from the surface of the board before printing again.
• If you are using blue painter’s tape on the platform, you will need to replace the tape once
it becomes uneven. You may need to remove excess adhesive from the platform during
the process of replacing the tape.
Lubrication of bearings
The 3 axial bearings on the Afinia H480 3D Printer may occasionally require a bit of lubrication to
keep it operating smoothly. The recommended grease to use is lithium grease.
When lubricating the bearings, first clean off as much old grease as possible from the bearings
before applying new grease to the bearing. Slide the platform several times in the appropriate
direction to spread the grease evenly.
If you have any questions about lubricating the bearings, please contact Technical Support (see
page 42 for contact information).
Spare parts
Most of the plastic parts on the printer can be printed by the Afinia H480 3D Printer itself. If you
need spare parts for your printer, the files for the printable parts can be found in the C:\Program
Files\Afinia\Example\Spare Part folder on PCs and in the Afinia directory off the root of the
current User directory on Macs.
