Auxiliary feeder usage tutorial and troubleshooting
SV08 max uses an auxiliary feeder, which drives the gears through an independent motor and actively pushes the filament to the extruder, making it easier to install and unload the filament. It can also detect filament breakage, blockage, and entanglement, avoiding wasting more filament during printing.
Before using the auxiliary feeder, please confirm that the printer's firmware is updated to the latest version.
Installation of the filament: Cut the filament at a 45° inclined angle for easy installation of the filament.
Press the handle of the auxiliary feeder, load the filament, and check the indicator light of the auxiliary feeder to make sure the broken material detection has sensed the filament

Confirm that the filament has successfully entered the Teflon tube, click the switch of the auxiliary feeder, and the filament is delivered to the extruder head to complete the installation of the filament.
Unload the filament: Click the long unloading button, the nozzle will automatically unload the filament after heating is completed, and wait for the filament to exit before pulling out the filament.
1. No light:
No filament loaded.
2. Green light:
Filament loaded, filament transported normally for printing.
3. Blue light - filament entangled:
(1) The photoelectric switch is not activated, the spring does not rebound upward, and the discharge tube is stuck.
(2) The feed handle spring is loose, causing the filament to fail to feed properly.
(3) The Teflon tube has detached from the pneumatic connector, which preventing the filament from being properly fed into the extrusion head.
(4) The filament is entangled and cannot be printed normally.
(5) The filament is used up and needs to be replaced with a new filament (it takes 5-8 minutes to trigger this situation).
4.Red light - nozzle blockage, etc.:
(1) Nozzle blocked/thermal creep occurs/filament diameter issues prevent proper melting and extrusion.
(2) The extruder handle is loose, causing uneven gear marks on the filament.
(3) The discharge tube is stuck and the photoelectric switch cannot be triggered downward.
An error occurs, as shown below:
Please check the wiring of the auxiliary feeder, if the cable is detached or damaged, it will be prompted to report an error, you need to confirm that the cable is successfully connected to restart the printer.
Blue light
(1) Check the discharge pipe and spring, move the discharge pipe up and down, and confirm that the spring and discharge pipe are not stuck.
(2) Squeeze the handle of the auxiliary feeder to confirm that the handle spring of the auxiliary feeder is not detached and the filament is feeding properly.
(3) Please check the Teflon tube and pneumatic connector. If they are loose, please connect them in time.

(4) Check the filament and make sure it is not tangled or knotted. After the printer completes the long unwinding process, store the filament in time to avoid entanglement. If the same roll of filament is entangled multiple times, try to replace it with another filament and print again.
(5) After using the filament, please replace it. Please refer to the video tutorial on replacing the filament:
Red light
(1)Heat the nozzle to 240℃, remove the Teflon tube and open the extruder handle. If the filament cannot pass through after inserting it,.this indicates a clog in either the nozzle or heat break. Please refer to the cleaning tutorial video:
Thermal creep occurs. If the extracted filament shows an expanded tip or uneven extrusion marks, please check the current slicing temperature and select an appropriate printing temperature to avoid excessive heat causing heat break clogging.
Please try to change different types of filaments for testing and confirm that the wire diameter of the filament remains ±1.75mm. It is recommended to use high-speed filament for printing.
(2) Check the handle of the tool head, adjust the thumb screw to achieve proper spring tension and to confirm the filament can be extruded normally.
(3) Check the discharge pipe and spring, move the discharge pipe up and down, to verify that there are no obstructions in spring or tube mechanism ,and the discharge pipe can move downward normally.
