1. Remove the two material rack screws from the back panel. Align the material rack with the holes on the back of the machine and secure it with the two screws.
2. Connect the PTFE tube to the pneumatic fittings on the material rack and the machine.

2.3 Connecting CFS

(Users who have not purchased CFS can skip this step.)

2.3.1 Install the filament buffer

1. Install the filament buffer on the back of the printer and tighten it with two buffer screws. Ensure correct orientation.

2.3.2 Connect the PTFE tube and 485 cable

• The longer PTFE tube connects the CFS five-way connector to the buffer.
• The shorter PTFE tube connects the CFS buffer to the printer.
• The shorter 485 communication wire connects the CFS to the buffer.
• The longer 485 communication wire connects the CFS to the printer.

Connection Steps:

1. Connect CFS hub outlet and buffer: Insert one end of the longer PTFE tube into the CFS hub outlet (position a) and the other end into the buffer (position b).
2. Connect the buffer to the printer following steps A, B, and C.
3. Connect CFS and buffer Creality 485 cable: Insert the elbow into the buffer position c and the straight head into the CFS position d.
4. Connect the CFS to the printer using the 485 communication wire (6-pin straight connectors). Insert one end into position E on the CFS and the other end into position F on the machine interface.

Please clean up waste residue at least once every 24 hours to prevent blockage of the waste outlet.

2.4 Connecting Multiple CFS

(Users who have not purchased CFS can skip this step.)

Connect multiple CFS units in series using the provided PTFE tubes (yellow) and 485 cables (green).

Note: The current interface is for reference only. Please refer to the latest software/firmware UI on the official website for updates.

3. Product Usage

3.1 User Interface

The user interface consists of a navigation bar on the left and status information on the right.

• Navigation Bar:
  • Home: View machine temperatures (idle) or printing progress (printing).
  • Adjustment: Operate the machine, move axes, load filaments, etc.
  • File: Select print files and manage printing operations.
  • Function Setting: Configure network, camera, and other settings; view machine information.
  • Help: Export logs or view the machine wiki.
• Status Display: Shows Nozzle temperature, Hotbed temperature, and Chamber temperature. Parameters can be manually set.

Note: The current interface is for reference only. Due to continuous upgrades, refer to the latest software/firmware UI on the official website.

3.2 Loading Filament From Spool Holder

1. Hang the filament on the spool holder.
2. Thread the filament into the Teflon tube and push gently until it cannot be pushed further.
3. Manually set filament information on the screen: Navigate to Adjustment page → Filament → Edit. Set the filament brand, type, name, and color, then click 'OK' to save.

Extrude Process:

• Push the filament gently by hand and click 'Extrude' on the filament interface. The machine will automatically set the filament temperature and extrude the filament after heating.
• Observe the filament flow from the nozzle. If there is no flow, gently push the filament towards the extruder through the Teflon tube and click 'Extrude' again.

Retract Process:

• Click 'Retract' on the filament management page. The extruder will move to cut off the filament.
• Wait for retraction to complete, then extract the filament from the Teflon tube.

Note: The current interface is for reference only. Refer to the latest software/firmware UI on the official website.

3.3 Loading Filament From CFS

(Users who have not purchased CFS can skip this step.)

To avoid filament spool getting stuck, do not use cardboard spools with untreated edges or deformed spools.

Introduction to the filament management interface: The interface shows the spool holder (left) and CFS (right). Codes like '1A' indicate the slot number.

• RFID Button (a): Reads filament information. Displays remaining filament and color if successful; otherwise, shows '?' and enables editing.
• Empty Slot State (b): Displayed as '/', editing not supported.
• Filament Status: 'PLA' indicates ordinary filament that supports editing.
• RFID Reading: If RFID filament is read, the eye icon allows viewing information. For non-RFID, use the pre-loading button, wait for reading, then edit.
• Manual Editing: If '?' is displayed, click the edit button to manually input filament information.
• CFS Humidity Status (f): Green (appropriate), Orange (slightly high), Red (very high). Desiccant may need replacement.

Load/Unload Filament:

• Loading: Place filament in CFS, align with the Teflon tube, push gently, and release.
• Unloading: Ensure filament is not in the extruder. If it is, click 'Retract' first. Then, take out the filament.

4. First Use

4.1 Filament Setup

1. Put filament in and wait for tightening. RFID filaments do not require manual editing. For non-RFID filaments, '?' will be displayed, requiring manual editing.
2. Check if the filament information displayed on the screen corresponds to the filament in CFS.

Note: The current interface is for reference only. Refer to the latest software/firmware UI on the official website.

4.2 Print

1. Click the file on the screen, confirm the filament mapping status, and click 'Print'.
2. The printer will start printing.

Filament Selection:

• Area 'a' shows the color and type of material required by the print file (e.g., green background PLA indicates green PLA is needed).
• Area 'b' shows the mapping status. If a filament type is missing, the system may auto-select another color.
• If mapping fails, '--' is displayed, and manual selection is required.
• Enabling CFS allows printing with CFS filaments; otherwise, spool holder filaments are used. Multi-color files will be treated as single-color files.
• Check 'Print Calibration' to enable the auto-leveling function.

Note: The current interface is for reference only. Refer to the latest software/firmware UI on the official website.
